Development of HS 110ª Continuously-Milled Coiled Tubing GRADE DESCRIPTION: This is a new ultra high strength coiled tubing grade which exhibits yields strengths approximating 108,000 Ð 115,000 psi while maintaining good ductility. The grade exhibits superior low cycle fatigue life with moderate to high internal pressure levels without a tremendous sacrifice in life expectancy at low pressure levels. Even with the very high strength levels, this grade exhibits superior resistance to environmental cracking. (Caution: Even though this ultra high strength grade exhibits increased resistance to environmental cracking such as sulfide stress corrosion cracking, the resistance is inferior to the HS-90 coiled tubing grade and the lower strength grades. Care must be taken when selecting high strength coiled tubing for severe hydrogen sulfide containing environments.) APPLICATIONS:

The need arises for ultra high strength coiled tubing because of the following

(1) HIGH PRESSURE SERVICE Ð The higher mechanical properties permit higher pressure ratings at equal wall thicknesses. For example with 2Ó x 0.134Ó coiled tubing, increasing the yield strength from 70,000 psi to 90,000 psi to 110,000 psi increases the burst pressure based on Von Mises yield criteria from 9270 psi to 12,390 psi to 15,420 psi respectively. (2) LONGER REACH - The higher mechanical properties permit greater tubing loads which correlate directly to greater depths at equal tubing dimensions. (3) WEIGHT SAVINGS - The higher mechanical properties permit decreasing wall thickness for equal load and pressure capabilities. For example, a 2Ó x 0.134Ó coiled tubing with a 110,000 yield strength can sustain a greater internal pressure than a 2Ó x 0.175Ó with an 80,000 psi yield strength. TARGET PROPERTIES: The target properties are 110,00 ksi yield strength, 118,000 ksi tensile strength with an elongation of at least 22%. These values are target values because additional new heats of steel are necessary to define the statistical ranges and firmly establish production ranges.

QUALITY ASSURANCE SYSTEM OVERVIEW

A word about Precision Tube Technology's Quality Policy... Precision Tube Technology, Inc. is dedicated to the pursuit of excellence in the products and services that we provide to our customers. We recognize that the needs of our customers are the sole reason for our company to exist and that in order to achieve and consistently maintain the highest level of quality, every member of the company must be an active participant in the company's Quality Assurance programs and policies. The Precision Tube Technology Quality Assurance Manual is the company's formal guide for the methods and requirements necessary to achieve our standard of increasing excellence and to ensure compliance with all customer, internal, ISO-9001 and statutory requirements, but in recognition that perfection is a goal and not an achievement, all employees, vendors, and customers are encouraged to make any suggestions for improvements to products and services. A final statement to employees and vendors: this commitment to quality is absolute. Whenever a question arises that concerns quality, the decision will be in favor of improved quality. Following is an overview of the standard quality control steps that are taken in the manufacturing process for continuously milled coiled tubing: CHEMICAL ANALYSIS - Representative strip material from each mill heat is submitted for a chemical composition analysis. An independent laboratory verifies that the chemical composition meets PTT specification. RECEIVING INSPECTION - Each strip received is dimensionally checked for width and gauge, and visually inspected for slitting defects. Additionally, each strip is assigned a unique identification number which ensures traceability. RADIOGRAPHY - All strip bias welds are 100% radiographed (X-rayed) using a procedure exceeding the requirements of ASME Section V, Article 2. Unlike ASME Section VII or III, PTT's acceptance criteria allows no welding defects or repair of defective areas. CRUSH AND FLARE - The seam-weld integrity is verified by these two destructive tests using samples taken at the beginning and the end of each milled string. The Crush test flattens the tubing fully upon itself with the seam-weld oriented at the apex of the fold; no open defects are permitted in the weld. The Flare test stretches the open end of the tubing over a mandrel with a 60° taper; the tubing must expand 21% over the initial diameter before failure (splitting) and the seam weld cannot fail. The Crush and Flare tests are in accordance with ASTM A450.

QUALITY ASSURANCE SYSTEM OVERVIEW ( CONTINUED )

ELECTROMAGNETIC TESTING (Eddy Current) - As tubing is milled, the seam weld is continuously monitored using electromagnetic (eddy current) testing. The eddy current testing is calibrated at the beginning and the end of each milled string using standards with 1/32 inch holes drilled through the seam weld. The eddy current test station is equipped with an audible alarm and with an automatic marking system. This will identify precisely areas that may require further inspection.(i.e. magnetic particle testing and radiography) DIMENSIONAL INSPECTION - The beginning and end of each strip as well as the bias weld width and thickness is inspected at the assembly line. Samples from the beginning and the end of each milled string are dimensionally inspected for ovality (± 0.010 inches), wall thickness (minimum specified for nominal specified) and seam-weld mismatch ( ±10% of actual wall thickness). TENSILE TESTING - Full-section tubing samples from the beginning and the end of each string are tensile tested to verify the Yield Strength (0.2% Offset Method), Ultimate Tensile Strength, and Percent Elongation (2-inch Gauge Length). Tensile testing and determination of properties is in accordance with ASTM A370. MICROHARDNESS TESTING - Portable hardness tests are performed on all strip bias welds. Cross-sections of tubing samples from the beginning and end of each string are metallographically prepared for microhardness testing (Knoop Method). Multiple measurements are made in the seam-weld, associated Heat-Affected-Zone (HAZ) and unaffected base metal. Hardness in any area cannot exceed 22 HRC. METALLOGRAPHY - The prepared cross-sections are then metallographically examined to determine the degree of mismatch at the seam-weld and to examine the weld and HAZ for proper microstructure and normalizing. Photomicrographs are then taken of the seam-weld and become part of the QC Test Record. HYDROSTATIC TESTING - Each string is hydrostatically tested to 90% of the theoretical yield burst pressure for a minimum of 30 minutes. Test pressure and duration are recorded on a chart and become part of the permanent record. As the tubing is filled with water, a steel gauge ball of a specified diameter is run through the tubing to insure there are no obstructions. After hydro-testing, the test fluid is purged from the string using nitrogen gas.

C ALCULATION OF BURST YIELD AND COLLAPSE YIELD FOR ROUND TUBING

π OD2 – ID2 4

σ h = pi

OD2 + ID2 OD2 – ID2

σ r = – pi

where pi is the internal pressure, F is the tension force (weight here), ID is the tubing inner diameter, and OD the outer diameter. Substituting (1) - (3) into the following Von Mises criterion 2

we get pi =

where B = (OD2 + ID2)/(OD2 – ID2), S y is the yield strength. We should ignore the negative sign in (5) because it is physically insignificant. So, from the positive root, we can get the burst yield equation. pburst = i

Figure 1 shows the burst yield for a tubing with OD = 2.375", WT = 0.175" (using its minimum value of 0.167"), and 70,000 psi yield strength. Collapse Yield We assume no internal pressure. Denote the external pressure as p o . The axial stress is the same as that given by (1). The radial pressure at the inner surface is zero. σr = 0

NOTE: Because of friction forces, which cannot be determined readily, the actual length of free pipe may be longer than calculated. The formula assumes complete absence of friction. From Hook's law, if tubing is under a tension force F, then the elastic elongation is given by

