Go' f;01,Sw Alston 333 West 7 Avenue Anchorage, Alaska 99501 4 "14' *Je p' _ Subject: Corrosion Inhibitor Treatments of GPB Y Pad 1 Dear Mr. Maunder, Enclosed please find multiple copies of a spreadsheet with a list of wells from Y Pad that were treated with corrosion inhibitor in the surface casing by conductor annulus. The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Jerry Murphy, at 659 -5102.

The well was vented to an atmosperic tank thru a 2" line prior to my arrival. The tubing was then connected to the American AL-425 gas meter with 1" hose. The well was monitored every 1/2 hr. for 1 1/2 hrs. and did not exceed more than 10 scl/hr. Therefore I recommend that No-Flow status be granted to Y-28 at this time.

Grimaldi Petroleum Inspector SUBJECT: RIG BOPE Inspection BPX Well #Y-28 Prudhoe Bay Unit Permit No. 91-65 Drilling May 19, .1991: I performed a RIG/BOPE Inspection on AUDI Rig #3 drilling well #Y-28 in the Prudhoe Bay Unit for BPX. I found all equipment on the rig to be operating satisfactorily and the location, although very muddy, to be kept as clean and orderly as possible. It is in my opinion that Wayne Fisher and Jack Boehler (AUDI toolpushers) strive to keep this rig and its equipment in the best shape possible. In summary: AUDI Rig #3 is in good shape for drilling well #Y-28.

As the attached AOGCC BOPE Walk-thru inspection report indicates, I found all items in compliance. There had been a non-compliance item on the last walk-thru inspection made by Louis Grimaldi. There was a 45 degree turn in the choke line running from the stack to the choke manifold. This has been replaced with two targeted tee'sand straight pipe. In summary, I conducted a BOPE Walk-thru inspection at BPX PBU Y-28 well on AUDI Rig No. 3, I found all items in compliance. Attachment. 02-00lA (Rev. 6/89) 20/11LMEMO1.PM3 .

The Drilling fluid program will consist of an 8.5-9.5 ppg spud mud in the 13-1/2" hole, a 9-9.8 ppg water base mud in the 9-7/8" hole and a 8.9 ppg water base mud in the 6-3/4" hole. Drill 13-1/2" hole to 2700' MD and cement 10-3/4" 45# L-80 Buttress casing to surface. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annula~ preventer. Maximum possible bottomhole pressure is 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss and an oil column to 8800' TVDss. Directionally drill 9-7/8" hole to the 7-5/8" casing point at the top of Sag River formation. Run 7-5/8" 29.7# L~80 NSCC casing to within 10' of 9-7/8" TD and cement with Class G cement around the 7-5/8" shoe. The annulus will be freeze protected by dry crude. Directional drill 6-3/4" hole to TD. Run 5-1/2" Chrome liner from TD to 250' inside 7-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" landing collar. Change over to NaCL completion fluid. Test casing and lap to 3000 psi. Run 7-5/8" production packer on chrome tubing. Set packer 50' above top of liner. A subsurface safety valve'-'W'it"~ dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree. Displace tubing to diesel. Set and test packer. The well will be perforated after rig release. Fluids incidental to the drilling of a well will be pumped down the 7-5/8" x 10-3/4" annulus of the well.
