Chris- WNS injector CD2-08 (PTD #202-250) was reported to have 2200 psi on the IA. The well has 7” 26 lb/ft L-80 which has an internal yield pressure of 7240 psi. The well was secured in 2014 due to two tubing leaks and has remained secured since. DHD will conduct a tubing and IA draw down test and depending on the results, additional diagnostics will be conducted to determine the cause of the IA pressure increase. At this point in time, CPAI does not intend to return the well to injection and any diagnostics conducted will be in order to ensure the well remains secured from the reservoir while shut in. Please let me know if you have any questions or disagree with the plan. Attached is a well bore schematic and 90 day TIO plot. Dusty Freeborn Well Integrity Specialist ConocoPhillips Alaska, Inc.

Some of these wells were found to have a void in the conductor by surface casing annulus. The voids that were greater than 3 feet were first filled with cement to a level of approx. 1.0 foot. The remaining volume of annular void respectively was coated with a corrosion inhibiter, RG2401 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 cement top-fill operation was completed on March 21st, 2007. Schlumberger Well Services mixed 15.7 ppg Arctic set I in a blender tub. The cement was pumped into the conductor bottom and cemented up via a hose run to the existing top of cement. The corrosion inhibitor sealant was pumped in a similar manner March 21 st - 22n , 2007. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each conductor. Please call Jerry Dethlefs or M.J. Loveland at 907-659-7043, if you have any questions. Sincerely, Œ7# ;::: Arend - ConocoPhillips Well Integrity Field Supervisor ~ ~~NED MAR 2 B 2007 Attaclunent . . ConocoPhillips Alaska Inc.

The Well will be conducted as a tract operation to test the Alpine C Sand (the "Tract Operation"). CPAI anticipates commencing the drilling of the Well in the first quarter of 2003. CPAI shall serve as Operator for the Well and Tract Operation. The Tract Operation represents a modification of the CD1-20 well the Parties previously proposed to drill pursuant to Attachment 5 to the Second Unit Plan of Development (POD), Colville River Unit dated September 15, 2002. CD1-20, a 2,500 ft. long horizontal well that was to be drilled from CD1 pad, is now being drilled from CD2 pad and has been renamed CD2-08. Below are the outdated POD coordinates, the current planned coordinates, and coordinates for a possible extension* (if the bit remains in sand) : The outdated POD coordinates are as follows: Surface Well Name CD1-20 Bottomhole Well Name 74 Well Service Injector Proposed Start of Completion X starVY start 377266/5981658 Proposed End of Completion X starVY start 376124/5983882 oqrt'\ f,~'/.

If successful, the Well will be completed as an injector'well to accommodate the MWAG flood process. Moreover, if the Well proves to be a "Qualified Injection Well", it will be treated in accordance with Article 9 of the CRUA and allocation in accordance with Article 10 of the CRUA. Please accept th.is letter as a request for approval for the Tract Operation. After the drilling of the Well" CPAI will inform ADNR and ASRC of our findings and outline ,our plans forward for the Well.

CD2-13 will be the closest well to C02-08. \l\Iell separation is 24.6 ft at 950 ft MD. Accounting for survey uncertaintYr the ellipse to ellipse separation is 7.3 it at 950 ft MD. Drilling Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. /" Lost circulation: Faulting within the Alpine reservoir section is considered the most likely cause of lost circulation. Standard LCM material has proved effective in dealing with lost circulation in previous development wells. 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. Annular Pumølng Oøerations: Incidental fluids developed from drilling operations on well CD2-08 will be injected into a permitted annulus on CD2 pad or the class 2 disposal well on CD1 pad. The CD2-08 surface/intermediate casing annulus will be flushed with 300 bbls of fresh water prior to freeze protecting with diesel to 2000' TVD. The only significant hydrocarbon zone is the Alpine reservoir and there will be 500' of cement fill above thêlõP»f the Alpine as per regulations. ,,'iI~.l We request that CD2-08 be"r,permitt,.ßG"'fôr annular pumping of fluids occurring as a result of drilling operations, per regulation 2õ7}iAG--2Þ;080. As stated above, any zones containing significant hydrocarbons will be isolated prior to initiãt1ng-'ãnnular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Reference the enclosed directional drilling plan for other formation markers in this well. Surface casing will be set near the below the base of the Schrader Bluff Formation (C-40). These 300- J' 400' thick shales are part of the Colville Group and are known to provide vertical barriers to fluid flow in other areas. The maximum volume of fluids to be pumped down the annulus of this well will not exceed 35,000 bbl ./ without the specific permission of the AOGCC. Fluid densities will range from diesel to a maximum of 12.0 ppg for drilling fluid wastes. Using 12.0 ppg fluid and the rig's specified maximum pumping pressure of 1,500 psi for annular injection, the maximum pressure at the surface casing shoe is estimated by: Max Shoe Pressure = (12.0 ppg) * (0.052) * (Surf. Shoe TVD) + 1,500 psi = (12.0 ppg) * (0.052) * (2390') + 1,500 psi = 2,990 psi Pore Pressure = 1,081 psi Therefore Differential = 2991 - 1081 = 1910 psi. / The internal casing pressure is conservative, since frictional losses while pumping have not been taken into consideration. The surface and intermediate casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the following table: Wt Connection 850/0 of 85% of OD (ppf) Grade Range Type Collapse Collapse Burst Burst 9-5/8" 36 J-55 3 BTC 2,020 psi 1,717 psi 3,520 psi 2.992 øsl ./ 7" 26 L-80 3 BTC-Mod 5,410 psi 4.599 øsi 7,240 psi 6,154 psi vi J ¡""C''> "~ /'~e ~ 1 A Î1ll1 i i:~/l~ ~ C02-OS DRilLING FLUID PROGRAM Density PV YP Funnel Viscosity I nitial Gels 10 minute gels API Filtrate H PHT Fluid Loss at 160 PH KCL Surface Hole: ) SPUD to Intermediate hole to 7" Production Hole 9-5/8"surface casing casing point - 8 %" Section - 6 1/8" point -12~" I 9.6 - 9.8 ppg /' 9.0-9.3 ppg / 8.8 - 9.6 ppg 10 - 25 10-15 20 - 60 15 - 25 25 - 30 100 - 200 4-8 10-15 <18 12 - 20 NC - 10 cc 130 min 4 - 12 cc/30 min (drilling) 12 - 14 cc/30 min 8.5-9.0 9.0 -10.0 9.0- 9.5 60/0 A standard high viscosity fresh water 1 gel spud mud is recommended for the surface interval. Keep flowline 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 1 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 Alpine 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 production interval will be drilled with aM-I Flo-Pro drill-in fluid. The base fluid will consist of 6% KCI, with ± 30PPB 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. J n ~ ,~ ~ ,~' G ~ L EW'/;1 .; ,':;:, " .:' 'I, : , I M ~~ § j\ti ~",~, ..