∆L = F L E An (1) where ∆L = tubing stretch (in); F= axial force on tubing (lbs); L = free length of tubing (ft); A n = nominal cross sectional area of tube (in2); E = Young's modulus of elasticity (30,000,000 psi for steel). To determine the free point, pull the pipe into tension with at least 500 pounds of load over the hanging weight of the tubing in the hole. Make a visible reference mark on the pipe. Increase the pull on the pipe in increments of 1000 pounds over original tubing weight. Measure the amount of pipe stretch (∆ L). Subtract the original weight reading from the final pull weight (FD). Read the correct Free Point Constant (CFPC) from the table above for the coiled tubing involved and use the following equation: L = ∆ L CFPC FD (2) Where L = minimum length of free pipe (ft); ∆ L = Stretch (in); CFPC = Free Point Constant; FD = pull force difference (1000 lbs) Example: Determine the minimum length of free coiled tubing being stretched when a 10,000 foot string of 1.25” OD, 0.087” wall tubing stretches 39 inches with an applied pull of 5000 pounds over tubing weight. L = ∆ L CFPC = 39×760 FD 5

NOTE: Calculations assume the inside and outside fluid weight equal to 9 ppg and friction coefficient equal to 0.25. In a vertical wellbore, initially, the compressive force exerted on the bottom of the tubing is equal to the weight slack-off at the surface. However, as this compressive force increases, the tubing will buckle, first sinusoidally then helically. A friction force between the helix and the wall will be produced. This friction force increases as the slack-off at the surface increases. Thus, the compressive force at the bottom will reach a maximum since additional slack-off will be supported entirely by helix-wall friction above that point. The maximum compression load Fmax is given by: Fmax =

We EI

3rf

where We = effective weight = W – 0.052 (Aoρo – Aiρi) (lb/ft), Ao, Ai = outside and inside tube areas (in2), ρo, ρi = outside and inside fluid densities (lb/gal), I = bending moment of inertia (in4), E = modulus of elasticity (30,000,000 psi) r = radial clearance between tubing and hole (in), f = friction coefficient between tubing and hole, W = unit weight of the tube (lb/ft). From force equilibrium, an equation that governs surface slackoff and compression on bottom can be derived: Y =

e 2 X– 1 e 2 X+ 1

(2)

for a given maximum compression. Where X = ratio of surface slack-off over maximum compression, and Y = ratio of compression on bottom over maximum compression. Equations 1 and 2 can be used to calculate the compression on the bottom.

PRECISION TUBE TECHNOLOGY

SUGGESTED FIELD WELDING PROCEDURE (GTAW) FOR C OILED TUBING GRADES HS70,HS80,HS90, HS110

This guideline may be used to qualify weld procedures for all gauges and grades of PTT coiled tubing up to and including HS-110™. The success or failure of butt welds on coiled tubing is highly dependent on the skill of the welding personnel, the type of welding equipment used, the method of heat extraction during welding, and the level of non destructive examination after the weld is complete. Caution should be exercised when using strings containing butt welds because the quality of the weld effects the yield strength and the resistance to environmental cracking. As with all welding procedures, Precision Tube Technology recommends qualifying a weld procedure by mechanical testing samples prior to welding on actual strings. Two things need to be considered prior to welding coiled tubing: the welding equipment and the welding personnel. These two variables dictate joint design, alignment clamp design, and chill block design. Joint Design: Typically a square butt weld will be used for tubing which is less than or equal to 0.125" thick and a "V" groove will be used for heavier wall tubing. However, the decision to use a square butt joint versus a "V" groove should be based on the available welding equipment and skill of the operator. For instance, an automatic orbital welding machine may be capable of a full-penetration weld in a single-pass on 1.25" OD X 0.156" wall coil tubing. However, in the field where less sophisticated equipment is available, such tubing may be considered "heavy-gauge" and a multiple pass, "V" groove procedure would be used. When utilizing a "V" groove procedure, the bevel angle may vary from 30° to 45° depending on the amount of penetration the equipment and/or operator is capable of. A good rule of thumb for V-groove welds is a 37° bevel with a 1/16" gap and a 1/32"-1/16" land. For manual square groove butt welds, PTT recommends using a 1/32" to 1/16" gap between tube ends. Alignment clamps: Using an orbital welding machine will also dictate the shape of the alignment clamp: low clearance alignment clamps may be used with automatic equipment whereas a manual weld will require more access to the entire girth of the weld. The alignment clamps should ensure proper alignment of the axis and gap maintenance during welding. Chill blocks: Standard chill blocks for manual welding should be made from copper material, 3"-4" long, 3/8" (minimum) thick and the ID of the chill block should match the OD of the pipe. The thicker the chill block is, the more heat it will extract; chill blocks measuring 0.5" - 1.0" thick are often used in the field. The end of the chill block may be beveled at a 30° to 45° angle for easier access. Chill blocks for orbital welding equipment will have to be custom designed and tested to ensure proper heat extraction. PTT recommends that all HS-90™ and HS-110™ strings be welded while using water cooled chill blocks for heat extraction. In addition, water cooled chill blocks should be used on lower grades of coiled tubing with wall thicknesses greater than and including 0.190". Standard chill blocks may be used on lower grades with wall thicknesses less than 0.190" however, caution should be used as lower yield strengths may exist. Water or ethylene glycol circulation may be applied with running tap water or a 5 gallon bucket with a small pump. Soldering or brazing a copper tube to the back end of the chill block will provide an adequate couple between the chill block and the water source as shown below.

SUGGESTED FIELD WELDING PROCEDURE (GTAW) FOR C OILED TUBING GRADES HS70 THRU HS110 (CONTINUED)

Below is a step by step procedure for welding coiled tubing. 1. Straighten both ends of tubing to be welded. Cut ends of tubing square or machine a bevel using a beveling tool, grinder, or file. Deburr all cut edges. 2. If the tubing is wet inside, place a small amount of soluble tissue paper (such as Kleenex or toilet paper) about 12" from the end of the tube to stop seepage. 3. Using a small flat/curved tip chisel, or a small round/curved file, taper/remove the inside weld bead 0.25"-0.5" from the end of the tube. A chisel ground with a curve similar to the ID of the pipe works best for this procedure. Extreme care should be taken not to nick or cut the ID of the pipe. If a nick or cut is made into the tube wall, or any of the pipe wall is filed off, cut that section off and start over. It may be necessary to remove the bead before doing the final weld preparation in step 1. 4. Polish the end of the tube using emery cloth or a fine wire brush about 2 inches back from the end on the O.D. and about 1 inch back from the end on the I.D. The final appearance should be smooth shiny metal on the O.D. and I.D. of the tube. Circumferential grooves and grinding marks significantly decrease fatigue life and should be polished smooth using emery cloth or a fine wire brush. Please assure that all sand paper and emery cloth is NOT aluminum oxide. 5. Use alcohol or other appropriate degreasing agent to clean the inside and outside of the tube. Assure that the surfaces near the weld prep are clean and dry. Do not use gasoline. Avoid contaminating the clean surfaces during alignment in step 6. Re-clean if necessary after alignment. 6. Position tube ends in a fixture so that the ends are butted together. Use a straight edge (at least 8 inches long) to assure alignment on all axes. In order to maintain the proper gap width, use a small piece of weld consumable between the two pipes during the alignment process. It is also recommended that you leave the spacer wire in while welding the first side of the tube to prevent the gap from closing. Remove the spacer before welding the other side. NOTE: It is extremely important to assure that the tubes are butted squarely and the tube lengths adjacent to the weld are straight. 7. Position chill blocks (heat sinks) on either side of the joint to be welded. For groove welds, the chill blocks may be moved to the edge of the groove during the root pass, and then moved approximately 3/16" away from the edge during subsequent passes. Chill blocks for material thicker than 0.190" or grades greater than HS-80‘ should be water cooled. Using heat sinks without water coolant may cause high hardnesses in the heat affected zone and cause premature failure. For square butt welds, the chill blocks should be placed about 3/16" from the edge of the tube. See the "Chill Block" section on page 1 for more information on chill block design. 8. Wind curtains shall be positioned to insure there is no air movement in the vicinity of the weld during the welding process which could interrupt the cover gas. 9 . The full penetration weld shall be accomplished using the GTAW (a.k.a. TIG) process with high frequency start and a 3/32-inch thoriated tungsten electrode. Scratch starting may contaminate the weld and is not recommended. A 75%Helium/25%Argon shielding gas mixture works well for this type of full penetration weld. Welding parameters should be DCEN, 50-100 AMPS, 9-15 VOLTS, and 1-2.5 ipm, however these may vary slightly based on the welding machine you are using. 100% Argon shielding gas is suitable but will require higher amperages for full penetration, and may increase HAZ (Heat Affected Zone) hardnesses. Precision Tube Technology recommends using AWS ER70S-2 1/16-inch diameter weld consumable for all welds on HS-90‘ grade tubing and below. (continued)

