Under the authority of Conservation Order 341, Rule 5, these wells are not required to have fail-safe automatic SSSVs. However, the LPSs and SSVs must be maintained in good condition and, if for any reason, the wells again become capable of unassisted flow of hydrocarbons, the SSSVs must be reinstalled and maintained in good working condition.

The wells were tested using the American 425 gas measurement meter used previously in the field. There were 5 wells to be tested, but only 2 were tested. Wells R-9, 21, and~would not bleed down, so only wells R-8 and 17 were tested. The crew began bleeding the wells on R pad down in the afternoon of 12-18-94. The bleed down of the Y pad wells began in the afternoon of 12-19-94. The bleed down on the X pad wells began on the after noon of 12-20-94. The gas meter was tied into tubing at the swab cap on each well and a reading was taken approximately every hour for 3 hours with the following results: WELL R - 08 Casing pressure - 240 psig Tubing pressQre -0 psig Water Cut -65.2% Test # 1 - 6 sd/hr.

Nabors rig #18-E was on the well and had expierienced some problems with thier first attempt at placing this plug. When I arrived the rig had already circulated out the old contaminated cement and laid a new batch in place over the retainer. The rig was standing by for cure time to tag the plug. We tripped in the hole and tagged the top of cement at 8538' with the retainer reportedly set at 8650'. The rig then set down 25,000 pounds on the plug, which appeared firm and did not move. the fluid was then changed out from 10.1 mud to 8.6 seawater and the casing and plug was then pressure tested to 3000 PSI for 15 minutes with no loss observed SUMMARY; I witnessed verification of the placement of a casing shoe plug in BPX well U-1 lA in the prudhoe bay field Attachment ' CINJGNAB.XLS Operator: Operator Rep.: Lease No.: Drive Pipe: Conductor: Intermediate: STATE OF ALASKA ALASKA OIL AND GAS CONSER VA TION COMMISSION Plug And Abandonment Report BPX CRAIG HURST Well No.: U-11A Sec.

Returnea Commissioner SUBMIY IN 'I'I~IPLICATE Form 10-403 Rev 06/15/88 A,-,Co Alaska, BP EXPLORATION To: AOGCC Commissioner Date: July 13, 1993 From: Ding Hsu Tel: 564-5061 Subject: Plugginq for Temporarily Suspension for U-11A Sidetrack well U-1 lA will be temporarily suspended due to severe loss circulation problem in the Shublik formation. Severe lost circulation and 25' of missing Shublik indicate that we crossed a fault at or near the top of the Ivishak. That being the case, it was not desirable having a Zone 4 frac'd producer so close to a fault. The rig (Nabors 18E) will move to drill new well U-14 and sidetrack U-04Ai, which will give us time to evaluate the new bottom hole location to redrill. The following is a proposed plugging program to meet the requirements of AOGCC regulation 20 AAC 25.105. In addition, we like to request for an exception to 20 AAC 25.105 (c) to waive the requirement of setting a surface plug for U-1 lA temporarily suspension.. Recommended Pluaaina and Suspension Proaram: (1) Contact AOGCC representative to discuss and witness the program for temporary suspending well U-1 lA. (2) RIH with 5" open-ended drilipipe to TD. Break circulation and condition the mud before going into open hole. (3) Circulate and condition mud at TD (10,384'MD) until hole stabilized. (4) Lay a 47 bbls of balance cement plug from TD (10,384'MD) to 500'MD above top of Sag River formation (9719'MD). Pump 50 bbls of water ahead of cement plug and appropriate water spacer behind to balance the cement plug. (5) POOH into the 9-5/8" shoe.

