1. Introduction 1.1 Drilling The Agitator gently oscillates the BHA or drillstring to substantially reduce friction. This means improved weight transfer and reduced stick-slip in all modes of drilling, but especially when oriented drilling with a steerable motor. As well profiles become more tortuous and the limits of extended reach boundaries are explored, the Agitator provides a simple means of expanding the operating window of conventional steerable motor assemblies. Smooth weight transfer and exceptional tool face control is now possible with PDC bits, even in significantly depleted formations after large azimuth changes. Extended intervals can be achieved and the lack of requirement to work the BHA - to obtain and maintain tool face - provides significant ROP improvements. The Agitator is compatible with all MWD systems and provides a viable means of extending long reach targets while improving ROP, reducing roller cone bit runs and minimizing the chance of differential sticking. MWD/LWD Compatibility • Does not damage MWD tools or corrupt signals • Reduces lateral and torsional vibration • Run above or below MWD • No impact force to bit or tubulars Bit Friendly • Can be used with roller cone bit or fixed cutter bits • No impact forces to damage teeth or bearings • Extends PDC life through controlled weight transfer; no spudding Directional Enhancement • Prevents weight stacking and allows excellent tool face control • Provides means of sliding at increased ROP and lower weight off hook • Allows weight transfer with less drill pipe compression

AGITATOR

The Agitator allows steerable motors to expand the boundaries of extended reach drilling, and enhances their efficiency in less complex applications. 1.2 Intervention and Coiled Tubing Friction also plagues intervention work. The Agitator has been used to convey memory logs, perforating guns and to slide stuck tubing sleeves at the end of tortuous completion strings. It has also proven beneficial in running liners and in the retrieval of stuck assemblies. Note: Please contact NOV for up to date information.

2. How it Works The Agitator system relies on three main mechanisms: 1. Power section 2. Valve and bearing section 3. Excitation section: • Running on jointed pipe = use a shock tool • Running on coiled tubing = coiled tubing does the shock tool’s job

AGITATOR

The power section drives the valve section producing pressure pulses which in turn activate the shock tool or act on the coiled tubing. It is the axial motion of the shock tool or coiled tubing which breaks static friction. The unique valve system is the heart of the tool; it converts the energy available from the pumped fluid into a series of pressure fluctuations (pressure pulses). This is done by creating cyclical restrictions through the use of a pair of valve plates. The valve opens and closes with the result that the total flow area (TFA) of the tool cycles from maximum to minimum. At minimum TFA, the pressure is high and at maximum TFA, the pressure is low. (See Fig. 3)

P (psi)

P = pressure drop across valve plates t = time 1. Valve moves to one extremity TFA minimized = pressure peak t (sec)

P (psi) 2. Valve moves to center TFA maximized = pressure trough t (sec)

P (psi)

3. Valve moves to other extremity TFA minimized = pressure peak

t (sec) Fig. 3. Relative positions of valve plates 5

How It Works The frequency of these pressure pulses is directionally proportional to the flow rate. Refer to the tool specifications to see the frequency/flow rate relationship for each tool size. The size of the valve plates is configured based on operational parameters to optimize performance and ensure that the pressure drop is always within specification. The Agitator itself only creates pressure pulses. In order to transform this hydraulic energy into a useful mechanical force in jointed pipe operations, a shock tool is placed above the Agitator tool in the BHA or drill string as in Fig 2. In coiled tubing operations only the Agitator is required; the coiled tubing expands and contracts as the pressure pulses act on it. The shock tool contains a sealed mandrel which is spring loaded axially, (see Fig. 4). When internal pressure is applied to the shock tool the mandrel will extend due to pressure acting on the sealing area (also known as the pump open area) within the tool. If the pressure is removed, the springs return the mandrel to its original position. When used directly above the Agitator, the pressure pulses cause the shock tool to extend and retract, thus producing an axial oscillation. The Agitator system may be positioned anywhere in the drillstring to focus energy where it will be most effective. Agitator System - Overview • The Agitator System consists of a power section which drives a valve • The valve creates pressure pulses. Their frequency is directly proportional to the flow rate • Shock Tool: A shock tool converts pressure pulses into axial movement (in coiled tubing applications a shock tool is not required)