PRECISION TUBE TECHNOLOGY

SUGGESTED FIELD WELDING PROCEDURE (GTAW) FOR C OILED TUBING GRADES HS70,HS80,HS90, HS110

For HS-110‘ coiled tubing, Precision Tube Technology recommends using AWS ER80SD-2 1/16" filler material. The weld shall be made using a single-pass stringer bead with a 0.25 - 0.50 inch overlap on the start and stop. A small amount of oscillation may be necessary to assure tie in of both sides of the weld. However, large amounts of oscillation should be avoided as wide beads tend to decrease fatigue resistance of the string. 10. Remove chill blocks and allow to cool to touch after each pass. When using water cooled chill blocks, leave blocks in place, and allow blocks to cool to touch before proceeding. 11. After the weld is complete, remove chill blocks and dress the weld bead to within -0.000/+0.005 in of the tube surface. The finish shall be smooth with no nicks or cuts. Note: do not remove material from the parent tube surface. Factory welds are dressed with a small hand grinder to remove the cap of the weld, and then filed smooth with a flat file. Final finishing is done with emery cloth until smooth. It is necessary to remove the cap prior to radiography to ensure a full penetration weld. 12. It is vital that X-rays be made of each weld. A procedure following ASME Section V, Article 2 using the double-wall, double-viewing technique for complete coverage and capable of very high quality (2T-hole #7 penetrameter) is recommended for detecting small defects. Experience has shown that lack of penetration and even very small defects can lead to sudden failure. Welds are rejectable for any defect: porosity, undercut, lack of penetration, lack of fusion, cracks or underfill.

SUGGESTED PROCEDURES FOR ATTACHING 1502 TYPE FITTINGS TO CT WORKREELS

TUBE TECHNOLOGY

When making up the 1502 fitting to the coiled tubing work-reel, it is possible that the weld point at the juncture of the tube and the 1502 fitting can be put into a stressed condition if certain procedures are not followed. If the proper equipment is not used, stress can be caused when the tube is bent to accomodate the usually short distance and tight angle between the core of the workreel and workreel connection for the 1502 fitting. Without the aid of a hydraulic bender or other suitable mechanical means, it can be very difficult to bend the tube without stressing the weld connection. It is very important that the tube exits the 1502 fitting in a straight line for a distance of approximately 6" to 8". See Fig. 1 below. Fig. 1

Correct

Incorrect

The suggested procedure to avoid stressing the weld at the junction of the tube and the 1502 fitting is as follows: 1. Take a short length of tube [ approx. 10'] of the same O.D. as the tube to be spooled onto the workreel. Using a hydraulic tube bender, form a template so that the tube will enter the workreel from the core, presenting the end of the tube to the workreel connection. Confirm that the last 6" - 8" of the tube is straight, this will avoid stressing the weld joining the tube to the 1502 fitting. See Fig. 2 below. Fig. 2 Template

2. Weld the 1502 fitting to the end of the tube to be spooled onto the workreel, then spool off a short length of tube and duplicate the shape of the template using the hydraulic bender. See Fig. 3 below. Fig. 3 TEMPLATE TUBING BENT RELATIVE TO TEMPLATE

1502 THROUGH-FITTING WELD PROCEDURE (F OR 1018 MILD STEEL ONLY )

TUBE TECHNOLOGY

1. The 1502 male- (wing-) half should be bored out 0.020 ± 0.010 over the tubing outer diameter. This may reduce the sealing face width on the fitting for 2-3/8"Ø coil tubing; however, experience shows this does not reduce its ability to seal-off. Also re-machine the flat on the tail end of the fitting (0.250 to 0.260 inches wide) for the fillet welding the tubing to the fitting. 2. Clean the outside surface of the tubing where it will be fillet welded to the end of the fitting (refer to figure). An area 1 inch to either side of the weld area should be cleaned to bright metal removing all rust, paint, grease and oil. 3. File the end of the tubing square and remove any burrs. 4. Degrease the inside of the fitting and outside of the tubing with alcohol or other suitable solvent; do not use gasoline. 5. Insert the tubing into the fitting until the tubing comes even with the end of the fitting sealing face. Pull the tubing back 1-1/2 times the tubing thickness. This will leave a right-angle surface to which a fillet weld will be made. 6. Using the manual Gas Tungsten Arc Welding (GTAW) with ER70S-2 filler metal (1/16 inch diameter) make a small fillet weld at the tail end of the fitting. The weld should be about 1/8" thick, or half the width of the flat. This weld should be made in multiple passes not one pass. After making the first (root) pass, the weld should be inspected using wet fluorescent magnetic particle testing to verify the absence of weld defects. The mag particle solution should be thoroughly cleaned from the weld area before completing the second and third weld (cover pass). Use a blacklight to verify all mag particles are removed. Complete the outside fillet weld by making two side-by-side GTA weld beads using the filler wire. Do not "clean-up" the weld appearance by remelting the outside weld beads using the GTAW torch without filler wire. Use a small grinder or file to do this. Mag particle test the weld. 7. Make the fillet weld on the end of the tubing at the "mouth" of the fitting using the GTAW process with ER70S-2. Filler wire must be added to this weld to prevent cracking of the weld and to put a rounded surface on the weld surface. 8. Mag particle test the weld.

Methods of Determining the Operational Life of Individual Strings of Coiled Tubing. LAWRENCE W. SMITH

ABSTRACT Traditionally the amount of work experienced by a coiled tubing string is recorded as “running feet”, i.e. the depth to which the string is run downhole, measured one way. The problem with this method is that it fails to account for the majority of the events (the bending cycles) that actually fatigue the tubing. The majority of the fatigue incurred by a coiled tubing string is the result of multiaxial cyclic plastic strain that occurs as the string moves from the work reel to the guide arch and then is bent around the guide arch as the string is directed downhole. Under normal conditions once the tubing enters the well bore the amount of plastic strain experienced is greatly decreased or completely eliminated. It is, therefore, the repeated coiling and uncoiling of the work string that fatigues the tubing. During the past two years a series of tests utilizing coiled tubing service rigs have been undertaken to determine and quantify the effect of various factors involved in the bending cycle. The preliminary results of these ongoing tests indicate that the most significant variable factors affecting the life of the tubing string are the bending radius and the internal pressure present in the tubing as it is being bent. More recent tests indicate that the wall thickness of the coiled tubing is also a more significant factor than originally anticipated. It has now been well documented that as the internal pressure increases, the number of bending cycles that the string can safely experience drops. The current series of tests should establish guidelines for expected cycle life at various pressures. Further tests with different diameters and wall thicknesses will expand the data base of relationships. As a result of these tests we are proposing the establishment of a new unit of measure: the Pressure Cycle Unit. This unit would be the equivalent of one back and forth bending cycle over a standard coiled tubing guide arch at 2,000 psi

internal pressure. New systems are now being developed that will use this new unit of measure as a way to track the degree and location of accumulated fatigue within a string of coiled tubing.

