I witnessed the verification of a welibore plug in BPX Well M-26. This plug had been laid in by coil tubing on April 18, 1992. Verification consisted of tagging top of cement with electricline, which then cut the tubing and pulled out of hole. The tubing and annulus were then pressured to 2000 psi and held for 15 minutes with no loss of pressure observed. In summary, I witnessed verification of a wellbore plug in BPX Well M-26.

Notify an AOGCC representative prior to commencing operations. 2. Rig up coiled tubing unit. 3. RIH with coil tubing circulating seawater. Lay a cement plug from +11,510' to 10,884' MD (50' below the bottom perforation -- bottom perforation at 11,460' MD to at least 100' above the top perforation -- top perforation at 10,984' MD). 4. RU slickline unit. RIH and confirm cement top at least 100' above top perforations. Note: Tag to be witnessed by AOGCC representative. 5. RU E-line and make a tubing cut at +/-9850' MD based on completion tubing tally. 6. Circulate well over to seawater and freeze protect well to 2000'. 6. Bleed tubing, inner annulus, and outer annulus to 0 psi. 7. Set 6-3/8" BPV and prepare Pad for RWO. 8o MIRU rig. Pull BPV. Circulate out freeze protection. Pull 5-1/2" tubing. 9. RIH with a 9-5/8" bridge plug and set at 9830' MD. Test w/ 15,000#'s of pipe weight. A kick-off plug will be set after milling the window. The base of this kick-off cement plug will be at 9730' MD (100' below the window). Note: Steps #9 and 10 are a variance of state regulation 20 ACC 25.105(h)(2) on the placement of a liner top cement. Although the liner top plug is higher above the liner top than as specified in the regulations, an bridge plug, a weight test of the bridge plug, and 100' of cement on the kickoff plug is believed to be a competent plugback.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Where a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe.

Install 20" diverter. The Drilling fluid program will consist of an 8.5 - 9.5 ppg spud mud in the 17- 1/2" hole, a 9.0 - 9.7 ppg water base mud in the 12-1/4" hole and a 8.6 ppg water base mud in the 8-1/2" hole. Drill 17-1/2" hole to 2700' TVD (BKB) and cement 13-3/8" L-80 Buttress casing to surface. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 3710 psi at 8800' TVD(SS) based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVD(SS) and an oil column to 8800' TVD(SS). Kick off at 3000' TVD (BKB) and directionally drill 12-1/4" hole to the 9-5/8" casing point above the Sag River Sandstone. Run 9-5/8" 47# L-80 NSCC casing to within 5' of 12-1/4" TD and cement with Class G cement around the 9-5/8" shoe. The annulus will be freeze protected by dry crude. Directionally drill 8-1/2" hole to TD. Run 7" liner from TD to 250' inside 9-5/8" casing shoe and cement using Class G cement. Clean out to 7" float equipment. Change over to NaC1 completion fluid. Test casing and lap to 3000 psi. Run 9-5/8" production packer on tubing. Set packer 50' above top of liner. A subsurface safety valve with dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree with diesel. Displace tubing to diesel. Set and test packer. Move rig off. Run GR/CLL/CBT/CET/GYRO and perforate with rig off. Fluids incidental to the drilling of a well will be pumped down to the 9-5/8" x 13-3/8" annulus of the well.
