Description The ‘Hydro-6’ is a compact, economical, single string hydraulic set retrievable packer ideal for use in deviated wells, multiple packer completions and applications where the packer(s) is to be set after the well is flanged up. Since no mandrel movement occurs during setting, the Hydro-6 may be used in single packer installations, or as the lower packer in multiple zone dual completions. It is also ideal for multiple packer single string completions. The Hydro-6 is available in a wireline controlled selective set version if required. The Hydro-6 design features a unique system that allows debris to be circulated from above the packer when releasing.

Features and Benefits •

No tubing movement required to set the packer.

•

4.0 Handling, Storage & Make-Up Guidelines

5.0 Running Instructions

shear screws for a maximum tension to release of 50,000 pounds. Install a tubing plugging device as specified in the well program. This could be a pumpout plug or wireline nipple with a plug or any other device used to plug the tubing string. The shear value of a pump-out plug must be greater than the minimum differential pressure required to achieve minimum pack-off as shown in Table A.

Prior to running the tool(s) in the hole, determine:

Warning:

4.0 Handling, Storage & Make-Up Guidelines Detailed handling instructions applicable to all Schlumberger Completion Systems products are found in the required supplemental manual Handling, Storage & Make-Up Guidelines, manual number SM001.

a. Setting Shear Pressure (psi) b. Tension to Release

Warning:

The packer is designed to set in response to tubing to annulus pressure differential. When setting in low fluid level wells, do not fill the tubing while running in the hole, the differential hydrostatic pressure may prematurely set the tool.

The ‘tension to release’ is the amount of tension in pounds that must be pulled on the tubing to shear the shear screws (26) (5,000 pounds each) in-stalled in the lower cone and release the tool. This amount of tension is based on well conditions and operating parameters. Make certain the amount of tension to release does not exceed the strength of the tubing string. The packers can be dressed with up to 10 Operating Manual

6.0 To Release Packer To release the packer, simply pick up until the preset tension to release value is exceeded. The mandrel is pressure balanced to annulus pressure above the tool, (with the same size tubing) so annulus pressure will not affect release force. After shear screws release the mandrel, the mandrel moves up exposing circulation/equalization ports that may be used for circulation before coming out of the hole. Pull the first stand slowly to allow the elements and slips to properly relax. After the packer is fully released, tool may be tripped out of the hole. Note: In order to prevent accidental release, the correct number of shear screws (26) should be installed even if the rotational release is to be used. 7.0 Disassembly Procedures 1. Place tool in vise gripping on lower portion of the main mandrel (2) above the bottom coupling (27). Note: As the tool is disassembled, remove and discard all o-rings. 2. Remove top coupling (1). 3. Remove set screws (19) from slip cage (23). 4. Remove shear screws (26) from lower cone (24).

Schlumberger Private

The shear setting pressure is the amount of differential pressure in favor of the tubing at the setting depth of the tool(s) that is required to shear the shear screws (7) (2,000 pounds shear value each) installed in the top gauge cap and piston/upper cone and begin the setting process. The shear setting pressure is determined by the downhole conditions and the operating parameters of the well. It is recommended that there always be one more shear screw installed in the top gauge cap than is installed in the piston/upper cone. This will insure that the slips are engaged before the packing elements begin to extrude. The packer mandrel may be pressure tested up to 70% of the setting shear pressure from Table A without risk of shearing the shear screws (7), installed in the piston/upper cone.

Ensure that the pressure required to shear the screws in the top gauge cap is not greater than the pressure rating of the tubing or greater than the pressure required to shear the pumpout plug.

7.0 Disassembly Procedures 5. Disengage lower cone (24) from lock mandrel (6). Drive lower cone (along with the complete outer shell of the packer) downward with a soft metal bar until it releases from the collet. 6. Slide the packer body subassembly (complete assembly from top gauge cap to collet) off the top of the main mandrel (2). Set aside. 7. Remove bottom coupling (27) from main mandrel (2). Take main mandrel (2) out of vise and remove lower cone (24) from main mandrel (2). 8. Remove slip cage (23) with slips (22) and slip springs (21) from piston/upper cone (17).

10. Loosen upper gauge ring (28) to expose shear screws (7). (This step applies to 6-5/8” and larger sizes only.) 11. Remove brass shear screws (7) from top gauge cap (4). 12. Remove top gauge cap (4) from lock mandrel (6). 13. Pull spacer ring (11), end packing element (9), and center packing element (10) off of packing element mandrel (8). 14. Place backup wrench on ratchet cylinder (12) as close as possible to the gauge ring. Place wrench jaws over shear screw groove in the packing element mandrel (8) and un-thread the packing element mandrel (8) . 15. Place backup on piston/upper cone (17). Remove packing element mandrel (8) by unthreading off of the lock ring (18). 16. Remove snap ring (15). 17. Using spreader pliers, remove lock ring (18). The lock ring should be inspected for damage such as pulled threads, scaring, corrosion, etc.