INTRODUCTION Due to the improved reliability of materials and techniques and the growing demand for economy, the downhole coiled tubing service industry is becoming involved with an increasing percentage of well workovers. In addition to the greater number of workovers being accomplished with coiled tubing, the operating parameters (depth, pressure, type of job) of workovers for which coiled tubing is considered are also expanding. As a result of these increased demands coiled tubing service companies as well as production companies are now asking for more accurate methods of predicting and measuring the safe working life of coiled tubing. The development of new coiled tubing procedures that utilize a bi-directional reversing action of the string (often referred to as “yoyoing”) over relatively short segments and under high pressure, have made the practice of recording running feet as an indication of accumulated work obsolete. Under certain conditions fatigue damage can become severe in a very short time span even though a particular work string is relatively new. The working life of a coiled tubing string is affected by various factors: mechanical damage, corrosion damage, damage incurred by exceeding the ultimate load capacity of the string, and damage due to cyclic plastic strain or fatigue. All but the last of these factors usually occur on a random basis that can be controlled or at least observed and quantified by the operator. But due to practical design limitations of coiled tubing equipment the degree of bending that the tubing experiences always exceeds the elastic limits of the material. Since the

tubing is subjected to plastic strain when it is reeled or un-reeled, damage is being accumulated constantly as the string is used and for this reason the coiled tubing work string must be considered to be a consumable material. Unfortunately this "rate of consumption", or accumulated damage, is not uniform throughout the string and makes the task of predicting acceptable limits quite difficult. This paper will examine the dynamics of fatigue as it relates to coiled tubing and propose new methods of recording the accumulation of fatigue.

elastic limits of 1-1/4" tubing are exceeded at diameters of less than 30 feet, it is evident that plastic strain is a constant factor but it must be noted the amount of strain incurred on the reel will vary throughout the length of the string due to progressive changes in bending diameters as the tubing is wound on the reel.

As previously indicated, the practical design limitations of coiled tubing equipment require bending diameters that exceed the elastic limits of coiled tubing. The points at which the elastic limit is exceeded in a normal equipment rig up are the work reel and the guide arch or “gooseneck” (see fig. 1). Plastic deformation can also occur in the injector and at the stripper but occurrence at these locations is usually the result of operator error or improperly adjusted or worn equipment.

As the tubing leaves the reel it next passes over the guide arch which is usually positioned 30-100 feet from the reel. The guide arch consists of an arc of rollers that support the tubing as it is guided through a turn of more than 90° to align with the wellbore. The radius of the guide arch arc may vary from 48 inches to 84 inches depending on manufacturer. This bending radius is generally more open than is the bending around the reel but it has been suggested that the open spacing of the rollers may concentrate bending moments more on the guide arch than on the reel where the tubing is supported continuously by underlying wraps of tube. Recent tests have indicated that size and position of the guide arch rollers have more impact on tubing fatigue life than does reel diameter.

The first point at which the tubing is exposed to plastic strain is on the work and storage reels. Coiling diameters on these reels can range from 48 inches to as much as 135 inches. Typically a modern work reel will have a drum core diameter of from 72 inches to 82 inches. Each wrap, or layer, of tubing will increase the bending diameter by a factor of two times the tubing O.D. Since the

As it leaves the guide arch the tubing enters the injector, a set of opposing drive chains consisting of a series of machined blocks. The machined surfae of the blocks conforms closely to the surface of the tubing and the tubing is gripped by a squeezing action as the chains are forced closer together. The amount of pressure (commonly referred to as skate pressure) used to grip the

tubing is another of the controllable variables that can have a significant impact on tubing life. If the pressure is increased to a level that can deform or oval the tube, tubing life is usually reduced due to a “ballooning” action that swells the diameter of the tube. As the tubing leaves the injector it is pushed through a pressurized “stripper” into the coiled tubing unit’s BOP. After it exits the stripper and enters communication with the wellbore, the series of bending and compressive forces to which the tubing was subjected in its path from the reel through the stripper are greatly reduced and in a normal operation the tubing is subjected to only elastic and not plastic strain while in the wellbore. In the past it has been generally assumed that the point of greatest stress was in the area immediately below the injector since, when the majority of the work string is in the wellbore, that is the point of greatest load due to string weight. But unless the tubing becomes stuck downhole and excessive pull is exerted, the entire string weight will not exceed the elastic limits of the tubing. It is, therefore, the area between the reel and the stripper in which virtually all of the plastic strain occurs. In fact, fatigue failure most often occurs at a point on the underside of the tubing between the guide arch and the reel as the tubing is coming out of the hole. DYNAMICS OF THE FATIGUE PROCESS Fatigue is the progressive, localized, permanent structural change that occurs in a material when it is subjected to repeated or fluctuating strains at nominal stresses that are often much less than the tensile strength of the material. The process of fatigue consists of three stages: 1. Fatigue damage leading to crack initiation. 2. Crack propagation or growth. 3. Final, sudden failure of the remaining cross section. It is the last, dramatic phase that is usually the first visible evidence that fatigue has occurred. The majority of the cycle life of a string of coiled tubing takes place prior to crack initiation. It is probable that due to the extreme plastic strain to which the tubing is subjected as it is coiled, once the crack starts it grows relatively quickly to the point of failure. In typical low- cycle fatigue (LCF), micro fatigue cracks often initiate at some point of discontinuity on the material surface or in the microstructure matrix. During cyclical stress loading, the longer stress concentration points can be

avoided, the longer the cycle life. In coiled tubing two areas of concern would be corrosion pits on the inner tube surface and the change in microstructure that occurs next to a butt weld. Fatigue cycle tests on coiled tubing units during the past three or four years have established that two of the major factors that impact cycle life of coiled tubing are the bending radius and the internal hydrostatic pressure. Since the bending radii often exceed the elastic limits of the material, their effect is easily understood. What has been more difficult to explain is the dramatic effect that internal pressures that are well below the plastic limits of the tube has on the decrease of cycle life. A typical example would be tests conducted on tubing that has an internal yield strength, i.e. limit of elastic, of 10,000 psi that may sustain over 200 bending cycles to failure with no internal pressure but fail in only 40 cycles when subjected to an internal pressure of 5,000 psi. Another often observed phenomena that has not been fully explained is the previously mentioned fact that fatigue failure most often occurs on the underside of the tubing between the guide arch and the reel as the tubing is coming out of the hole. Examination of these failures and research into the process of LCF has led this writer to the following hypothesis of the dynamics of this mode of coiled tubing fatigue failure. Crack initiation occurs on the lower internal tube surface that is subjected to tensile plastic strain as it passes back and forth over the guide arch. Note that due to the geometry involved, the upper internal tube surface is subjected to compressive stress rather than tensile. After the crack initiates it is subjected to a hydrowedge effect in the following manner. The crack is opened as the tubing is bent over the guide arch radius. As the crack opens it is filled with fluid present in the tubing under high pressure. Then as the section of tubing containing the crack is straightened as it leaves the guide arch toward the reel, the crack closes and the non-compressible fluid in the crack acts as a wedge causing further matrix separation. This type of hydrowedge effect on LCF cracks was noted by Ohji, Ogura, et. al.1. This wedge action probably occurs on both sides of the guide arch but the multiaxial loading of the tubing in the chains may provide enough support to limit the effects of the wedge cracking action. In the area between the arch and the reel however, there is very little load on the tubing and this lack of counteracting force may increase the magnitude of the hydrowedge effect.