Test BOP's to 5000 psi. PROCEDURE FOR CALCULATING ANTICPATED SURFACE PRESSURE (ASP) ASP is determined as the lesser of 1) surface pressure at breakdown of the formation casing seat with a gas gradient to the surface, or 2) formation pore pressure at the next casing point less a gas gradient to the surface as follows: 1) ASP = [(FG x 0.052) - 0.1]0 Where: ASP = Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in Ib/gal 0.052 = Conversion from Ib.lgal to psi/ft 0.1 = Gas gradient in psi/ft 0= true Vertical depth of casing seat in ft RKB OR 2) ASP = FPP - (0.1 x D) Where; FPP = Formation Pore Pressure at the next casing point ASP CALCULATIONS 1. Drilling below conductor casing (16") ASP = [(FG x 0.052) - 0.1] 0 = [(10.9 x 0.052) - 0.1] x 114 = 53 psi OR ASP = FPP - (0.1 x D) / = 1081 - (0.1 x 2390') = 842 psi 2. Drilling below surface casing (95/8") ASP = [(FG x 0.052) - 0.1] 0 = [(14.5 x 0.052) - 0.1] x 2390 = 1563 psi OR ASP = FPP - (0.1 x D) / = 3204 - (0.1 x 7079') = 2495 psi 3.

V-' . ~elll( \ ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an on~ore e.w~n well from the Alpine CD2 drilling pad. The intended spud date for this well is January 8, 2002. It is intended that Doyon Rig 19 be used to drill the well. CD2-08 will be drilled to penetrate the Alpine reservoir horizontally. After settin~ intermediate casing, the horizontal section will be drilled and the well completed as an open hole injector. At the end of the work program, the well will be closed in awaiting completion of well wor~...9nd- ilities work that will allow the well to begin -- production ./" .1'..-'" Note that it is planned to drill the surface hole ¡thout a diver. There have been 38 wells drilled on CD1 pad and 27 surface holes drilled on CD2 pad with no si nificant...¡ aication of gas or shallow gas hydrates. All of the wells on CD2 have surface casing shoes within a 20 adius of the planned surface casing shoe of CD2-08. ...-- The intermediate hole section on CD2-08 is +/- 9375 ft long. It is planned to drill the section in one run, which could take more than 8 days. ConocoPhillips is requesting that the weekly BOP test requirement be extended to two weeks. This will ensure that the hole section can be drilled and 7" casing ran without having to trip the drilling assembly for the BOP test. It is also requested that the packer placement requirement be relaxed to place the completion packer 300ft TVD /' above the Alpine formation. This will place the completion at a maximum inclination less than 650 and allow access to the completion with standard wireline tools for future intervention. 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: -Form 10-401 APPLICATION FOR Permit to Drill per 20 ACC 25.005 (a). -Fee of $100 payable to the State of Alaska per 20 ACC 25.005 (c) (1). -A proposed drilling program, including a request for approval of annular pumping operations. -A drilling fluids program summary. -Proposed completion diagram. -Pressure information as required by 20 ACC 25.035 (d)(2). -CD2-08 Cementing Requirements. -Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b). Information pertinent to this application that is presently on file at the AOGCC: -Diagrams of the BOP equipment, diverter equipment and choke manifold layout as required by 20 ACC 25.035 (a) and (b). -A description of the drilling fluids handling system.