3. Planning The Job 3.1 Operating Parameters Customers are requested to complete a simple Agitator prejob check sheet to ensure that the tool is set-up correctly, including: • Flow rate • Fluid weight and type (See section 3.2) • Pressure drop available to the Agitator • Downhole temperature • Inclination and azimuth • Drilling/intervention plan and/or well type • Planned BHA configuration The valve plates will be selected based upon flow rate, fluid weight and pressure drop available to the Agitator. The flow rate and mud weight ranges should be kept as accurate as possible to aid best tool set-up. Hydraulics software is used to aid tool set-up and produce an operating chart for the job. 3.2 Drilling/Completion Fluids Drilling/completion fluids information is required to ensure that the power section elastomer and the rotor will be compatible with the operating environment: • Brand and manufacturer • Type/composition • Chlorides concentration • PH level • Mud – oil/water ratio (%) • MSDS sheets for all completion fluids and additives Downhole operating temperatures will also influence choice of power section. 3.3 MWD The Agitator is compatible with all MWD systems. Pre-job planning is advised to avoid any problems at the rig site, however. Where the MWD frequency can be altered please contact NOV for advice. Also see Section 7.1 for Agitator frequency information. 8

AGITATOR 4. Applications 4.1 Drilling Applications Applications and tool positioning: • Above motor, below MWD • Above motor and MWD • Vertical rotary assembly • Andergauge adjustable stabilizer assembly • Up hole on drill pipe (See 4.3 Optimization Service) • Dual Agitator assembly (See 4.3 Optimization Service) • TTRD • Coiled Tubing drilling 4.2 Non-Drilling Applications • Coiled Tubing Intervention: - Extended reach - Stimulation - Manipulation - Scale/fill removal - Logging • Fishing • Running liners • Cementing 4.3 Optimization Service If provided with full well information, NOV can provide an optimization service to ensure that the placement of the Agitator is optimized for jointed pipe operations. • Torque and drag analysis • Determine effective friction factors

5. Drilling Procedures (Jointed Pipe) 5.1 Surface Testing • Make up the tool in the BHA; do not grip on stator body whilst making up. • For BHA placement in jointed pipe applications the Agitator will normally be positioned between the mud motor and the MWD system. (see 4. Applications and 5.3 Tool Positioning). • The shock tool is placed directly above the Agitator main body. (See Fig 5) • The Agitator and shock tool may be tested on surface to test the movement of the shock tool. • The Agitator frequency is directly proportional to flow rate. During the surface test, strong rig vibrations may be apparent. If this is the case, it may be necessary to test with a lower flow rate. At lower flow rates the movement on the shock tool will be reduced. • Movement should be seen at the top of the shock tool during the surface test. Movement is generally in the range 8” - a” (3 – 10 mm). If there is very little weight below the shock tool, movement may not commence until a reasonable flow rate has been achieved. Cold Climates Testing The tool should not be surface tested if the temperature is below 14ºF (-10ºC). There is a high risk of damaging the elastomer. Hot Hole Tools Testing The power section will be fitted with a relaxed interference fit to ensure correct performance under hot conditions. On surface (lower temperatures) the elastomer will not swell and a higher then specified pressure drop will be experienced. Note: Contact NOV for Operating Procedures relating to coiled tubing drilling and intervention operations.

