BOX 100360 ANCHORAGE, ALASKA 99510 -0360 April 01, 2011 a0-7- 1)g Commissioner Dan Seamount Alaska Oil & Gas Commission 333 West 7 Avenue, Suite 100 Anchorage, AK 99501 *MAU APR O 7 Z01 Commissioner Dan Seamount: Enclosed please find a spreadsheet with a list of wells from the Alpine field (CRU). Each of these wells was found to have a void in the conductor. These voids were filled with cement and corrosion inhibitor, engineered to prevent water from entering the annular space. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10 -404, Report of Sundry Operations. The corrosion inhibitor /sealant was pumped March 13 -15 and March 27 -28, 2011. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each conductor. Please call MJ Loveland or Perry Klein at 907 - 659 -7043, if you have any questions. Sincerely, MJ Loveland ConocoPhillips Well Integrity Projects Supervisor • • ConocoPhillips Alaska Inc.

Each of these wells was found to have a void in the conductor. These voids were filled with cement if needed and corrosion inhibitor, engineered to prevent water from entering the annular space. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations. The corrosion inhibitor/sealant was pumped March 18~', 2009. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each conductor.

A coil cleanout will only be performed should it be necessary post-frac. Procedure: 1. MIRU at least ten clean insulated frac tanks. Load tanks with Seawater from CD2 injection manifold. (approximately 4500 bbls are required for the treatment) 2. Rig up Schlumberger pumping services equipment and stab the Tree Saver. (Test tree saver seals to expected pressure using warm diesel to assure seal integrity in tubing hanger) 3. Pressure test surface lines to 9000 psi 4. Pump the 300 bbl Breakdown with YF125ST fluid with L-65 Scale inhibitor (50 gpt). Bring pumps up to maximum rate ASAP. SD and obtain ISIP & Pc. a. Pump Schlumberger's schedule at 20-25 BPM with a maximum pressure of 8000 psi, add breaker as per lab results. Maintain 3500 psi on the IA during the treatment using Little Red's pump truck. b. 4 Stages of 2,4,7 PPA ramped containing: • 1260 bbls dirty YF125ST dropping to 1220 bbls for the remaining three stages (3660 bbls) • :611 Mlbs. -16/30 white sand • 66 bio-balls via the ball drop after each 7 ppa stage (200 balls total) • Flush with 90 bbls YF125ST; 90 bbls WF125, and 44 bbls diesel (224 bbls tubing volume to mid liner depth) i TUBING - (120-17152, OD:3.500, ID:2.992) 'RODUCTION --- (0-17716, OD:7.625, W t:29.70) PACKER ;16601-16602, OD:6.620) NIP -- ;16679-16680, OD 3.960) SUB ;17128-17129, OD:6.410) SLEEVE -- ;17131-17132, OD:7.630 ) HANGER ;17144-17145, OD:7.000) XO Bushing -- ;17157-17158, OD:5.500) Perf ;17826-24988) LINER ;17131-25030, OD:4.500, W (:12.60) Can~~c~PhllP~ l41~~k~F Irn~.

Omission Anohargaq ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an onshore producer well from the Nanuq CD4 drilling pad. The intended spud date for this well is 09/08/07. It is intended that Doyon Rig 19 be used to drill the well. i CD4-07 will be drilled to penetrate the Alpine reservoir horizontally. After setting 7-5/8" intermediate casing, the horizontal section will be drilled and the well completed as pre- perforated liner producer. At the end of the rig work program, the well will be flowed back to ~ mitigate reservoir damage. The well will then be closed in awaiting completion of well work that will allow the well to begin production fourth quarter 2007. It is requested that a waiver of the diverter requirement under 20 AAC 25.035 (h)(2) be granted. There have been 15 surface holes drilled at CD4 and there has not been a significant show of ~ shallow gas or gas hydrates. Please find attached the information required by 20 ACC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1. Form 10-401 APPLICATION FOR Permit to Drill per 20 ACC 25.005 (a). 2. Fee of $100 payable to the State of Alaska per 20 ACC 25.005 (c) (1). 3. A proposed drilling program 4. A drilling fluids program summary. 5. Pressure information as required by 20 ACC 25.035 (d)(2). 6. Directional drilling /collision avoidance information as required by 20 ACC 25.050 (b). Information pertinent to the application that is presently on file at the AOGCC: 1. Diagrams of the BOP equipment, diverter equipment and choke manifold lay out as required by 20 ACC 25.035 (a) and (b). 2. A description of the drilling fluids handling system. 3.

ORIGINAL • • Well Proximity Risks: Directional drilling /collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD4-208 is the closest well. Well separation is 19' @ 625' MD. Drilling Area Risks: i It is possible that pressures higher than modeled could be seen. To mitigate this event, weighting material will be available to increase the. mud weight. Lost circulation: Faulting within the Alpine reservoir section is considered to be the most likely cause of lost circulation. Standard LCM material is expected to be effective in dealing with lost circulation. Additional care and attention will be given to the higher potential of inducing a kick when drilling horizontally as opposed to vertically. Good drilling practices will be stressed to minimize the potential of taking swabbed kicks.

Keep flow line viscosity at ± 200 sec/qt while drilling and running casing. Reduce viscosity prior to cementing. Maintain mud weight < 9.6 ppg by use of solids control system and dilution where necessary. Intermediate Hole Section: Fresh water gel /polymer mud system. Ensure good hole cleaning by pumping regular sweeps and maximizing fluid annular velocity. There is potential for lost circulation, particularly after the Nechelik is penetrated. Maintain mud weight at or below 9.8 ppg and be prepared to add loss circulation material. Good filter cake quality, hole cleaning and maintenance of low drill solids (by diluting as required) will all be important in maintaining wellbore stability. Production Hole Section The horizontal interval will be drilled with a M-I Flo-Pro drill-in fluid. The base fluid will consist of 6% KCI, with ± 30PP6 calcium carbonate bridging material to minimize formation damage. Flo-Vis Polymer and Dual-Flo starch will be used for viscosity and fluid loss control respectively.
