HYDRA-SHOCK® Model B Tool Operation & Service Manual
SECTION 1 General Description During drilling operations, various dynamic impact loads are imparted from the drill bit to the drill string. These loads, which are cyclical in nature, may lead to many problems: • Premature failure of the drill string and rig equipment • Low penetration rates • Hole problems The HYDRA-SHOCK® Model B tool is designed to absorb and dampen the variable axial dynamic loads produced by a drill bit during “normal” drilling operations. Unlike other tools on the market, the HYDRASHOCK® Model B tool is fully compensated for both pump pressure, which has a tendency to open the tool, and hydrostatic pressure, which has a tendency to close the tool. Consequently, as dynamic impact loads are transferred from the bit to the drill string, the tool, which is in a hydraulically “neutral” position, readily dampens the loads without the additional task of overcoming any pressure differentials. Additionally, the tool’s stroke length and low spring rate make it active over a much greater range of operation. As a result, the penetration rate and bit life are greatly improved. As axial loads are produced, energy absorption is accomplished through the use of a spring element; force dampening is accomplished through the use of fluid and mechanical friction; and pressure compensation is accomplished through the use of a fluid transfer system. These three elements are the “heart” of the tool.

HYDRA-SHOCK® Model B Tool Operation & Service Manual
SECTION 1
Operation As a tri-cone bit rotates, it produces a pattern on the bottom of the borehole which consists of “peaks and valleys”. With each revolution of the bit, the cones will tend to follow the sinusoidal contour of the bottom of the borehole producing a cyclical oscillation of the drill string. The springs in the HYDRA-SHOCK® Model B tool, normally used to keep the tool extended, are compressed and absorb the shock load produced by the bit cones as they progress through one of the “peaks”. Additionally, the load is dissipated by fluid friction created when oil is metered through the spring stack and by mechanical friction resulting from the movement of the spring stack. When the bit cones move into a “valley”, the HYDRA-SHOCK® Model B tool’s springs will extend the tool to its normal position. These two combined actions isolate the axial loads present during the drilling operation and maintain a near constant weighton-bit when the tool is run within its operational load limits. Maximum shock absorption is achieved by placing the HYDRA-SHOCK® Model B tool as close to the bit as possible. Care should be taken to ensure that the tool is never run in the neutral zone, in tension, or in oversized boreholes (hole sizes greater than 2 times the OD of the tool). The engineering specifications for the HYDRA-SHOCK® Model B tool can be found in Table 1. Table 1 Engineering Specifications (metric)

Change Out Recommendations
Change Out Recommendations The HYDRA-SHOCK should be changed out, periodically, for servicing. See Table 2, Change Out Recommendations, to determine recommended hours of use before servicing. Follow the step below to use the information in Table 2, Change Out Recommendations. Step 1. Select the Tool OD. Step 2. Determine the drilling USAGE. Step 3. Select the hole size and note the corresponding hours. Step 4. Determine the bottom hole temperature and note the corresponding hours. Step 5. Compare the hours between the temperature and the drilling USAGE. Step 6. The smaller of the two will determine the service period.

HYDRA-SHOCK® Model B Tool Operation & Service Manual
SECTION 1
Placement The HYDRA-SHOCK® Model B Tool is most effective when placed directly above the bit. Like other vibration dampeners, the HYDRASHOCK® Model B tool is less stiff than a drill collar of the same OD. Depending on the placement of the tool, the reduced stiffness can compromise the performance of the bottom hole assembly. Also, if improperly placed in the bottom hole assembly, high stresses could reduce tool performance and life. General guidelines for tool placement are as follows: • In a slick bottom hole assembly, place the tool above the bit, as shown in FIG. 1. • For a pendulum assembly used in very mild crooked tendencies, the tool can be placed directly above the bit, as shown in FIG. 2. • For pendulum assemblies used where there are crooked hole tendencies, it is recommended that the tool be placed directly above the first (fulcrum) stabilizer, as shown in FIG. 3. In addition, a second stabilizer should be placed one drill collar up from the tool. This will help reduce stresses in the tool due to lateral loads. • In packed bottom hole assemblies, it is recommended that the tool be placed above the second zone of stabilization, as shown in FIG. 4. Avoid using the tool as a short drill collar since the reduced stiffness will compromise bottom hole assembly performance and increase bending stresses in the tool. • When crooked hole tendencies are severe, it is recommended that the tool be placed above the third zone of stabilization, as shown in FIG. 5. It is also recommended that an additional stabilizer be placed one drill collar above tool to reduce lateral loading.

SECTION 2
Thread Galling Cautions Galling can be caused by: • Dirty or damaged threads and/or thread shoulders. • Threads and shoulders that are not completely covered with thread lubricant before assembly. • Misaligned connections during assembly or disassembly. • Applying a bending load when torquing the connection during assembly or disassembly. • Leakage which would allow the connection to become dry or filled with abrasive matter. Steps to prevent galling: • Clean and dry connection threads and shoulders thoroughly. • Apply thread lubricant evenly over threads and shoulders. • Position the backup device and breakout device as shown in disassembly and assembly sections. • Support and tie down the appropriate parts with a hold down steady rest as described in Disassembly and Assembly. • Torque connection properly, to the recommended make-up torque. To Break A Stuck Connection Tap the outside surface of the connection with a hammer while slowly unscrewing the part. It may be helpful to work the connection out by alternately tightening and untightening the part several times, FIG. 7. If such methods fail, one part of the connection can sometimes be machined away in an attempt to salvage the other. Ultimately, the connection can be forced apart. This may scrap both parts. Sub

Inspection Procedures
Springs
a. Twenty-five percent of the springs should be subjected to magnetic particle inspection (MPI). During the MPI, the coils should be positioned such that the inspector can check for cracks propagating circumferentially on the I.D. and O.D. surfaces as well as for cracks propagating radially from the I.D. of the part towards the O.D. of the part. If cracks or other improprieties are found in one (1) spring, all springs in the spring stack shall be subjected to MPI testing. b. Springs that have cracks or other improprieties should be discarded. c. Measure 25% of the springs, to determine if there are any changes in overall height. Height variations greater than those specified in Table 3 found in one (1) spring shall necessitate the measurement of all springs. Table 3 Tool O.D. 6-3/4 (171) 8-1/2 (216) 11-1/4 (286)

Seal Assembly Procedures
Seal Assembly Procedures Seal Description The HE Group “SUPER SEAL” is a composite type of material with each seal element performing a specific function. • The SNE Ring is forced down the gland taper to close the shaft to gland clearance as pressure is applied to the Major Seal. Closure of the SNE Ring prevents extrusion of the SSR Ring and Major Seal. • The SSR, made of glass-filled Teflon, not only acts as a spacer between the Major Seal and SNE Ring, but polishes and conditions the chrome and/or colmonoy shaft as it reciprocates under pressure. • The Major Seal, the resilient seal member, must hold both low and high pressure. The Major Seal is double-acting when a tapered seal groove is provided as shown in the illustration below. A Rod Wiper, positioned forward of the SUPER SEALS and PolyPak, prevents grease, mud and debris from entering. Seal Inspection Inspect all seals (O-rings, SNE’s, SSR’s, Major Seals, PolyPaks and Rod Wipers) after steam cleaning. If any seal appears worn or cracked, replace it. Seal must be absolutely clean to reuse
