As noted in my message below, you can reference the temp survey and well schematic already submitted. Please provide a TIO pressures plot inclusive of the temp survey timing. AIO 3, Rule 7 (amended October 27, 1986) requires approval to cantinas injecting in GC-2E. The approval called for in Rule 7 is handled through the administrative approval process that has been used as the standard process for injector integrity concerns. AIO 3, Rule 9 references administratively amending rules. While you suggest that there are no rules in AIO 3 to amend, I believe we need to separate current practice from the requirements of AIO 3: - Rule 4 establishes a weekly monitoring schedule for wellhead pressures; GC-2E is currently monitored daily as I understand BPXA well integrity policies; amending this rule to be in line with BPXA monitoring frequency would be appropriate far GC-2E; - Rule 6 establishes a 4 year MIT requirement using pressure testing; since the integrity loss is below the packer, it may be more appropriate to amend the admin approval for GC-2E to require a temp survey every 2 years in lieu of or in conjunction with the pressure test of the IA (above the packer); also, I understand BPXA's policy is to perform the MITIA every 2 years, so alignment with this requirement under an admin approval would constitute an amendment. Jim Regg AoGCc 333 W.7th Avenue, Suite 100 Anchorage, RK 99501 phone: 907-793-1236 fax: 907-276-7542 ~~8~ MAY ~ ~ 2008 From: Engel, Harry R [mailto:Harry.Engel@bp.com] Sent: Wednesday, April 30, 2008 2:30 PM To: Regg, James B (DOA) Cc: NSU, ADW Well Integrity Engineer; Engel, Harry R; Bill, Michael L (Natchiq); Maunder, Thomas E (DOA) Subject: GC-2E (PTD #1970180) Potential 7" Casing Leak Jim- After reviewing Area Injection Order 3 (A10 3) further I believe an Administrative Approval is not necessary for continued operation of GC-2E. A10 3, Rule 7, (amended October 27, 1986) states: "Whenever operating pressure observations or pressure tests indicate pressure communication or leakage of any casing, tubing or packer, the operator must notify the Commission on the first working day following the observation, obtain Commission approval of a plan for corrective action, and when an USDW is not endangered, obtain Commission approval to continue operation." During routine well surveillance in February 2008 a potential 7" casing leak was observed at approximately 4320' MD, approximately 190' above the perforated interval and within the permitted injection interval of 3115' MD to 5912' MD. The temperature survey was initiated to evaluate the well 5/1/2008 GC-2E (PTD #1970180) Potential 7" Casing Leak Page 2 of 3 for possible solids injection a confirm that the injected fluids w~onfined to the approved injection interval. The results i icate injection fluids are confined to the permitted interval. Operating pressure observations or pressure tests did not indicate any pressure communication. The well is currently on a two year MIT schedule. The well passed an AOGCC witnessed MIT to 2300 psi in August 2006. The location of the potential 7" casing leak at approximately 4320' MD does not impact the mechanical integrity of the well or influence fluid movement into underground sources of drinking water. The well conforms to BP policy and complies with AOGCC regulations. Additional corrective actions at this time are not necessary for the continuation of safe operations. AIO 3, Rule 9, states: "Upon request, the Commission may administratively amend any rule stated above as long as the operator demonstrates to the Commission's satisfaction that sound engineering practices are maintained and the amendment will not result in an increased risk of fluid movement into an underground source of drinking water." I believe the well's condition does not warrant a request to "administratively amend" any rule in A10 3. Considering the information above, I believe an Administrative Approval would impose unnecessary administrative burden upon the AOGCC and BPXA. I propose we continue operation of the well with a 2 year MIT schedule. The well is currently shut in yet it is available for use if required. We will continue to monitor operating conditions and will keep the Commission informed of any significant changes to the mechanical condition of the well. Enclosed is the well bore schematic and current TIO plot. I look forward to your response.

