Those wells that are not re -drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task --Respoimible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box Geologist in the upper left corner of Form 10-403 is checked. If the "Abandon" or E "Suspend" boxes are also checked, cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon" box is checked in Box 15 (Well Status after proposed Geologist work) the initial reviewer will cross out that erroneous entry and initial the it on both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, check the "Suspended" box and initial that change. Drilling Engineer The drilling engin6ers will serve as quality control for steps I and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the "Plug Stat Tech for Redrill" box, they will enter the Typ_Work code "IPBRD" into the ' History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, they will check the Stat Tech History tab in RBDMS for the "Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re -drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, they will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will Stat Tech change the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Stat Tech Geologists will check the "Well by Type Work Outstanding" user query Geologist in RBDMS to ensure that 0 of the Plug for Redrill wells have been handled properly. At this same time, they will also review the list of suspended wells for accuracy. 1,000,000 L C 100,000 1z 10 Jan -1990 BP Exploration (Alaska) Inc., PRUDHOE BAY UNIT F-48 (191-086) PRUDHOE BAY, PRUDHOE OIL Monthly Production Rates Jan -1995 - !an -2000 Jan -2005 Jan -2010 Jan -2015 e Produced Gas (MCFM) .

To: Tom Maunder, Petroleum Engineer Alaska Oil & Gas Conservation Commission From: John Rose, ODE Date: May 21,2007 Re: PBU F-48 RWO (Application for Sundry Approval) Scope of Work: This primary focus of this workover is to eliminate the 1A x OA communication problem that currently exists with this well. The planned ''fix'' for this IA x OA communication problem will include one or all of the following RWO activities/procedures: 1. Change-out the IC packoff. 2. The possible replacement of any bad 9-5/8" production casing that can be cut and pulled and re-run to surface. 3. A 7" "scab" liner which may be used to cover/isolate any bad 9-5/8" production casing which is covered with cement and cannot be cut and pulled. After pulling the current 4-1/2" completion, specific leak detection work will be performed on the well which will then dictate the path-forward well work that will be required. Please note the following outline as provided below for more specific details regarding the workover plans for this well. MASP: 2275 psi Well Type: Ivishak Producer Estimated Start Date: August 12, 2007 F-48 RWO Planned Operations Summary (05/18/07) Pre-Ria 01 erations: (Work needs to be done within a 45 days 2ES movina onto well.) 1. S Pull PX plug from X-nipple at 12,158' MD. 2. S Drift well to confirm the current PBTD w/3.833" drift (locate WLEG on drift run). 3. E Set HES FasDrill at -12,203' MD and pressure test to 3500 psi (set in the only full joint of 4-1/2" tubing below the current 4-1/2" HBBP permanent packer at 12,158' MD).

E Chem cut the 4-1/2" tubing (to insure a "clean" stub looking up) at -12,162' MD (2' into the 10' pup just below the X-nipple profile at 12,158' MD). 5. P Fluid pack well with seawater through the tubing cut at 12,162' MD. 6. E Run 4-1/2" tubing caliper to confirm the condition of the tubing string. 7. E CMIT TxlA to 3500 psi. If test fails, run LDL to confirm "leak" (the leak may be associated with the condition of the IC pack-off). 8. P MIT the OA to 2000 psi. 9.

