Supervisor ~"f~'ff~¢ FROM: Lou Gdmaldi~,~-c SUBJECT: Petroleum Inspector DATE: July 15, 1995 FILE NO: AINJGOCD.DOC BOP test Nabors dg #18-E BPX well #U-15 Prudhoe Bay Field PTD # 95-78 Saturday, July 15, 1995: I witnessed the weekly test of the B©PE on Nabors dg #18-E which was ddlling BPX well #U-15 in the Prudhoe Bay Field. The BOP test was started at 2330 hrs of the previous night and lasted approximately 4.5 hours. All equipment functioned and held propedy with'the exception of the IBOPPThe dg was in good shape and the crew seemed well acquainted with proper BOP test procedure. The H2S detectorsC~were tested and would not tdgger when the sample gas was applied. The methane detector,,~ould not be tested due to lack of sample gas. The area surrounding the dg was clean and ordedy providing good access to the dg. SUMMARY: I witnessed the weekly BOP test on Nabors dg #18-E ddlling BPX well #U-15. Test time 3.5 hours, 2 failures.

This well was 'plugged back due to less than expected oil column in the Sadierochit Formation. The well will be sidetracked to a new bottom hole location. We tagged the cement plug at 9,480 feet, with 20,000 pounds of drillstring weight. The top of the Sadierochit Formation is at 10,405 feet MD. A balanced kick off cement plug will be laid from 3,336' to 2,936 for the sidetrack. This plug will be +/- 100' inside the 10 314" casing.

The drilling fluid program and surface system will conform to the regulations set forth in 20AAC25.003. b. Maximum surface pressure is based on BHP and a full column of gas to TD (0.10 psi/f-t). c. Based on previous logs on U Pad, no hydrocarbon zones are anticipated above the Sag River. d. No potential hazardous levels of H2S are anticipated in this well. e. Drilling hazards: · Previous wells have experienced losses into a small sand at around 4500' TVD. The sand is believed to be discontinuous with a small capacity and losses have cured themselves. · The Cretaceous may be affected by GC2 injection and overpressures of up to 150 psi are possible at around 4600' TVD.

THE REPEAT AND MAIN LOG WERE LOGGED AT 30 FEET/MINUTE UP TO 9800', THEN THE SPEED WAS INCREASED. THE ACOUSTIC DATA SHOWS CYCLE SKIPS. PER CLIENT'S REQUEST, BOREHOLE & TORNADO CHART CORREC- TIONS WERE APPLIED TO THE DIL DATA. THE DIL DATA WAS CORRECTED FOR BOREHOLE SIZE (9.875"). THE CORRECTED DATA WAS THEN USED IN THE ATLAS TORNADO CHART TO GET "RT" & "DI" CURVES. RT = TRUE FORMATION RESISTIVITY. DI = DEPTH OF INVASION.