Multiaxial low cycle fatigue is a complex problem that, due to the large number of variables present, is difficult to predict by mathematical modeling alone. Also, seemingly slight differences in equipment design and condition, even in coiled tubing units that are quite similar in most respects, may produce significantly different results related to fatigue damage. For these reasons it is important that when attempting to predict fatigue life, an accurate record be kept of the work to which a specific string of tubing has been exposed so that an empirical data base for the unit can be established. Work in this case is defined by the number of plastic strain cycles that a string has experienced. Since the majority of this damage occurs in the guide arch / reel zone, it is vital that the areas of the string that are subjected to repeated wear in this region are identified and the number of cycles through this zone recorded for each area in the string. To facilitate this process the following system is suggested.

4. The PCUs that each element of a string are exposed to should be recorded and accumulated throughout the life of the string. A sample layout of a string plot with accumulated PCUs for each element of the string is shown in Fig. 3. An example of the plot for the same string after additional use is shown in Fig. 4.

1. An accurate record should be maintained for each string of coiled tubing.

Due to basic equipment design, low cycle fatigue damage is a function of all coiled tubing work. It occurs every time the tubing is cycled and the effects are cumulative. The majority of this type of damage is the result of plastic strain that occurs as the tubing traverses the guide arch / reel region and for this reason an attempt should be made to note the sections of the tubing string that experience the most cycles through this area. Empirical testing has demonstrated that the internal pressure present in the tubing as it moves across the guide arch has a very significant impact on the cycle life of the tubing. The relationship of internal pressure to cycle life is inversely proportional: as internal pressure increases, cycles to failure decrease. Note that this relationship has only been shown to exist when the tubing is moving. It is probable that internal pressures present when the tubing is static, so long as they remain within the elastic limits of the tubing, have little effect on tubing life.

2. A plot of the entire string length should be established with regular divisions or section elements identified within the string. If records are maintained manually it may be practical to consider the string to be a series of 1,000 foot elements. Ideally an on board computer would be tied into the operating system of the coiled tubing unit so that depth and pressure could be automatically logged for each foot of the tubing as it moves back and forth across the guide arch. 3. The internal pressure present in the tube as it is being moved must be taken into account. Preliminary tests have so far suggested the following pressure relationships on one size of tubing: If (1) back and forth cycle from the reel across the guide arch at an internal pressure of 2,000 psi is considered to have a value of (1) pressure cycle unit (PCU), then (1) cycle at 3,000 psi would equal 1.5 PCUs, (1) cycle at 4,000 psi would equal 2.0 PCUs, and (1) cycle at 5,000 psi would equal 3.0 PCUs, the quantum jump between 4,000 psi and 5,000 psi being determined by empirical data gathered from tests. Note that these values are examples of relationships only and should not be used arbitrarily to determine life expectancy. A significant data base must be established for each size/gauge combination, i.e. 1-1/4" O.D.

5. The location of all butt welds within the string should be noted on the plot with special attention paid to the PCUs that accumulate in the butt weld area. Both fatigue theory and historical evidence point to the fact the heat affected zone of a butt weld is especially vulnerable to the effects of low cycle fatigue. The string plot should reflect areas of observed or suspected damage and periodic inspections of changes in diameter and roundness should also be recorded and compared. CONCLUSION

The large number of variables that impact multiaxial low cycle fatigue probably preclude the development of accurate mathematical models capable of quantifying and predicting this type of accumulated damage. For this reason it will be necessary to generate a data base from the results of coiled tubing cycle tests. Because of the requirement to test each size tubing several times, under varying pressures, it is expected that this information will continue to be accumulated by testing at coiled tubing service companies when equipment is avail-

able. It should be noted that an increasing number of companies are expressing an interest in this type of testing and, it is hoped, the coming year should see an accelerated accumulation of data. Service or production companies needing information on test procedures and/or the availability of test material are encouraged to contact the author. Limited amounts of test material will be available on a no charge basis. REFERENCE 1. Brown, M. W. and Miller, K.

Equation determines pressure drop in coiled tubing Yong S. Yang Precision Tube Technology, Inc. P. O. Box 24746 Houston, Texas 77229 Telephone: (281) 458-2883 Fax: (281) 458-2886 E-mail: [email protected] When using coiled tubing (CT) as a flow pipe, operators are usually concerned with the pressure losses for the fluid, among other things. A single equation that determines the pressure drop is therefore useful, especially in computer-aided design and operation. It is the purpose of this short article to present such a single equation that determines pressure drop of coiled tubing for incompressible fluid-flows.

Equations Based on mechanical energy balance, the differential pressure drop, – dp, over a differential distance dL of single-phase flow in a pipe can be derived as (i.e., Roberson and Crowe, 1985) 2 2 – dp = ρ du + ρ g dz + 4 f ρ u dL 2 di (1) where ρ is the fluid density, u is the flow velocity, z is the vertical coordinate, g is the gravity acceleration constant, di is the inner diameter of the pipe, and f is the friction factor. The first, second, and third terms in the right hand side of Eq. (1) are the pressure drops due to kinetic energy, potential energy, and friction force, respectively. Applying Eq. (1) to a section of CT string with length L (see Fig. 1), and assuming uniform flow velocity, we get

2 – ∆p = ρ g L sinθ + 4 f ρ u L di

where

(2) where θ is the angle between horizontal and the direction of flow. When the flow is upward, 0° < θ < 90°; when the flow is downward, – 90°< θ < 0°. For horizontal flow, θ = 0°; and vertical flow, θ = 90°. To determine the pressure drop due to the friction force, we should first calculate the friction factor, f. The friction factor is affected by the roughness but not dependent on the material of the pipe. The friction factor is not a constant. It decreases as the Reynolds number (R e ) increases, up to fully turbulent flow. Once the flow is fully turbulent (very high R e number), the friction factor remains constant. It then only depends on the relative roughness (ε / di ) but not the Reynolds number. The friction factor can be obtained from the Moody diagram (Moody, 1944), which was based on experimentation. However, for computer-aided design, a single equation for the friction factor would be useful. Such a single equation determining the friction factor for all Reynolds numbers (laminar, transitional, and turbulent flow) was developed by Churchill. This equation can be written as (see Churchill, 1977) f=

16 B = 37530 (5) Re where R e is Reynolds number and ε is the effective roughness, which is usually taken to be 0.0018 inch for CT string. The Reynolds number can be determined as (6) Re = 4 ρ Q π µ di 2

where Q (= u π di / 4) is the flow rate (in BPM) and µ viscosity (cp). The single Eq. (2) determines the pressure drop due to friction force and potential energy. The friction factor is determined by Eqs. (3) – (6). To express Eq. (2) as a relation between pressure drop (psi) per 1,000 ft and flow rate (BPM), the following conversion factors are used: 1 BPM = 42 gal/min (7) 1 gal = 231 in3 (8) 1 lb = 453.6 g (9) 1 in = 2.54 cm (10) The pressure drop (psi) per 1,000 ft is then: –

∆p = 6.9444 ρ sinθ + 3051.7 f ρ Q 1,000 ft d5i

2

(11) where ∆p is in psi, ρ in lb/ft 3, di in inch, and Q in BPM.

