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 tOf 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 MJ. Loveland at 907-659-7043, if you have any questions. Sincerely, \27# ¡::: Arend- ConocoPhillips Well Integrity Field Supervisor -~ tiGANNED MAR 2. 8 2007 Attachment . . ConocoPhillips Alaska Inc.

ORIG'NAl Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD2-06 will be the closest well to C02-OS. Well separation is 7.9 @ 300' MD. Accounting for survey uncertainties, the ellipse-to-ellipse separation is 2.3' @ 300' 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 to be 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 Pumpina Operations: Incidental fluids developed from drilling operations on well CD2-0S will be injected into a permitted annulus on C02 pad or the class 2 disposal well on CD1 pad. The CD2-0S 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 the top of the Alpine as per regulations. Upon completion of CD2-05 form 10-403, Application for Sundry Operations, will be filed. Annular pumping of fluids occurring due to drilling operations, per regulation 20 AAC 25.080, could then begin once properly permitted. As stated above, any zones containing significant hydrocarbons will be isolated prior to initiating annular 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 base of the Schrader Bluff Formation (C-40). These 450-500' 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 TV D) + 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 8S% 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 psi 7" 26 L-BO 3 BTC-Mod 5,410 psi 4,599 psi 7,240 psi 6,154 ps i fiù IfQt -J ~ - : .'. ,,-<, .'~.. .. .~ ...·1 ,ifA~ ~,A L< '- C02-OS DRilliNG FLUID PROGRAM Density PV YP Funnel Viscosity Initial Gels 10 minute gels API Filtrate HPHT Fluid Loss at 160 PH KCL Oil Iwater ratio SPUD to 9-5/8"surface casing point - 12 %" 8.8 - 9.6 ppg 20 - 60 100 - 200 Intermediate hole to 7" casing point - 8 Y2" Production Hole Section - 6 1/8" 9.6 - 9.8 ppg 1 0 - 25 15 - 25 8.1-8.8 ppg ./ 10-15 25-30 NC - 10 cc 1 30 min 4-8 <18 4 - 12 cc/30 min (drilling) 1 0-1 5 12-20 NA 12-14 cc/30 min 9.0-9.5 6% Approx. 80/20 8.5-9.0 9.0 - 10.0 Surface Hole: A standard high viscosity fresh water / 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 ppgby 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 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 a 80/20 oil/water ratio M-I Versa-Pro mineral oil based drill-in fluid. The base fluid will consist of high flash point (>200 F) mineral oil with 25% by weight calcium chloride as the internal phase. Calcium carbonate bridging material will be added to minimize formation damage.

This equates to 7.6 ppg fluid and with 200 psi overbalance takes us up to the 8.1 ppg range of the intended drilling. In the unlikely event that abnormal reservoir pressure be encountered (above the .4525 psi/ft [3342 psi at max TVD] used in pore pressure calculations), the rig team will be poised to elevate the mud weights accordingly. Should you have any other questions or concerns feel free to contact me at the numbers listed below, or Vern Johnson at 265-6120.

Conoc~illipS June 1, 2004 Alaska Oil and Gas Conservation Commission 333 West 7'h Avenue, Suite 100 Anchorage, Alaska 99501 Re: Application for Permit to Drill CD2-05 Dear Sir or Madam: ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an onshore production well from the Alpine CD2 drilling pad. The intended spud date for this well is July 23, 2004. It is intended that Doyon Rig 19 drill the well. The well CD2-05 will then be drilled and landed in the Alpine sand horizontally. 7" casing will then be run and cemented in place. The horizontal section will be drilted with oil based mud using mineral oil as the base fluid. CD2-05 will be completed as producer with a perforated liner. At the end of the work program the well will be shut in awaiting surface connection. Note that it is planned to drill the surface hole without a diverter. There have been 41 wells drilled on CD1 pad and 47 wells drilled on CD2 pad with no significant indication of gas or shallow 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 1 0-401 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.
