Chris- CRU CD1-20 (PTD #204-240) was reported with an IA and OA pressure convergence. The well was previously secured from formation with a tubing plug due to a surface casing leak at 4’ 5”. DHD was deployed to investigate and found the WHPs at 342/326/318 psi with no current flow from the known surface casing leak. CPAI intends to bleed the well head pressures and conduct an initial set of diagnostics to attempt to identify the failure mechanism. Depending on the results of the diagnostics, CPAI will submit the proper notifications for a long-term plan or repair. Attached is a current 90- day TIO plot and well bore schematic. Please let me know if you have any questions or disagree with the plan. Dusty Freeborn Well Integrity Engineer ConocoPhillips Alaska, Inc.

I concur with your conclusion that the Alpine interval in this well is satisfactorily isolated. You have approval to begin injection into the well. Please make arrangements for an Inspector to witness an MIT once the well has thermally stabilized. The Inspectors may be contacted at 907-659-2714 or pages at 907-659-3607. Please call or message with any questions. Tom Maunder, PE AOGCC Hanson, Kelli L wrote: Mr. Maunder, CPAI requests approval to commence injection into CDl-20. The CDl-20 SCMT log is attached. The log indicates very good to excellent quality cement is present across the logged interval from 10,542' MD (6,944' TVD SS) up to the tubing tail at 10,114' MD (6,820' TVD SS). The packer is located at 10,040' MD (6,786' TVD SS) @ 61 deg. The top of the Alpine C sand is located at 10,520' MD (6,941' TVD SS) @ 81 deg.

Pressure test 4 1/2" X 7" annulus to 3550 psi, bled to 3475 psi in 30 minutes. Based on this information I've concluded the Alpine interval is adequately isolated in CDl-20. We would like to place this well on injection as soon as possible. Your early attention to this request would be appreciated.

NOTE: The Doyon 19 5000 psi BOP equipment is adeq~te. Test BOP's to minimum 3500 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 Iblgal 0.052 = Conversion from Ib./gal to psilft 0.1 = Gas gradient in psi/ft D = 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) = 1073 - (0.1 x 2372) = 836 psi 2. Drilling below surface casing (9 5/8") ASP = [(FG x 0.052) - 0.1] 0 = [(14.5 x 0.052) - 0.1] x 2368 = 1549 psi OR AS P = F P P - (0.1 x D) = 3174 - (0.1 x 7015') = 2473 psi 3. Drilling below intermediate casing (7") ASP = FPP - (0.1 x D) = 3213 - (0.1 x 7100') = 2503 psi o~' Colville River Field CD1-20 Injection Well Completion Plan 16" Conductor to 114' Updated 11/24/04 Sperry Sun Directional Plan WP 02 4-1/2" Cameo DB Nipple (3.812') at 1829' TVD = 2100' MD 9-5/8" 36 ppf J-55 BTC Surface Casing @ 2959' MD 1 2372' TVD cemented to surface Packer Fluid mix: 9 2 ppg KCI Brine with 2000' TVD diesel cap 4-1/2" 12.6 ppf L-80 1ST M tubing run with Jet Lube Run'n'Seal pipe dope Tubing suspended with diesel Comoletion MD TVD Tubing Hanger 32' 32' 4-1/2", 12.6#/ft, 1ST-Mod Tubing Camco DB6 nipple 2100' 1829' 4-1/2", 12.6#/ft, IBT-Mod Tubing Camco KSG2- GLM (3.909" ID) 9970' 6776' 4-1/2", 12.6#Ift, 1ST-Mod Tubing (2) Baker S3 Packer wI millout extension 10050' 6813' 4-1/2", 12.6#/ft, 1ST-Mod Tubing (1) HES "XN" (3.725")-64.00 inc 10130' 6851' 4-1/2", 12.6#/ft, IBT-Mod 10' pup joint WEG 10142' 6856' TOC @ +1- 9670' MD I 6600' TVD (>20~ì8' MD above top Alpine) Cameo KBG-2 GLM (3.909" DRIFT ID) wI dummy Baker 83 Packer WI millout extension at +1- 10050' MDI 6813' TVD < 200' TVO from top of Alpine Well TD at 15992' MD I 7100' TVD Top Alpine C at 10699' MD 17003' TVD 7" 26 ppf L -80 BTC Mod Production Casing @ 10813' /7015' TVD @+I- 85.50 CD1-20 DRILLING FLUID PROGRAM SPUD to Intermediate hole to 7" Production Hole 9-5/8"surface casing casing point - 8 %" Section - 6 1 18" point - 12 %" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 9.0-9.6 ppg PV 10 - 25 10 -15 YP 20 - 60 15 - 25 25 -30 Funnel Viscosity 100 - 200 Initial Gels 4-8 1 0-1 5 10 minute gels <18 12-20 API Filtrate NC - 10 cc I 30 min 4 - 12 cc/30 min (drilling) NA HPHT Fluid Loss at 160 12-14 cc/30 min PH 8.5- 9.0 9.0 -10.0 9.0-9.5 KCL 6% Oil Iwater ratio Surface Hole: A standard high viscosity fresh water I 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 I 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 well bore 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. ~' '-- Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD1-21L 1 will be the closest well to CD1-20. Well separation is 9.9' @ 300' MD. Accounting for survey uncertainties, the ellipse-to-ellipse separation is 4.6' @ 300' MD. Injection well CD1- 19A is also close to CD1-20 with 9.6' of separation @ 325' MD and ellipse-to-ellipse separation of 4.5' @ 325' MD. Drillina 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 CD1-20 will be injected into a permitted annulus on CD2 pad or the class 2 disposal well on CD1 pad. The CD1-20 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 CD1-20 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 potablelindustrial 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 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 85% of 85% of 00 (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-80 3 BTC-Mod 5,410 psi 4.599 psi 7,240 psi 6,154 psi Alpine: CD1-20 Procedure Procedure 1.

Since this is an injector, I will need information on the wells that penetrate the Alpine within 1/4 mile radius of the entry of CDI-20 into the Alpine and continuing along the planned well path to TD. Our preliminary look indicates that Bergschrund 2 and 2A lie within the area and that portions of CDI-26, 1-27 and 1-16 may be in that area as well. I would appreciate your getting with the directional planners to "draw" the plot. Please give me a call on Monday and we can discuss.

Conoc~illips November 24, 2004 Alaska Oil and Gas Conservation Commission 333 West ¡th Avenue, Suite 100 Anchorage, Alaska 99501 Re: Application for Permit to Drill CD1-20 Dear Sir or Madam: ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an onshore injection well from the Alpine CD2 drilling pad. The intended spud date for this well is December 15th, 2004. It is intended that Doyon Rig 19 drill the well. The intermediate section of CD1-20 will be drilled and landed in the Alpine sand ' horizontally; 7" casing will then be run and cemented in place. CD1-20 will be completed as an open hole injector. ' 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 42 wells drilled on CD1 pad and 43 wells drilled on CD2 pad with no significant indication of gas or shallow gas hydrates. While drilling two surface hole sections (CD1-07 and CD1- 46) this year, mud logging services were used and there were no significant indications of gas. One section of well CD1-07 showed up to 754 units of gas in the depth interval from 1390 to 1420 ft md. There were no measured gains in mud pit volumes associated with the gas. It is also requested that the packer placement requirement be relaxed to place the packer 200 ft TVD above the Alpine formation. This will place the completion at a maximum inclination less than 65 degrees, and allow access to the completion with standard wireline tools for future intervention.