Drilling Procedures 5.2 Testing with MWD Systems Check with the MWD Field Engineers whether they will be testing just to see pulses (Pulse Only Test), a more comprehensive test (Full MWD Test), or if they will test the MWD 656 – 984 ft (200 – 300 m) downhole (Shallow Hole MWD Testing). Pulse Only Test (at Surface) This can be done with the Agitator in the BHA. Test the flow rate required by the MWD (this should be more than sufficient to activate the Agitator system). There will be easily recognizable oscillations in the BHA. If the shock tool is visible, there will be an obvious 8” - a” (3–10 mm) axial movement. Full MWD Test (at Surface) NOV recommends testing the Agitator separately from the MWD string. Once the test has been successfully completed, the Agitator can then be picked up and tested. Bring the pumps up steadily until vibrations can be felt, or movement seen in the shock-tool. There is no need to pump at full drilling rate for the Agitator test. As soon as vibrations are seen, the test is successful and the pumps can be turned off. Shallow Hole MWD Testing Where an MWD test is to be done at a depth of typically 656 – 984 ft (200 – 300 m), NOV recommends the Agitator and motor are tested at surface, as above. The MWD string can then be picked up and run into the hole for a normal test. There is no minimum duration for testing – if vibration is seen, then the test is good. Additional confirmation can be seen on the MWD Operator’s pulse detection screen.

AGITATOR

5.3 Advice While Drilling Weight on Bit The Agitator can be more effective at overcoming weight stacking problems when lower WOB is used. With a higher WOB the springs in the shock tool are compressed, reducing the effectiveness of the Agitator. In low inclination wells ensure that the shock tool is in compression and avoid bit bounce. Tool Positioning In highly tortuous well designs, or where it can be proven that weight stacking is occurring further up the hole, it may be beneficial to run the Agitator system higher in the drill string. Please contact your local NOV office for further assistance. Operational Effectiveness The optimum effectiveness of the tool depends on mud flow rate. The tool will have been specifically configured for the job in hand and should be run at its optimum flow rate for maximum performance. The tool will be more aggressive at higher flow rates. The “Pre-Job Check Sheet” will contain drilling parameters specific to your job. Note: Check with your local NOV office if there will be significant changes in drilling parameters.

13

5.4 Tool Storage and Handling Cold Climate Storage Guidelines Stators should be stored in an environment above 32°F (0°C). Short duration below freezing will be unavoidable when transporting to the field or on stand-by but long term storage should be above 32°F (0°C). Assembled tools should not be stored in temperatures below 14ºF (-10ºC) for periods exceeding one week. Hot Climate Storage Guidelines Stators should not be stored in direct sunlight. Cover tools with a tarp if stored outdoors. Post-Job Handling Flush tool with clean water first then apply a soapy solution, e.g. washing-up liquid. The Agitator’s power section cannot be rotated by external force; hang tool vertically (pin connection down); pour solution in the top (box connection) and allow to filter down through the power section. Alternatively, pump fresh water though the tool.

14

AGITATOR 6. Trouble Shooting 6.1 Tool Operation Recognizing How the Tool is Working If the Agitator is under-performing then the following factors should be considered: • Mud weight and flow rate vs. planned: Check these parameters against the operating chart. • BHA position – reposition the Agitator or add a second tool (See 4.3 Optimization Service) • Temperature and mud type: actual vs. planned • Hours in hole • LCM pumped – Agitator has same capabilities as a drilling motor. Elastomer Over Shakers More than likely to be the drilling motor. The Agitator power section is not required to generate torque therefore is less stressed and less likely to fail. The Agitator power section is a 1:2 lobe style section whereas most motors are multilobe. (See Fig. 6) Therefore close observation of the elastomer pieces should reveal whether it is the Agitator or a multilobe molding.

Trouble Shooting Using the MWD Oscilloscope to Monitor Agitator Frequency The Agitator’s frequency can be monitored on the MWD oscilloscope (See Fig 7). Normally a spike will be apparent at the Agitator’s operating frequency which verifies tool operation. Fig.7 shows spike at approx. 17 Hz. The operating frequency can vary by up to 2Hz from tool to tool so do not be alarmed if the frequency is not exactly as calculated. Changes in temperature can also affect the tool frequency.

Signal Loss The Agitator will still be operating even if a signal reduction or loss is experienced. This is not unusual, and only if accompanied by a large pressure change should there be cause for concern. Signal loss is likely to be caused by: • Harmonics • Attenuation Often the signal will return through time/depth if caused by harmonics. If down due to attenuation then the signal will generally decrease with depth (See Fig 8).