20. Move in vise to make certain vise jaws are griping on lock mandrel (6) and not on the lock mandrel (6). Place wrench jaws on lock mandrel (6), just above slots and remove from lock mandrel (6). 8.0 Assembly Procedures 1. Install all o-rings in the respective grooves except the outer o-ring (16) for the piston/upper cone (17). Use ample grease when assembling the tool. Place lock mandrel (6) in vise. Thread on lock mandrel (6) and tighten. 3. Slide piston/upper cone (17) onto lock mandrel (6) until the piston/upper cone is past the snap ring groove on the lock mandrel. 4. Install snap ring (15) onto lock mandrel (6). This locks the piston/upper cone (17) in place on the lock mandrel (6). 5. Slide piston/upper cone (17) upward until it shoulders on snap ring (15). Line up shear screw holes in piston/upper cone (17) with shear screw groove in lock mandrel (6) and install brass shear screws (7). 6. Using spreader pliers install lock ring (18) onto piston/upper cone (17). Blank end of lock ring (18) shoulders against the edge of the upper cone. 7. Install outer o-ring (16) in o-ring groove on piston/upper cone (17). 8. Coat the fine threads on the piston/upper cone (17) with ample grease. Slide packing element mandrel (8) onto piston/upper cone (17) and thread ratchet cylinder onto the lock ring. Make

18. Remove the brass shear screws (7) from piston/upper cone (17).

8.0 Assembly Procedures certain the lock ring does not move or begin to ratchet as the ratchet cylinder is threaded. Friction from the o-ring can cause the lock ring to ratchet as the ratchet cylinder is threaded. Gently tap the end of the ratchet cylinder with a rubber hammer while threading the ratchet cylinder onto the lock ring. Thread ratchet cylinder onto lock ring until all threads on the lock ring are covered by the ratchet cylinder.

15. Tighten guide ring (30) onto lower cone (24).(This step applies to 6-5/8” and larger sizes only.)

9. Thread lower gauge ring (29) onto packing element mandrel (8) and tighten. (This step applies to 6-5/8” and larger sizes only.)

18. Slide the packer body subassembly onto the main mandrel (2), lock mandrel (6) first. Push the subassembly onto the main mandrel until it shoulders. In this position you can see the bypass holes in the main mandrel above the top gauge cap.

11. Tighten top gauge cap (4) onto lock mandrel (6) and install shear screws (7). When top gauge cap is tight, the shear screw holes in the top gauge cap will line up with shear screw groove in the packing element mandrel (8). If the holes do not line up, the alignment of the lock ring is wrong and must be redone. Note: For 6-5/8” and larger sizes, thread upper gauge ring (28) onto top gauge cap (4). Leave upper gauge ring (28) loose until shear screws (7) have been installed in top gauge cap. 12. Remove this assembly (packer body subassembly) from the vise and stand upright on top gauge cap (4). 13. Insert slip (22) with slip spring (21) into window in slip cage (23). Insert 10-24 UNF screw through hole in slip cage and thread into the hole in the center of slip. The 10-24 screw will hold the slip and slip spring in place in the window of the slip cage. Repeat until all slips and slip springs are installed. 14. Slide the slip cage (23) with slips and slip springs over the lock mandrel (6). Align slots in the slip cage with the screw holes in the piston/upper cone (17) and install set screws (19). Operating Manual

17. Grease entire main mandrel.

19. Snap the lower cone (24) over the lock mandrel (6) with enough force to engage the fingers of the collet into the lower cone. Slide the lower cone and the packer body subassembly upward until the lower cone shoulders on the main mandrel. The shear screw holes in the lower cone will line up with spot-faced holes on the main mandrel. If collet and lower cone are properly engaged, the lower cone will spin freely and the top gauge cap will cover the bypass holes in the main mandrel. 20. Install retaining screws (19) through slots in slip cage (23) into holes in lower cone (24). Remove 10-24 UNF screws holding slips in place. 21. Line up shear screw holes in lower cone (24) with spot faced holes in main mandrel (2) and install shear screws (26). Note: For tools with 'secondary rotational release', align shear screw holes in lower cone (24) with spot faced holes in shear sleeve (26). 22. Install top coupling #1. Tighten through top coupling to make up both top coupling and bottom coupling (27) onto the main mandrel (2).

9.0 Instructions to Change Setting Shear Value on the Hydro-6 Packer 9.0 Instructions to Change Setting Shear Value on the Hydro-6 Packer 1. Determine appropriate number of shear screws from Table A. 2. Secure top or bottom connection in vise. 3. Loosen upper gauge ring (28) from top cap (4). (This step applies to 6-5/8” and larger sizes only). 4. Remove or add shear screws (7) as required. Slightly loosen remaining shear screws without disengaging screws from shear groove. Schlumberger Private

5. Remove retaining screws (19) from top of slip cage (23) and slide slip cage down as far as possible. 6. Rotate packing element mandrel (8) and lock ring (18) together to access shear screws (7) through split in lock ring (18). Note: It is critical to rotate 'cylinder' portion of element mandrel and locking ring together to prevent 'binding' of lock ring. (Packing element mandrel, elements and top gauge cap will all rotate together and upper shear screws must remain in the groove to maintain orientation of lock ring. 7. Remove or add shear screws (7) as required. 8. Install retaining screws (19) in slip cage (23). Tighten shear screws (7) in top gauge cap (4). 9. Tighten upper gauge ring (28).