This sidetrack wellbore will be drilling through majority of Kingak shale section and may cross a small fault (25'-50') in the lower Jurassic interval. Drilling may encounter loss circulation and/or hole stability problem in the Kingak interval. Well U-11 is currently producing at 470 BOPD at a 1500 GOR and 90% watercut. The current well is fault-cut in the Shublik and has suffered from high watercut production for much of its life. Post-sidetrack production rates are estimated at 1200 BOPD at 20% WC and 1000 GOR pre-frac, with a post frac rate of 3000 BOPD, 25% WC and 1000 GOR. The well will be completed with 4.5" 13Cr tubing and 7" 13er/L-80 liner. The well will be fracture stimulated, therefore, a good primary liner cement job and an anchor type of tubing packer are required for this well. SCOPE: The original wellbore will be plugged and abandoned prior to the sidetrack using coiled tubing, and the wellbore will be pre-cut using a chemical cutter. Pull the existing 4-1/2" 12.6# L-80 BTC tubing completion. Mill a section in the 9-5/8" casing and lay a cement plug below and across the section. Kick-off and drill a new 8- I/2" hole to TD of 150' MD below the prognosed top of HOT Run wireline conveyed open hole logs. Cement in a 7" 29# L-80/13Cr liner. Recomplete with 4-1/2" 13Cr tubing with approximately 5 gas lift mandrels. TIMING: This U-1 lA sidetrack is presently scheduled for Nabors Rig 18E upon completion of activity on U-7A sidetrack program in Mid July, 1993. The sidetrack should take approximately 18 days.

Pre-rig work: Kill well. Lay cement plug across perforations to at least 100' MD above top perforation. Cut 4-1/2" tubing just above the packer SBR. Freeze protect and set a BPV. Test intermediate casing pack-off to 3500 psi. Move in drilling rig. Test 9-5/8" intermediate casing pack-off if not done during pre- rig work. Pull BPV. Circulate diesel freeze protection cap from well and recover for future use if feasible. Set a BPV and remove the production tree. Install BOP's and test to 5000 psi. Remove the BPV. Pull and lay down the existing 4-1/2" tubing. Run 9-5/8" casing corrosion Icg (Schlumberger USIT) only if intermediate casing integrity is suspect. Set a 9-5/8" bridge at 9050'MD (300' below the bottom of section window). Replace the 9-5/8" casing pack-off as needed. Spot a 18 ppg pill on bottom and cut a 50' section in the 9-5/8" casing from about 8700' to 8750' MD. Spot a balanced cement kick-off plug (165 cubic feet minimum) from 100' below the base of the section to 200' above the top of the section. Run in with an 8-1/2" steerable drilling assembly and dress the cement to 5' below the section top. Kickoff and directionally drill to align well with target. Follow with an 8-1/2" packed hole assembly and drill to the target at 150' MD below the HOT of- 10840'MD/9106q'VDss (see directional plan for more details). Run wireline conveyed open hole (GR/DIL/BHCS/CNL) logs. If a DLL is used in place of the DIL, a micro-resistivity Icg will be required. Run a 7" 29 # L-80 / 13Cr liner assembly to bottom in the 8-1/2" hole. Space the liner hanger and top isolation packer about 150' up inside the 9-5/8" casing. The top of 7" liner is at 8550'MD). Cement the liner in place with the total cement volume based upon 60 % open- hole enlargement plus the shoe volume, lap volume and 150' excess on top of the liner with drillpipe in the hole. Re-test the 9-5/8" casing pack-off and replace as needed. Clean out the liner to the landing collar and test to 3500 psi. Displace well to filtered and inhibited seawater. Run a 4-1/2" 13CR completion string and 7" packer. Space out, land tubing hanger and set packer. The packer should be set at about 10069'MD (150' above Sag River) with the tubing tail above any future objective. Test tubing to 4000 psi. Test tubing by casing annulus to 3500 psi. Set two-way check valve. Remove BOP's. Install and test the production tree to 5000 psi with diesel. Pull the two-way check valve. Shear RP valve in the upper GLM and freeze protect the well. Set a BPV. Release workover rig. Complete appropriate documentation and hand-over to Production for pedoration. Run cement bond Icg and possible Gyro if BHL in question after released the rig.