Page 3 of 3 • Jim, As requested from our phone conversation, I have sent this email to summarize the potential 7" casing leak in GC-2E (PTD #1970180). After review, please advise if an Administrative Approval is necessary for continued injection. A temperature log was run on 02/18/08 with four passes. The baseline pass indicates a sizable temperature increase at 4,320' MD (or 4,168' TVD). 1000 bbls of 105 degree KCI water was then pumped and logging run WB1 was done (see attached plot). WB2 and WB3 occurred at 2 hour intervals there after. All of the logging runs indicate an increased temperature at the same depth of the baseline pass. «GC-2E Temp Log 021808.x1s» «GC-2E.pdf» This information indicates a potential casing leak approximately 190 feet above the perforated interval. Although we are permitted to inject up to the SV3 marker at 3,000 TVD, is an AA required for continued injection? Please call with any questions or concerns.

O/~ I spoke with AG's office about this; based on the better characterization of the solids content you provided, we believe the proper approach is an administrative approval request under AID 3 to add the small amount of solids into the disposal stream at PBU GC-2 wells. There are a couple issues that should be provided with your request: 1) reason for the request 2) frac modeling results you have run that verifies acceptable confinement; 3) commitment by BP for testing and monitoring the mechanical integrity of the well; this well is a monobore injector with a significant interval between the packer and injection zone, so any testing must address the injection tubular below the packer; 4) caliper survey of the well for a baseline before adding the solids stream. Give me a call if you have any questions. Jim Regg AOGCC Bill, Michael L (Natchiq) wrote: Jim, We are stHI interested in pursuing this project and I am remiss at following up with you.

Subject: RE: FW: GC-2 Disposal Wells Jim, We have looked in more detail at the proposed GC-2 disposal of produced solids from sand jetting processing vessels, and believe the amount of solids may be somewhat lower than represented to you earlier. Below is a summary of the current view of the project: Operations would consist of batch injection of about 240 bbls of 12 ppg density slurry every 2 weeks at the most. This concentrated slurry would be mixed with 3450 barrels of produced water and the dilute slurry (about 7% by volume) injected over the course of about 4.5 hours. On the average, the solids content during a 2 week cycle would be low, about 0.14 % by volume. This is a much lower concentration than the G&I project where each cycle involves continuous disposal of about 9.5 ppg slurry (+/- 12 % solids). We believe the disposal of these solids wíll cause little or no change to the stress within the formation or the injection character of the GC-2 disposal wells. No grinding is required during this process and the maximum particle size is much lower than at G&I (14 mesh at G&I versus 90% is smaller than 80 mesh and 50% is smaller than 200 mesh at the GC-2 slug catcher). Based on this information, please confirm if this disposal operation will require a modification to Area Injection Order #3 or if it may be considered under the Administrative Relief provision of the order contained in Rule 9. We believe this project meets the "sound engineering practices" requirement of that rule. Aquifers in this this area are exempted for Class II injection activities under Aquifer Exemption Order No.1. We are pursuing frac modeling of this process to verify acceptable confinement of the waste and wi!! provide that information to you as it is available, I will be out of the office from 5/16 through 5/30. Should you have any questions, please call Richard Clausen at 564-4085 or Don Andrews at 345-3074.

Slurry injection was not contemplated in AIO 3, therefore, the proper way to handle this conversion is to amended AIO 3. We would expect more geological information on confining layers and receiving zone, fÌacture modeling, expected injection performance (rates, pressures), and monitoring/surveillance/testing that will be instituted, particularly since these wells are monobores. You would not need to restate 20f5 10/3 I/2006 I I :05 AM Ke: tW: tW: GC-2 Disposal Wells . . . information, findings, conclusions that are already the basis for AIO 3. Some baseline integrity information would also be necessary (caliper, temp survey, etc.) given these wells are effectively monobore completions (single string of pipe between conveyed fluid and formation over extended section of well bore) and would not normally qualify for slurry injection. The lack ofUSDWs provides some latitude for less stringent well construction and could be the basis for approving your request. The Commission has been working on revisions to all injection orders to standardize well integrity language (Rules 4,5,6, 7 in AIO 3). This will be a good opportunity to address your request and accomplish our efforts in a single amendment.