From Eq. (11), if θ ≥ 0° (horizontal or upward flow), there is always a pressure drop. Both friction force and potential energy contribute to the pressure drop. However, if θ < 0° (downward flow), the potential energy contributes to a negative pressure drop (positive pressure gain). Whether the net pressure of fluid drops or gains depends on the competition between potential energy change and dissipated energy due to friction force.

Calculation Examples We now use Eq. (11) to illustrate an example for the calculation of pressure drop in a CT string. As shown in Fig. 2, a CT string with OD = 2” and wall thickness 0.156” is used to inject water (density = 62.31 lb/ft3, viscosity = 0.9784 cp) into well 1 to force oil to flow into well 2. The water flow rate in the CT string is 3 BPM. What is the pressure drop per 1,000 ft in the vertical and horizontal sections of the CT, respectively? What is the total pressure drop from the surface to the bottom? If the pressure at the bottom is 3,000 psi, what is the pressure required to pump the water at the surface? The tubing inner diameter di = (2.0” – 2×0.156”) = 1.688”. (a) For the vertical section, because water flows downward, θ = – 90°. Substituting ρ = 62.31 lb/ft 3, Q = 3 BPM, µ = 0.9784 cp and d i = 1.688” into Eq. (6), we have R e = 240824. Then, we can calculate A and B from Eqs. (4) and (5). The friction factor is thus determined from Eq. (3), f = 0.00265383. Once the friction factor is determined, the pressure due to the friction force can be calculated, which is 331.2 (psi/1,000 ft). The pressure drop due to the potential energy [first term in Eq. (11)] is – 432.7 (psi/1,000 ft). Hence, the pressure drop in the vertical section is – 101.5 (psi/1000 ft), which in fact is the pressure gain because of the water weight. (b) For the horizontal section, θ = 0°. There is not potential energy change, so the first term in Eq. (11)

does not contribute to pressure drop. The pressure drop is only due to the friction force, which is 331.2 psi/1,000 ft. (c) The total pressure drop should be the sum of the pressure drops for both vertical and horizontal sections. This sum is 4×331.2 – 8×101.5 = 512.8 (psi), which is the total pressure drop from the surface to the bottom. (d) The required pressure at the surface to pump the water into the well is thus 512.8 + 3,000 = 3,512.8 (psi). Fig. 3 shows the pressure drop curves based on Eq. (11) for water flowing through a CT string for three cases (θ = – 45°, 0°, and 45°).

Conclusions Eq. (11) is a single equation that determines the pressure drop for all fluids in a CT string. The friction factor is determined by Eqs. (3) – (6). There is always a pressure drop for horizontal or upward flow. But for downward flow, the pressure drop due to friction force has to compete with the pressure gain due to potential energy change. The net result would determine pressure drop or gain. Eq. (11) is suitable for computer-aided pressure drop calculations.

Collapse Pressure of Coiled Tubing Yong S. Yang Precision Tube Technology, Inc. P. O. Box 24746 Houston, TX 77229 U. S. A. Telephone: (281) 458-2883 Fax: (281) 458-2886 E-mail: [email protected] Abstract T he collapse pressure is a measure of an external force required to collapse a tube in the absence of internal pressure. It is defined as the minimum pressure required to yield the tube in the absence of internal pressure. Coiled tubing is sometimes used in high-pressure wells. If the external pressure becomes too high, the coiled tubing will collapse. This could not only lead to serious well-control problems, but may result in extensive fishing operations. A reliable safety criterion of collapse pressure for the coiled tubing is needed by the coiled tubing operators. Theoretical models of collapse pressure are well developed for perfectly round coiled tubing but not for oval coiled tubing. Coiled tubing is initially manufactured with nearly perfect roundness, sometimes having a small ovality (typically ≤ 0.5%). Perfectly round CT becomes oval owing to the plastic mechanical deformation of the coiled tubing as it spooled on and off the reel and over the gooseneck. As the cycling continues, the ovality usually increases. This ovality significantly decreases the collapse failure pressure as compared to perfectly round tubing. In this paper, an analytical model of collapse pressure for oval tubing under axial tension or compression is developed based on elastic instability theory and the von Mises criterion. The theoretical model shows satisfactory agreement with experimental data.

I. Introduction Safety remains the primary issue when using coiled tubing in the field. The fatigue life limit of coiled tubing due to cyclic bending as well as the collapse pressure limit of coiled tubing under high external pressure are two important factors that must be considered before operating the coiled tubing. Standard specifications, especially those of fatigue life limit and collapse limit, for using coiled tubing is no doubt needed by users. With the increasing use of coiled tubing in the oil and gas industry, fatigue life as well as collapse theories will become more and more mature, and eventually standard specifications will be obtained. While the collapse problem is addressed in this paper, the fatigue problem will be studied in a separate paper.

at which the tube fails due to some kind of instability. Usually, the collapse pressure is classified into four categories from the modes of failure: yield strength collapse; plastic collapse pressure; elastic collapse pressure; and transition collapse pressure. For detailed descriptions of the above categories, consult Lamb (1995) and API Bulletin 5C3 (1994).

I n this paper, we use yield strength collapse for perfectly round tubing and a combination of yield strength collapse and elastic collapse for oval tubing. To be more exact, our collapse pressure should be referred to as collapse yield. But for the reason that the term "collapse pressure" is used widely, we do not distinguish "collapse pressure" and "collapse yield". We use them without distinction.

T he collapse pressure or collapse yield is defined as the required minimum pressure to yield the tube in the absence of internal pressure. Because the ideas and formulas developed for perfectly round tubing are useful for developing theory on oval tubing, we first review works on collapse of perfectly round tubing. A limit curve for collapse of the perfectly round tubing under axial tension or compression load is then constructed based on analytical results from stress analysis and the von Mises criterion. Next, an analytical model of collapse failure pressure for oval tubing is developed based on elastic instability theory and the von Mises criterion. Finally, the theoretical model results are compared with experimental data. The comparison shows satisfactory agreement.

II. Collapse Pressure of Perfectly Round Tubing 1. Analytical Results from Stress Analysis T he critical point, at which yielding would first occur, is always at the inner surface of the tubing (Yang, 1995a). At the inner surface of the tube, the radial stress, hoop stress, and axial stress can be derived as follows (see for example, Boresi et al., 1978).

σr = 0

T he collapse pressure is a measure of an external force required to collapse a tube with no internal force present. In a broader sense, we can define collapse pressure as the external pressure

Equation 2 is usually simplified by assuming that the tubing outer diameter is much larger than the thickness (thin-walled assumption), which results in

For compressive force, a bending stress due to buckling will be produced. The stress due to this bending varies across the tubing cross section. It reaches a maximum at the outer surface. This bending stress was originally derived by Lubinski (1962), which is

As an example, Fig. 1 shows collapse pressures based on Eq. 7

Coiled tubing is not perfectly round when it is manufactured.

