Hydra-Thrust™ Tool Operation & Service Manual
SECTION 1 General Description The Houston Engineers, Inc. Hydra-Thrust™ tool provides constant weight on the drill bit. This constant weight allows the rate of penetration to be maintained and lowers the risk of stalling the downhole motor. The Hydra-Thrust tool is located in the lower drilling assembly. As the bit weight drills off, pump force opens the tool. At the same time, as pump pressure decreases, weight from above causes the tool to close. The combination of opening and closing the Hydra-Thrust tool will maintain a constant weight on the bit. As a result of advances in shaft seals and mechanical improvements, the Hydra-Thrust tool is an excellent drilling tool to counteract rigorous drilling requirements such as: • High temperatures • High-drilling torque • Long-term use The tool parts are made from high quality steel with a heat treatment process that provides the best high strength and fatigue resistant properties. Special hard trim and plating processes are used to condition and recondition wear surfaces, to assure long term use.

Hydra-Thrust™ Tool Operation & Service Manual
SECTION 1
Placement Several factors are considered when determining the placement for the Hydra-Thrust Tool. They are: • Pressure available at the Hydra-Thrust Tool. • Extension force of the Hydra-Thrust Tool. • Buoyed weight of the bottom hole assembly. • Desired weight on bit.
Placement in Vertical or Deviated Wells The extension force of the tool plus the buoyed weight of the BHA below the tool shown equal the desired weight on bit. Place the remaining BHA above the tool. The buoyed weight in compression above the Hydra-Thrust tool must be greater than the extension force of the tool.
Placement in Horizontal Wells Place close to the bit. The buoyed weight in compression above the Hydra-Thrust tool must be greater than the extension force of the tool.
Function/Drill Off Test To insure proper operation of the Hydra-Thrust tool, the following test should be performed: 1. With the pumps off, slowly lower the BHA to contact the bottom of the hole. 2. Slack off to the desired WOB, set the brake, and mark the kelly. 3. With the brake set, engage the pumps and begin rotation. Maintain pumps and rotation at normal speeds for sufficient time to drill off no more than two feet at previously established penetration rate. 4. Stop rotation and disengage pumps, release brake and slack off again to desired WOB. Mark the kelly again. 5. Pick up the string and measure the distance between marks. The differential between the marks indicate the Hydra-Thrust Tool is operating properly.

Operation
Operation After tagging bottom; 1. Set brake. 2. Engage pumps. 3. Begin rotation. • As the bit drills ahead, the pump will force the tool open, in order to maintain constant weight on bit. 4. Slack off on brake to keep the predetermined weight to bit. • As weight is applied, the tool will close, in order to maintain constant weight on bit.

SECTION 2
Thread Galling Cautions Galling can be caused by: • Threads and/or shoulders that are dirty or damaged. • Threads and shoulders that are not completely covered with thread lubricant before assembly. • Misalignment of the connection 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: • Position the tong and vise close to the connection • Support and tie down the breakout parts with a hold down steady rest as described in disassembly and assembly.
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 back-up and unscrew the part several times to work the connection out, see FIG. 2. 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 with the power tong. This may scrap both parts.

SECTION 4 Inspection Procedures Inspection should occur as soon as possible after tool is used in the hole. Replace parts that do not comply to an acceptable condition. No machining or reworking is to be performed without Houston Engineers' approval.
Cleaning Procedures 1 Water soak tool parts to remove dried, caked mud. 2 Use steam and a strong biodegradable cleaner to remove oil and grease. 3 Allow steam cleaned parts to dry and cool before inspection tool.
Rework The pin and box rotary shouldered connection (RSC) threads should be reworked to the Houston Engineers, Inc. Specification Manual (Drilling and Fishing Tools Rotary Shouldered Connection section).
Inspection Procedures Inspection procedures will meet the applicable content of API RP 7G, Section 12. Check all parts for wear, cracks, rust and deformation as follows: • All internal and external connections should be subjected to magnetic particle inspection each time the tool is disassembled. • Fill plug holes should be subjected to magnetic particle inspection each time the tool is disassembled. • Check all external parts for wear down as listed in Table 2. When the O.D. wears down to the diameters listed the part is scrap. • Use Critical Parts Inspection form, page 23, for rejection criteria to denote condition of parts. • Wear cannot be eccentric in nature. Use the Part Inspection Guideline on page 20-22.

SECTION 4
Seal Assembly Procedures Seal Description The HE “SUPER SEAL” has been developed to withstand 20,000 PSI and up to 500°F for acceptable periods of time. These Seals are the heart of the hydraulic principle of jarring. Primary and secondary seal systems have been designed into the tools to guard against premature failure in the detent oil systems. The HE “SUPER SEAL” is a composite type of Seal with each separate element performing a specific function. The split bronze\ 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 Shaft Seal Retainer is made of glass filled Teflon and 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 is the resilient seal member and 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 is positioned forward of the SUPER SEALS to prevent grease, mud and debris from entering.
Seal Inspection All seals (O-rings, SNE’s, SSR’s, Major Seals and Rod Wipers) should be inspected after steam cleaning. If any seal appears worn or cracked, it should automatically be replaced. Otherwise, if any seal is to be reused, it must be absolutely clean.

Seal Assembly Procedures
Seal Assembly Procedures Seals may be assembled into all designated parts before assembly of the tool or they may be assembled as designated parts are assembled. The exact order must be followed for each part. Kelly Mandrel Step 1. Assemble one Hycar O-ring over the pin threads and into the O-ring groove.
Drive Cylinder Step 1. Assemble two SSR Rings into the deepest seal groove first. SSR Rings may become deformed and bent, but do not break or cut. Straighten out in groove after insertion. Step 2. Push both SSR Rings to either the up or down side of the groove. Rings should fit snug and stay in selected position when pushed to one side of the groove. Step 3. Assemble SNE Ring (three sections) and hold together against the bevel of the groove with the SSR Rings. SNE Ring may be held in position with a heavy grease. Step 4. Assemble second SNE Ring (three sections) against the opposite side of the groove and hold in place with the SSR Ring. This will leave a space between the SSR Rings. All Rings should stay in place. If not, remove all Rings and slightly stretch all the SSR Rings, but do not break. Reassemble as in Steps 1, 2 and 3. Step 5. Assemble the Major Seal in between the separated SSR Rings. Fold the Major Seal in a U shape and insert into the seal groove. Relax the Seal into place. Step 6. Assemble the Rod Wiper into the outer most seal groove. Fold the Rod Wiper into a U shape and snap the seal into place. Step 7. Assemble one Hycar O-ring over the pin threaded connection of the Cylinder and into the O-ring groove, where required.
Drive Pin Retainer Sub, Connector Sub, & Lower Sub Step 1. Assemble one Hycar O-ring over the pin threads and into the O-ring groove.

SECTION 4
Knocker Step 1. Assemble one Hycar and Teflon O-ring up against the back of both internal seal grooves. Note the O-ring order in both seal grooves. Proper sized O-rings must be correctly assembled. Step 2. Assemble another Teflon and Hycar O-ring into both seal grooves. Note the O-ring order in both seal grooves. Use proper sized O-rings.
Step 3. Assemble one Teflon O-ring in the largest seal groove up against the Hycar O-ring. Note that this arrangement only applies to the larger seal groove. Step 4. Assemble one Hycar O-ring into the seal groove nearest the face of the Knocker.
Balance Piston Step 1. Fold the Major Seal in a U shape and snap the seal into the internal seal groove. Relax the Seal into place. Step 2. Assemble Major Seal over O.D. of Balance Piston and into the external seal groove.