The facility modifications and the use of the wells for periodic slurry disposal are necessary to support the Prudhoe Schrader Bluff developments. Enclosed are the well bore schematics for the active disposal wells at GC-2. GC-2C has been shut in since early 2005, but the max injection pressure since 2004 was about 2000 psi. It had a wide variation of daily injection rates, with a few days of up to 60 mbpd during the period 2004 to early 2005. GC-2E is currently active. The max injection pressure since 1/1/05 was about 1850 psi. Again there was a wide variation in injection rates, but there were a few days up to 80 mbwpd during that period. In February '06, GC-2E injection averaged about 12 mbwpd. For permit purposes, we prefer to maintain the maximum disposal well injection pressure cíted in the Area Injection Order #3 application at 2300 psi. We expect the injection rate will normally be less than 25 mbpd, although there will be higher rates during upset conditions. During solids disposal, the slurry density will range between 9 and 10 ppg, depending on the amount of dilution. The last entry in GC-2C was a fill cfeanout in 07/04.

As the attached AOGCC BOPE test report shows the test lasted 3 hours with 1 failure. The kill line HCR failed to pressure test and was replaced with a manual valve that tested good. The rig was clean and all related equipment appeared to be in good working order. The location though extremely crowded was well organized allowing good access to the rig.

GC-2E Cretaceous Injection Well ~3perational Summary 1. MIRU. NU diverter and function test same. 2. Drill 12-1/4" hole to _+ 3,672' MD, (3,500' TVDs$). Run and cement 9-5/8", 40#, L-80 casing to surface. 3. Install blowout prevention equipment consisting of 5,000 psi W.P. pipe rams, blind rams, and annular preventer. Function test BOPE to 5,000 / 250 psi. 4. Test 9-5/8" casing to 3,500 psi for 30 minutes. A formation leak-off test will be performed 20' below the surface casing shoe. 5. Directionally drill 8-1/2" into the Cretaceous to a TD of ___5,994' MD (5,667' TVD). Note: Inclination, azimuth and total depth may be adjusted by the onsite geologist. Run electric line logs (resistivity and porosity) and RFT over the prospective injection intervals to confirm pressure predictions and identify the lowest pressure interval to perforate. Run 7", 26#, L-80 liner (minimum 150' overlap inside 9-5/8" surface casing shoe) and cement in place. TOC planned for top of liner. Test casing to 4,000 psi for 30 minutes. Note: Perforating work to be performed after rig release. RU and run 7", L-80, production tubing and sting into the top of the 7" liner (with seal assembly). Set production packer. Test tubing to 4,000 psi for 30 minutes. Test annulus to 3,500 psi for 30 minutes. Set two way check and test to 1,000 psi. ND BOPE. NU tree and test to 5,000 psi. Freeze protect well and release rig. , , , , 10. 11. Drilling Hazards Pore pressure may be as high as 10.2 ppg EMW in the Cretaceous due to nearby produced water injection. No potential hydrocarbon-bearing zones expected. Lost circulation is possible in the Cretaceous sands. GC-2 is not a producing pad, however significant produced water injection occurs with water from known H2S producing wells. Appropriate H2S precautions are to be observed at all times while the drilling rig is on location. These precautions include, but are not limited to: · Proper training of all onsite personnel, unescorted visitors and temporary onsite personnel; · Monitors with both audible and visual alarms; · Access to 5-minute emergency escape air packs; · Personal H2S monitors; · Working wind indicator; · Posted evacuation routes (minimum of two); · Muster points in designated safe areas; · Frequent H2S drills; 16:34 SPERRY-SUN PAGE 82 IShared.Services Drilling Structure".