2. The von Mises Criterion T he von Mises criterion is a widely accepted criterion of yielding for ductile isotropic materials. It is based on energy concepts and is also called the maximum distortion-energy theory. The criterion can be derived from the basic assumption that the distortion strain energy for combined stresses (three principle stresses) equals the maximum elastic distortion energy in simple tension. When applying to our cylinder case, its mathematical expression is:

force that causes tubing to yield in the absence of internal pressure. At collapse yield, the hoop stress is compressive with numerically negative value (see Eq. 2). The critical point of collapse yielding is always at the inner surface of the tubing. Substituting the three principle stresses (1) to (3) or (5) into (6), we obtain

Operations inside the limit curve would not yield the tube while operations on or outside the curve would yield the tube. Operators may take for a safety factor, 80% or so of calculated results as their operational criterion.

because it is physically insignificant. The yield strength collapse pressure under axial stress given by Eq. 7 is widely used and it agrees well with test data (see for example, Yang, 1995a; Bhalla, 1994; Walker and Costall, 1991; Newman, 1990; and Walker and Mason, 1990). This is the collapse pressure for perfectly round tubing. It is adopted as API standard for predicting the yield strength collapse of pipes (API Bulletin 5C3, 1994). Huang and Pattilo (1982) used deformation theory to calculate the collapse pressure of perfectly round casing pipe under tension force (compression not included), and their calculations corresponded well with the above formula.

As discussed earlier, ovality sometimes exists even before

coiled tubing is reeled onto a spool. Based on our measurements of new tubing, this ovality typically is 0.1 0.5%. After coiled tubing is manufactured, it is reeled onto a spool, and the plastic deformation due to reeling produces ovality. This ovality is affected by tubing dimensions, material grade, and reeling diameter. Additionally, this ovality usually increases as tubing is cycled. A statistical regression analysis based on measurements shows that the tubing ovality increases as the maximum strain of tubing due to bending increases (Yang, 1995b).

where

I t is well known that ovality would significantly reduce the collapse pressure of coiled tubing (see for example, McReynolds, 1982; Walker and Costall, 1991), but quantitative theories for oval tubing are not well developed. Newman (1992) made an attempt to calculate the collapse pressure based on a plastic hinge method. But the tensile yield hoop derived based on the plastic hinge assumption is always greater than the yield strength of the material for any ovality. That is physically impossible, especially at low ovality. Fowler et al. (1983) solved Timoshenko's (1961) quadratic equation for collapse pressure of oval pipe and the results agreed well with test data for casing pipes. However, their results were only restricted to pipes subjected to no axial forces. Similarly, Timoshenko's quadratic equation was interpreted with new notations in a recent paper by Avakov and Taliaferro (1995).

W e use elastic instability theory and the von Mises criterion to develop a theoretical model of collapse pressure for oval tubing. For the first time, axial forces (tension or compression) are included. Its derivations are discussed below.

by using elastic instability theory and the von Mises criterion. The solution to Eq. 14 is the collapse pressure of oval coiled tubing under tension or compressive force. Cautions should be taken in interpreting roots of this equation. Of the four possible roots to Eq. 14, the smallest of positive real roots is the solution. For example, for a tube with 3.5" OD, 0.190" wall thickness under a 20,000 lb tension load, if the material yield strength is 75,000 psi, Young's modulus is 2.9×10 7 psi, and Poisson's ratio is 0.3, then from Eq. 14, we get four roots: – 8017, 5730, 10362, and 11003. The negative root is physically insignificant, and the minimum of the three positive roots is the collapse pressure. Thus, the collapse pressure for the tube in question is 5730 psi.

tubing. A special solution for perfectly round tubing can be obtained by letting η = 0 (zero ovality) in Eq. 14. By letting σa = 0 (no axial force), the solution to Eq. 14 converges to the solution of Timoshenko's quadratic equation (see Fowler et al., 1983)

Calculations based on Eq. 14 show that increasing value of yield strength or Young's modulus increases collapse pressure. Larger tube diameter means smaller collapse pressure while thicker wall corresponds to larger collapse pressure. Fig. 3 shows the collapse pressure of a 3.5" OD and 0.190" wall thickness tube for three different ovalities shown. Again, operations inside the limit curve would not yield the tube while operations on or outside the curve would yield the tube.

tubing is sealed in the test fixture using poly-pack seals. One end is fixed by a coiled tubing clamp and the other end is connected to a 60-ton hydraulic jack. External pressure was applied to the coiled tubing in the chamber through high pressure pump line using water. Axial tension loads were

applied by the 60-ton hydraulic jack by applying a horizontal force against the fixed end. This experimental setup is similar to the one described by Walker and Mason (1990), and Walker and Costall (1991) but their tubing was placed in a vertical position and an upward tension force was applied.

V. Summary and Discussions T he collapse pressure or collapse yield is defined as the minimum pressure required to yield the tube in the absence of internal pressure. Theories of collapse pressure for perfectly round tubing have been reviewed. Based on elastic instability theory and the von Mises criterion, an analytical model for oval tubing with axial forces included is derived. Experimental data for 3.5" OD, 0.190" wall thickness tubes shows satisfactory agreement with our theoretical prediction. By letting axial forces zero, the model is used to predict collapse pressure of larger oval pipes subjected to no axial forces. The model results are in good agreement with the test data for larger pipes.

Acknowledgments I would like to express my gratitude to K. Bhalla, A. J. Dessler, W. J. Laflin, W. B. Moss, and L. W. Smith for helpful comments on the earlier draft of this paper, and to W. B. Moss for collapse tests performed at Precision Tube Technology. Special thanks go to C. Benge for providing some of the references.

Finally, we would like to point out that our model quartic equation is derived based on the maximum bending stress resulting from a second differential equation, which in turn, is based on a small-imperfection assumption of elastic instability. Hence, the model is restricted to tubes with small ovality. When the ovality becomes larger, for example, more than 5% or so, the small imperfection assumption may no longer be valid. Numerical method may be needed to solve the collapse problem for larger ovality. However, owing to the complexity of the problem and numerical accuracy, results from numerical methods tend not to agree with experimental data for small ovality but agree better when ovality increases. Therefore, a complete theory for predicting collapse pressure of coiled tubing must utilize both analytical and numerical method.

Bending Torque and Strain Energy in Reeling Coiled Tubing Yong S. Yang Precision Tube Technology, Inc. P. O. Box 24746 Houston, Texas 77229

In this paper, formulas for determining torque and strain energy in reeling coiled tubing are derived. The general formula for calculating torque is simplified by using fully plastic deformation replacing elastoplastic deformation. The simplified torque is within 0.25% relative error as compared to the torque formula obtained by using elastoplastic assumption. Most of the strain energy in reeling coiled tubing is dissipated (converted into heat). Only a small part of the total strain energy is recovered. The recovered energy is the elastic energy that is stored during reeling. The stored elastic energy typically accounts for 5% to 15% of the total strain energy in reeling, depending upon tubing and spool sizes as well as tubing material mechanical properties. Introduction Coiled tubing (CT) is a technology that is attracting a lot of attention in the oil and gas industry. Coiled tubing is a high strength, low alloy carbon steel (YoungÕs modulus ~ 29,000,000 psi and yield strength ~ 70,000 Ð 90,000 psi) tubular product manufactured in a continuos string, typically extending 3,000 to 25,000 feet in length. Traditionally, operators used pipes averaging 30 feet in length joined together section by section and supported by a derrick to service wells. With CT, a continuos length of tubing wrapped in a spool with core diameter of 240 inches or less is reeled in and out of wells like fishing line. While the average diameter of conventional drill pipe ranges from 1.625 inch to 6.625 inch, coiled tubing can be manufactured in sizes from 1 inch to 6.625 inch in diameter with wall thickness from 0.080 inch to 0.30 inch. Because of the economic advantage and operational efficiency as compared to conventional technology, CT has gained wider 1 acceptance in the oil and gas industry . Coiled tubing is manufactured in a tube mill from flat steel strip (typically 3,000 feet in length) that is rolled and welded by high frequency induction without the addition of filler metal. Coiled tubing as long as desired by users can be made by welding length of pre-inspected flat strip together prior to forming the tube in the mill. The string undergoes extensive radiographic and electromagnetic examination in both the tube and strip form. The stress induced by the mechanical deformation in the forming process is relived using an in-line full-body induction heat treatment on the mill. Sometimes tapered strings of CT (constant OD with varying wall thickness) are manufactured in order to increase the optimal performance while minimizing the total weight of the string. After the tubing is milled, it is reeled onto a spool, and hydraulically tested before it is shipped for use. Coiled tubing is now increasingly used in the oil and gas industry. Safety and reliability are the major concerns for the coiled tubing operators. There are many factors that