MU an 8-1/2" clean-out assembly to include a 9-5/8" casing scraper and clean-out the well to top of the tubing stub at 12,162' MD. 8. RU E-line. Make CCUGR/JB and USIT logging runs from tubing stub to surface looking for 9-5/8" casing leaks and to confirm the TOC on the back-side of the casing. (NOTE: TOC on 9-5/8" casing estimated to be just below surface casing shoe at 2755' MD and there is no record of any cement job in the 13-3/8" x 9-5/8" annulus as 161 bbls of crude (total OA annular volume) was pumped into that annulus at wells end.) 9. If it is concluded that the IC pack-off is the only source of the OA x IA communication in this well and that the over-all condition of the existing 9-5/8" casing is considered to be "good", change-out the IC pack-off and proceed to Step #12 of this wellplan to run a stacker-packer completion. 10. If a "leak" or bad 9-5/8" casing is determined to be above the TOC in the 13-3/8" x 9-5/8" annulus, cut and pull the existing 9-5/8" casing from above the TOC and run and fully cement a new tie-back 9-5/8" casing string. With the new 9-5/8" tie-back casing successfully cemented in place, proceed to Step #12 of this wellplan to run a stacker-packer completion. 11. If a "leak" or bad 9-5/8" casing is determined to be below the TOC on the back-side of the 9-5/8" casing, continue the de-completion phase of this RWO by removing the rest of the 4-1/2" completion in the well (this includes the removal of the HBBP packer at 12,170' and tailpipe assembly). With the well de-completion complete, run a 7" "scab" liner from the top of the existing 7" liner tie-back at 12,195' MD to some point up the well to effectively cover the bad 9-5/8" casing (-3000' MD). With the scab liner successfully cemented in place, proceed to Step #13 of this wellplan to run a new 4-1/2" single production packer completion. 12. MU a clean-out BHA and RIH and drill-out the FasDrill plug in the 4-1/2" tubing tail at 12,203' prior to running a new 4-1/2",12.6#,13 Cr80, VamTop stacker-packer completion. 13. Run 4-%",12.6#, 13Cr-80, VamTop conventional single production packer completion. 14. Displace the IA to packer fluid and set the packer. 15. Test tubing and IA to 3500 psi.

Supervisor DATE' December 7, 2000 FROM. Jeff Jones, Petroleum InspeCtor SUBJECT: Safety Valve Tests Prudhoe Bay Unit BPX / F-Pad ThUrsday, December 7, 2000: I traveled to BPX's F-Pad in the Prudhoe Bay Field to witness Safety Valve System tests. Merv Liddelow, BPX representative in charge of testing, performed the tests in a safe and proficient manner. Of the 28 wells tested, 10 failures were witnessed. For the most part, frozen contaminants (water) in the block valves upstream of the pilots and in the SSV hydraulic control lines caused the failures. On 12/8/00 Mr. Liddelow indicated to me that aii SVS failures had been corrected and J J_ successfully re-tested. The 17.8% SVS failure rate requires a 90-day test cycle for this pad. The AOGCC test report is attached for reference. I conducted 28 well house inspections concurrent with the SVS tests. Due to recent high winds, several well houses were drifted with snow inside. In addition, SVS hydraulic fluid leaks Were noted on wells F-12 and F-13A. Mr. Liddelow indicated that these items would be addressed. No other exceptions were noted.

Pumped hole volumn, but were unable to fluid pack well. Continue in hole and dropped thru jewerly and tubing tail. Pull up thru tubing tail and nipples. Had good "locates". Try to drop back thru "SWS" nipple, but unable to get thru. Try with pump rate. Still unable to get down hole. Quit trying. Pull out of hole. Close swab. Lay down tools and packer. Packer ok, tools ok. Cap BOPs and secure well for night. Do something different in AM.Resume operations. Pick up BHA//2. Start in hole while pumping sea water to flush tubing. Drop thru jewedy and tubing tail. Set TAM Single Set packer with center of element at 12,620" CTD. Rig up BJ. Hold safety meeting and pressure test lines. BJ pump 100 bbls of 5% HCL and acidize the perforations from 12,653' to 12,678'. Displace coil and over-flush acid into perfs with 200 bbls filtered sea water. Rig down BJ. Release packer and pull up to tubing tail. Park to relax element. Enter tubing tail and eased thru jewerly. Continue pulling out of hole. Finished out of hole. Closed swab valve and remove fusible cap. Lay down packer and tools. Rig down CTU. Leave well shut in. Turn well over to MOC, Pad Operator, and Trico for flowback. TAM SS packer worked perfect again. Had no trouble getting into tubing tail and thru nipples. Lost rubber (approx 90%) element around 5000' as indicated on weight indicator. All bands recovered. No evidence of communication above packer during job. FLUIDS PUMPED BBLS 562 100 200 Sea Water (filtered) 5%HCL (chrome inhibs added. Also Fe 300 and Fe210). Sea Water Displace/Over-flush.
