Obp GL-~AF To: Winton Aubert - AOGCC Date: June 23, 2006 From: Ken Allen - BPXA GPB Rotary Drilling Subject: Z-14B Application for Sundry Approval- P&A for Sidetrack Operations Approval is requested for the proposed P&A of PBU well Z-14A. This well is currently shut in due to low / injectivity performance. The wellbore is currently providing no benefit to the field. The proposed work will utilize pre-rig coil tubing to place a cement plug across the existing perforations in the 2-7/8" CTD liner. This will isolate and abandon the Ivishak formation completion in Z-14A. Addition isolation will come from a bridge plug in 9-5/8" below the new rotary drilled sidetrack and cement between the 9-5/8" and new 7"/ casing in the liner lap. The proposed rotary high angle sidetrack will target the Zone 4, 3 and 2 reserves for additional injection support. Z-14B is planned to place a slant sidetrack across Zones 4, 3 and 2 below a new 7" drilling liner. / Both liners will be fully cemented in place and pressure tested. This well may be pre-produced if sufficient oil column is found before starting injection. The Z-14B sidetrack is currently scheduled for Nabors 7ES beginning around JUI~~, 4, 006. The pre-rig work for this sidetrack will be priority scheduled after the Application for Sundry is ~~~d. Scope Pre-RiCl Work: 1. Rig up slickline. Pull PX plug from TP. Drift 4-1/2" x 2-7/8" tubing.

P.O. Box 196612 Anchorage, AK 99519-6612 6,~'q - Cd l O~ Dear Mr. Yeager: On July 20, 2001, BP Exploration (Alaska), Inc. ("BPXA") filed an Application for Sundry Approval (10-403) to convert the Pmdhoe Bay Unit Z-14A well from an oil producer to an injector. It appears from our records that the application to convert the Z- 14A well to an injector was never approved by the Commission. In an August 21, 2002 e-mail to Tom Maunder at the Commission, you indicated BPXA had no plans to convert this well to an injector and that the sundry should be cancelled. However, our records indicate that BPXA reported monthly injection from this well for the month of September 2001 and filed a Report of Sundry Well Operations for the conversion of the Z-14A well from a producer to an injector on October 22, 2001. Since the Commission records appear to indicate that this well was converted to an injector, we would appreciate BP.XA checking its records and verifying the stares of this well. In addition, please provide the Commission with an analysis of the future utility of this well. If you have any questions regarding this matter, please contact Winton Aubert at 793- 1231.

Well Z-14A was drilled in March of 1998 as a high angle coiled tubing sidetrack. Logs showed very little oil column, and the well produced for less than 6 months. It has remained shut-in since October of 1998. As part of the EWE Flood Development project, dry gas cap injection has been shut down in EWE and is being replaced by a water and miscible injectant flood. The objectives of this project are to reduce produced gas by injecting water to sweep out the expanded gas cap and gas underruns, provide additional oil recover through flood displacement, and access additional reserves through MI injection. Well Z-14A will be strictly a water injection well (no MI). It will provide the only water injection, in the area, into Ivishak zones 2 and 3. The well currently does not exhibit full mechanical integrity. The plan to prepare for injection and to show that Z-14^ is capable of accepting water injection is attached. If you have any questions concerning this Sundry Application, please don't hesitate to call me at 564-5196 or e-mail me at luedkeb @ bp.com. Sincerely, Beverly K. Luedke-Chan Greater Prudhoe Bay Production Engineer, W and Z Pads SCANNED DEC t ~ 2002 Well Z-14A Current Status: MITOA passed on 7/12/01. MITIA failed (on pressure stabilization) 7/12/01. PPPOT-IC passed on 7/13/01 after the Y seal was reenergized. All gas lift valves have been replace with dummy valves. Needs bond log and CT perfs. MITIA summary: Began pumping down IA Pressured up IA to 2500 psi with 16 bbls of diesel. IA lost 180 psi in 15 minutes. Bumped back up. IA lost 160 psi in 15 minutes. Pressured back up. IA lost 160 psi in 1St 15 minutes and 140 psi in 2nd 15 minutes for a total of 300 psi in 30 minutes. Pumped IA back up to 2500 psi with 1.25 bbls. Bled IA back to 500 psi. Conclusion: the MITIA failed on pressure stabilization. The leak is significantly less than 10 gpm, and would be very difficult to detect with current tools available. Plan Forward: 1. Set a mechanical plug in the tubing tail (TTP) 2. CMIT TxIA. Obtain State witness of CMIT and MITOA. If the MITOA and the combined tubing by inner annulus MIT passes, request a variance for water injection only (no MI). 3. Pull plug from tailpipe. 4. Obtain a cement bond log (SCMT) to show adequate cement coverage between the top Sag River and the next highest hydrocarbon zone (Kuparuk) 5. Add Perfs in Ivishak zones 3 and 4 with service coil. 6.

Well Z-14 is being evaluated for conversion to an injector. After failing an initial MITIA, a CMIT TxlA passed against an IBP. Listed below is a chronology of recent events. > 07/06/01: SL ran DGLV's. > 07/08/01: MIT-IA Failed, LLR 1.5 GPM. > 07/27/01: IBP set. > 07/30/01: CMIT TxlA Passed, lost 7/3 psi in 15/30 minutes. > 08/04/01: CMIT TxlA Passed, AOGCC witnessed. Tbg/IA lost 80/40, 10/60 at 15 and 30 minutes. > 08/05/01: Both tubing and IA pressure decreased from 2200 to 680 psi overnight. The passing CMIT TxlA on 8/4/01 demonstrates competent production casing. The failing MITIA on 7/8/01 indicates there is a slow tubing leak, 1.5 GPM. With your concurrence, our proposed plan is to puli the IBP, initiate water injection and submit a sundry request. Please let us know if you have any questions.

This well is a producer that BP plans to convert to injection. A plug had been set in the tubing tail due to a suspected leak between tubing and IA. Two attempts were made to pressure test the IA with the results of both tests indicating a slow leak from the IA to tubing. The tubing was then pressured up equal to the IA pressure and observed for 30-minutes. The results of this test were inconclusive (possible slow leak past plug) but the reduced bleed rate appears to bear out the earlier conclusion of a slow leak tubing by IA.

RIH to 11548' ctmd. Displace wellbore with 2%KCL water to fluid pack backside. Initial injectivity test: 0.3 bpm at 1940 psi. Pump 35 bbls 12% Hcl/10% Xylene acid (additives described below) and let soak at perforations. Inject into perforations, staying below frac pressure while reciprocating across perforations. Saw an immediate increase in injectivity to 0.6 bpm at 1000 psi. Injectivity at end of acid 0.8 bpm at 1500 psi. Over displace with 100 bbls 2% KCL water. Injectivity after displacement was 0.5 bpm at 1750 psi. It appears that very little benefit was gained from the stimulation. Pulled out of hole. Freeze protect coil with Meoh.