determine the life of a given CT: corrosion; flexural bending; internal (or external) pressure and tension (or compression); and mechanical damage due to improper use. While 2 fatigue, collapse, and buckling problems are well studied , the basic mechanical properties such as bending torque and strain energy are less documented. The understanding of the bending torque is important in choosing the spool sizes as well as reeling motors. The understanding of the strain energy, especially the recoverable elastic energy, is important for safety in using coiled tubing. In this paper, we derive formulas for determining bending torque and strain energy in reeling coiled tubing. Our calculations show that the plastic bending moment accounts more than 99% of the total bending torque in reeling coiled tubing. The elastic bending moment is less than 1% of the total bending torque. Thus, one can safely treat the bending of coiled tubing in a typical core or guide arch as perfectly plastic deformation. Most of the strain energy in reeling coiled tubing is dissipated, but the stored elastic energy is significant, constituting about 10% or so of the total strain energy, depending on the tubing sizes, core or guide arch dimensions, and mechanical properties. Bending Torque Required in Reeling Coiled Tubing Denote Mb as the torque for bending a tube into a circular arc with radius R (reeling radius). For simplicity and without loss of generality, we assume that the tubing is an ideal plastic material with an elastic region; its stress-strain relation is shown in Fig. 1.

In the following derivations, we assume dy Ç di/2. Generally, dy is small (only a few percent of the outer diameter); therefore, this assumption is justified. With the elasticplastic boundary determined, the torque can be obtained through an integration. The integration is performed in polar coordinates (see Fig. 2). The result is3 y σy r dr dθ +

This is the result one can get by assuming that the tubing is a rigid, ideal plastic material (K. Newman, private communications, 1995). The validity of the rigid, ideal plastic assumption is shown in Table 1 by comparing torque calculations using Eq. 2 and Eq. 3 for several tubing sizes and spool diameters. The differencebetween Eqs. 2 and 3 is quite small, with relative error within 0.25%. Therefore, the simple torque formula (Eq. 3) is an excellent approximation. It can be used as the solution for determining the bending torque required for reeling coiled tubing. Strain Energy in Reeling Coiled Tubing Generally, the strain energy density at any level is the area under the stress-strain curve below that stress level. The strain energy density represented by the total area under the complete stress-strain curve is associated with the total strain energy density ε

Again, we assume that the tubing is an elastoplastic material. The effectof residual stress is neglected, which greatly simplifies the computation. Fig. 3 shows the behavior of a tubing under uniaxial stress. The tubing has been loaded beyond the elastic limit and then unloaded. Some of the total energy absorbed is recovered; the remainder is dissipated (converted into heat). The recovered energy is the elastic energy that was stored during the action. The total strain energy (UT) consists of elastic strain energy (recoverable) (Ue) and plastic strain energy (dissipated into heat) (Ud). For a tubing with outer radius ro, wall thickness t, and length L reeling into an arc radius R, the total strain energy (the required work) is

In reeling coiled tubing, the plastic bending moment accounts more than 99% of the total bending torque. The elastic bending moment is less than 1% of the total bending torque. Hence, we can safely treat the bending as perfectly plastic deformation. Although most of the strain energy in reeling coiled tubing is dissipated, the stored elastic energy is significant, constituting about 5% to 15% of the total strain energy, depending on the tubing dimensions and mechanical properties. In our calculations, we assume that the tubing is an elastoplastic material. This is a valid assumption based on stress-strain tests of our tubing. Experience shows that CT does not typically work harden. We did not take work-hardening effectinto consideration; however, when work-hardening of the material is considered, we do not expect significant changes in our results.

General Guidelines for Coiled Tubing Radiography Following are recommended guidelines for performing radiographic examination of circumferential butt welds in downhole grade carbon steel coiled tubing. It is strongly recommended that all shots are made using an X-ray tube with variable kV and MA outputs on industrial grade, extra fine grain, high contrast film (such as Fuji 50 or Kodak M) with lead intensifying screens. Gamma-rays (such as Iridium 192) should be used only on the understanding that apart from geometric considerations, the flaw sensitivity will be inferior to that of a good X-ray technique. Also, insure that personnel performing these examinations are qualified and certified in accordance with ASNT Recommended Practice SNT-TC-1A or equivalent standards. In order to obtain maximum flaw sensitivity, the tubing surface should be of suitable condition to a degree that surface irregularities (such as weld ripples or grinding marks) cannot mask or be confused with discontinuities in the weld itself. Weld surface irregularities on the OD should be sanded or filed down flush or left with a reasonably uniform crown. Quality and sensitivity of the radiographs is determined using either wire or hole-type image quality indicators.. The proper IQI for the thickness of the specimen being examined should be capable of showing an image quality level of 2-2T, or equivalent sensitivity, in accordance with ASME Group

1 IQI’s. PTT uses a no. 7 penetrameter with a 2-T hole for the most common sizes. Another indicator of radiograph quality is the geometric unsharpness. This factor is related to the size of the source of radiation and its magnitude depends on the effective source dimensions and the relative distances of source-toobject and object-to-film. The unsharpness formula is intended for guidance on technique Final acceptance of radiographs should be based on the ability to see the prescribed IQI image and the specified hole or wire; however, IQI’s are not intended for use in judging size nor establishing acceptance limits of discontinuities. For circumferential butt welds in tubing diameters up to 3-1/2”, use a double wall technique, double wall viewing in which the radiation passes through two walls and the weld in both walls is reviewed for acceptance on the same radiograph. An IQI should be used on the source side only with the radiation beam offset from the plane of the weld at an angle sufficient to separate the images of the weld so that there is no overlap of the areas to be interpreted. To obtain complete coverage, a minimum of Source

two (2) exposures taken 90° to each other should be made (see Figure 1). In addition to elliptical exposures, the weld must be radiographed with the radiation beam positioned so that the images of both walls are superimposed.

HS-90™ GRADE COILED TUBING - NORTH SEA SERVICE IN H2S ENVIRONMENTS History and Testing of Coiled Tubing for Sour Service: Precision Tube Technology has had SSC tests conducted on its 70 ksi and 80 ksi minimum yield strength grades in both transverse and longitudinal directions in NACE TM0177 tests - no cracking or failures were detected at 100% of the specified minimum yield strength. SSC tests were also conducted after the coiled tubing was subjected to 10 and 100 cycles of coiling and uncoiling (cold working). In these same TM0177 tests which utilize atmosphere pressure of H2S (1 bar) at very low pH values (about 3.0), no cracks or failures were detected at 100% of the specified minimum yield strength. These results indicate that the materials and condition of coiled tubing does not degrade unacceptably

Our researchers predict that HS-90™ Grade coiled tubing will exhibit a threshold stress of 100% of the specified minimum yield strength in severe North Sea environments, for example, 0.1 atm H2S in low pH (about 3.5) environments. This same threshold would be expected to be in the 80% - 90% range of the specified minimum yield strength in NACE TM0177 type environments. - RB
