Supervisor'-" FROM: Chuck Scheve; SUBJECT: Petroleum Inspector DATE: May 7, 2001 Safety Valve Tests Prudhoe Bay Unit Drill Site 12 Monday, May 7, 200!: I traveled to BPXs Drill Site 12 and witnessed the semi annual safety valve system testing. As the attached AOGCC Safety Valve System Test Report indicates I witnessed the testing of 21 wells and 42 components with 1 failure. Thesurface safety valve on well 12-12 had a slow leak when pressure tested. This valve was serviced and retested by the operator on this date. Bill Preston (lead DS operator) performed the testing today; he demonstrated good test procedures and was a pleasure to work with. A walk through inspection of the well houses on this pad was performed during the SVS testing with no problems noted. All well houses inspected were reasonably clean and all equipment appeared to be in good condition. Su..mma. ry.: I witnessed the semi annual SVS testing at BPXs Drill Site 12.

If available, a tape containin~ t'he digitized log information shall be submitted on all logs for copying except experimental logs, velocity surveys and dipmeter .surveys. Many rivers in Alaska and their drainage systems have been classified as important for the spawning or migration of anadromous fish, Operations in these areas are subject to AS 16.50.870 and the regulations promul~ated tl~ereunder (Title 5, Alaska Administrative Code). Prior to com~enein~ operations you may be contacted by the Habitat Coordinator~s office, Department of ~ish and Game. Pollution of any waters of the State is prohibited by AS 46, Chapter 3, Article ? and the re~tlations promul~ted thereunder (Title 15, Alaska Administrative Code, Chapter ?0) and by the Federal Water Pollution Control Act, as amended. Prior to Charles E. Ross Prudhoe Bay Unit DS 12-4A -2- December 17. 1981 e0mmeneing operations you may be contacted by a representative of the Department of Environmental Conservation. To aid us in scheduling field work, we would appreciate your notifying this office within 48 hours after the well is spudded. We would also like to be notified so that a repre- sentative of the Commission may be present to witness testing of blowout preventer equipment before surface casinll shoe is dril led.

Rochon District Operations Engineer December 2, 1981 Mr. Lonnie Smith State of Alaska Oil & Gas Conservation Comm. 3001 Porcupine Drive Anchorage, Alaska 99504 Dear Mr. Smith' i~FILF: As you know, we have requested approval for sidetracking wells 12-4 and 12-7 because of water channels behind the casing in these wells and because of our limited success in shutting off water by workovers in similar wells. Wellbore schematics showing perforations and oil- water contacts are attached' for' your information. The existence of these channels is supported by the histories of the wells since per- forating. The histories follow: D.S. 12-4 Well 12-4 was perforated in March, 1980. Intervals perforated were 10173'-10230' and 10258'-10296'. Samples taken during clean-up of the well showed the water cut increasing from 50 to'65%. A static gradient survey indicated water in the wellbore. The wellbore and flowline were displaced with diesel for freeze protection and the well was left shut-in. In June 1980 a production logging program was completed on this well. The cement bond log indicates poor cement down to 10510'(The oil-water contact is at 10396'). The spinner flowmeter shows no flow below the perforation. The tempera- ture log indicates channeling behind the pipe from about 10430' to the perforations at 10296'. The Prudhoe Bay Operation report for March, 1980 showed 5396 STB of oil produced by thi.s well. Thi. s volume was in:. error ~because production was allocated based on engineering production estimates rather than actual well tests. This error was not noticed at the time the report was submitted. D.S. 12-7 Well 12-7 was perforated in May, 1980. Intervals perforated were 10431 '-10465' and 10479'-10545'. Initially no water was produced. However, after about two weeks of production the water-cut rose dramatically, the well was displaced with diesel for freeze protec- tion and shut-in. A production logging program was completed in June, 1980. The cement bond log shows inadequate bonding above about 10830'(The oil-water contact is at 10663'). The spinner flowmeter ARCO Alaska, Inc. is a subsidiary of AtlanticRichfieldCompany RECEIVED Nada 011 & Gas Cons. Commission Anchorage Mr. Lonn~" Smith DecemberS, 1981 Page 2 shows no flow below the perforations. The temperature log indicates channeling from about 10760' to the perforations at 10545'. This information should confirm the water channeling behind pipe and allow for approval of the sidetracking. If you have any further questions on this matter please contact me at 263-4246.
