Commission Anchora i.~ MEMORANDUM TO: David Joh~ Chairmah ~ State of Alaska Alaska Oil and Gas Conservation Commission DATE: February 23,1995 THRU: Blair Wondzell, ~ FILE NO: P. I. Supervisor ~e.a FROM: .s~~"~ SUBJECT: Bobby Fo ' Petroleum Inspector PH91BWCD.doc Perforation Cmt. Plug BPX- PBU - C-25 Prudhoe Bay Field Thursday, February 23, 1995: I traveled this date to BPX's well C-25 after being contacted by Jerry Bixby, BPX's wireline supervisior, requesting that witness the tagging and pressure test of the cement plug set to cover the existing perforations in preperation to side track this well. i went to Jerry's office and discussed the job with him. Jerry said he was sorry for such short notice on the job but the temperature had risen enough - from -44 to -40 degrees - that he could rig a wire line unit up but he could not get a pump truck to pressure up on the plug. I agreed to tag the plug and pressure the plug up when a pump truck was avialable. I went to the well and the wireline unit had rigged up and was going in the hole. The calculated top of the cement was 9,500', WLM, and we tagged the cement at 9,398' or 102' high which presented no problem with the AOGCC regulations concerning plugging of perforations. This plug covered the open perferations from 10,313, to 10,270' and the previously squeezed perforations from 10,270' to 10,068' plus 670' up inside the tubing which puts the top of the cement 168' below the 9.625" x 5.5~ packer set at 9,230' Friday, February 24, 1995: I returned to well C-25 this morning and witnessed the pressure test of the 5.5" tubing. The tubing was pressured up to 1580 psig and held for 30 minutes with a 40 psig pressure loss. ! informed the BPX rep., Lee Hinkle, that the plug was acceptiable and departed the location. Summary: ! witnessed the pressure test and tagging of the acceptiable perforation plug on BPX's PBU well C-25.

Dear Mr, Reil~y: Enclosed is the approved application for permit to drill the above referenced wall, Well samples and a mud log are not required. A continuous directional survey is required as per 20 AAC 25.050(b)(5). If available, a tape containing the digitized log information shall be submitted on all logs for copying except experimental logs, velocity surveys and dlpmeter surveys. Many rivers in Alaska and their drainage systeas have been classified as important for the spawning or migration of anadromous fish. Operations in these areas are subject to AS 16.05,870 and the regulations promulgated thereunder (Title 5, Alaska Administrative Code). Prior to commencing operations you may be contacted by the Habitat Coordinator's Office, Department of Fish and Game, Pollution of any waterm of the State is prohibited by AS 46, Chapter 3, Article 7 and the regulation~ promulgated thereunder (Title !8, Alaska Administrative Code, Chapter 70) and by the Federal Water Pollution Control Act, am amended. Prior to commencing operations you may be contacted by a representative of the ~epartm~nt of Environmemtal Conservation. To aid us in scheduling field work, pleame notify this office 24 hourm prior to commencing installation of th~ blowout prevention equipment so ~hat a representative of the Commissiom may be present to witnemm testing of the equipment before the Mr. R.
