It is planned to perforate the well from 5050' - 5060', 600' below the existing SV1 perforations at 4130'- 4220'; 4406' - 4430' and the old squeeze perfs at 4448' - 4450'. A baseline Temperature / GR log will be run prior to perforating. Following perforating, 150 degree produced water will be injected into the lower perforations for 24 hours. Another Temperature / GR log will then be run to detect any channeling to the old perforations. If channeling is found, the lower perforations will be squeezed with cement and the injection and the logging procedures repeated. A maximum of two cement squeezes will possibly be performed on the lower perforations. The injection and logging procedures will be performed after each squeeze. Following the work on the lower perforations, the old squeeze perforations at 4448' - 4450' will be isolated from the lower perforations and the injection and logging procedures will be repeated. If isolation can not be achieved at any of these points, the well will be plug and abandoned. If isolation can be established, one last cement squeeze will be performed on the upper perforations at 4130'- 4220'. The well will then be completed with a 5-1/2" tubing straddle assembly covering the interval from 4000' - 4500' and 7" tubing to surface. The procedure below outlines the three injection /logging tests and two cement squeezes at the lower perforations, the injection tests at the old squeeze perforations, one cement squeeze at the upper perforations, and completing the well with a straddle assembly.

I told him our plans were to do an injectivity test down the 9-5/8" x 13-3/8" annulus to determine if we could arctic pack the 13-3/8" annulus. Also we are evaluating the possibility of squeezing the well. AOGCC RESPONSE: Verbal response to go ahead with diagnostic work. Sundry Notice Req'd at this time?

HH. 75.1 TELEPHONE NO: SUBJECT: Injection Well Problems AAI PBU DW PW 1-2 Permit No. 90-33 Pruhdoe Oil Pool Haroid R. HawKins Petroleum Inspector, Friday June 29, 1990: I called Lonnie Smith with AOGCC and he ihfo~ed me ~hai~the injection well AAI PRU PW DW 1-2, had a problem and to check it out. I did. The well is now disconnected from the injection source and is shut down. Pressures on well are zero. I checked the pad around the well. You could see where water had flooded on the pad but no hydrocarbons were present on or in the gravel. Production took over well after I witnessed and passed mech integrity tests. Two were performed and passed. This was not where the problem was. The problem seems to be a bad cement job on 9 5/8 casing. When injection was started, it came up around 9 5/8 and then up around and away from the 13 3/8 and 20" and outside the cellar to the surface. I was told by Steve Massey and James Fausett that this was the drilling department's problem and should never have been turned over to production to inject when they knew there was a problem with the cement bonding to the 9 5/8 casing. In summary, the problem was not the MIT tests, it was the long string of 9 5/8 incorrectly cemented in the first place. 02-00lA (Rev. 6/89) 20/ll/MEMO1.PM3 STATE OF ALASKA ALASF .)ILAND GAS CONSERVATION (' VlMISSION APPLICATION FOR SUNDRY A PROVALS 1.

Test casing to 2500 psi for 30 minutes. 4. Pick up 12-1/4" BHA and GIH. Drill 10 ft of new hole and perform leakoff test. 5. Ddll a straight 12-1/4" hole to 6600' TVD/MD. 6. Run wireline logs as programmed. 7. Run 9-5/8" casing and displace cement with brine. 8. Test casing to 3000 psi for 30 minutes. 9. Release drilling rig. Run cased hole logs 7 days after rig release. 10. MI and RU completion rig. Run 7" tubing and packer assembly. Test tubing casing annulus to 3000 psi for 30minutes. Notify the AOGCC so a representative can witness the casing integrity test. 11. N/U 7" tree and test to 3000 psi. Release completion rig. 12. Rig up wireline unit and perforate. NOTE; a. The 13-3/8" x 9-5/8" annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sx of cement followed by Artic Pack. b. No existing wells are within 200 ft. of the proposed well. c. The drilling fluid program and surface system will conform to the regulations set forth in 20AAC25.033. d. Maximum surface pressure is based on BHP and a full column of gas to TD (0.10 psi/fi). e. Based on the logs from PWDW 1-1, no potential productive zones are anticipated above 3000' TVD. f. No potential hazardous levels of H2S are anticipated in this well. RECEIVED MAR - 1 1990 Alaska Oil l Gas Cons.
