4.1

18-5/8” CASING PHASE

4.1.1 SETTING 20-3/4" CASING HEAD HOUSING x 18-5/8” SLIPLOCK (SEE DRAWING SD-010245-04-10) 1.

Run the conductor and casing as required

2.

Determine the correct elevation for the Casing Head and cut conductor pipe as required. Ensure conductor pipe is level and the cut is smooth.

3.

Cement as per Customer procedure. Note : Cut the conductor pipe low enough to allow access to the slip retainer screws when the head and its landing base are installed.

4.

Rough cut the casing approximately 24” above the top of the conductor (or a minimum of 8” above the anticipated final cut height).

5.

Install landing base on top of conductor.

6.

Examine the 20-3/4” 3M x 18-5/8” Sliplock Casing Head Verify the following : o ring groove, casing hanger seal area, and casing seal area are clean and undamaged, o bore is free of grease and dirt, o all peripheral equipment is intact and undamaged,

7.

Orient Casing Head with Sliplock connection down.

8.

Final cut the casing at the measured pocket depth (minus 12.7mm ½”) above the top of the conductor. Bevel top of the casing stub and remove all burrs sharp edges.

9.

Wipe the ID of the ‘P’ seals of the Casing Head and the OD of the casing stub with light oil and grease.

10. Suspend the Casing Head above the casing stub, ensuring that it is level and orienting the outlets to be compatible with drilling equipment 11. Carefully lower the Casing Head over the Casing Stub until the Head lands on the Casing Stub 12. Remove the slip retaining screws once the casing is properly landed. Ensure that the slips settle evenly and are not cocked in the slip bowl. 13. Energize the ‘P’ seals following dedicated procedure. And test between, to 80% of casing collapse pressure. 14. Once testing is complete, tighten the nuts of the slib bowl in an alternating cross pattern to the determined torque.

4.2

13-3/8" CASING PHASE

4.2.1 TESTING BOP'S (SEE DRAWING SD-010245-04-11) 1.

Inspect top gasket preparation of casing head housing, clean with diesel, and remove small scratches with fine emery paper. Install a ring gasket type RX-74 P/N 702002-07-42.

2.

Nipple up B.O.P. stack on 20-3/4”API 3000 R-74 casing head housing flange.

3.

Check that all locking screws (2) are fully retracted

4.

Make up the 20” Nominal Combination Tool P/N 238875-16-01-02 on a drill string (NC50) pins facing up.

5.

Run the combination tool through the BOP's and land in casing head housing.

6.

Close rams on drill string and test BOP's through the kill line (3000 PSI or 80% of the collapse resistance of the running string used, whichever is less).

7.

Bleed pressure.

8.

Open rams

9.

Retrieve the combination tool.

4.2.3 SETTING 13-3/8" CASING HANGER (‘S-BOWL’) (SEE DRAWING SD-010245-04-13) 1. Run 13-3/8" casing 2. Make sure there is no collar in a 13" (330mm) area on the casing below the Housing top. This condition must be verified either with casing tension or not. If there is casing coupling in this area casing hanger cannot be set, so pull casing string enough to clear the area from coupling. 3. Open outlet valves on housing. 4. Circulate and cement as per Customer program. 5. After cement has been confirmed lift-up BOP's above the Housing. 6. Centralize casing as closely as possible to set properly. 7.

NOTE : Packing must not be compressed, i.e., does not extend beyond OD of top hanger. If so slightly loosen cap screws at hanger top (the lower plate should be snug to slightly loose)

SEE RP 554 for DEDICATED RUNNING PROCEDURE

9. Make a rough cut of 13-3/8" casing approximately 14" (350mm) over 20-3/4" housing flange face. 10. Remove casing pup. Then, remove BOP's. 11. Final cut 13-3/8" casing at 183 ±1.5mm (7.2"±0.12") above 20-3/4" housing flange face. Make the cut as level as possible.
