The plan is to secure the well and a procedure for the secure has already been distributed. However,to limit the amount of freeze protection fluid removed from the IA,CPAI may allow the IA pressure to exceed 2000 psi while waiting for the secure weliwork to occur. The well has 7", 26 lb/ft, L-80 grade production casing with a burst pressure rating of 7240 psi. Please let us know if you have any questions or disagree with this plan.

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 tor 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, \27# ~ Arend- ConocoPhillips Well Integrity Field Supervisor ~ :)GANNED MAR 2 8 2007 Attachment . . ConocoPhillips Alaska Inc.

Waste on well CD2-10 Dear Sir or Madam: ConocoPhillips Alaska, Inc. hereby requests that CD2-10 be permitted for annular pumping of fluids occurring as a result of drilling operations, per regulation 20 ACC 25.080. It is intended to begin annular disposal operations on CD2-1 0 approximately August 11, 2004. Please find attached form 10-403AD and other pertinent information as follows: 1. Annular Disposal Transmittal Form 2. Pressure Calculations for Annular Disposal 3. Surface Casing Description 4. Surface Casing Cementing Report & Daily Drilling Report during cement job 5. Casing and Formation Test Integrity Report (LOT at surface casing shoe). 6. Intermediate Casing Description 7. Intermediate Casing Cementing Report & Daily Drilling Report during cement job 8. Formation LOT on 9-5/8" x 7" casing annulus 9. Plan View of Adjacent Wells 10. List of wells on CDl pad and the lateral distance from the surface casing shoe. 11. Additional information regarding wells within Y4 mile radius, not already on file at AOGCC; CD2-20 Further details regarding wells on CD2 pad within Y4 mile radius should be on file at the AOGCC. The initial annular LOT (14.9 ppg) and occurred at a lower equivalent mud weight than the casing shoe test (16 ppg LOT). Therefore we conclude that waste will not migrate above the confining zone provided we do not inject with sustained surface pressures that will cause pressures at the surface shoe to be in excess of the shoe FIT/LOT. If you have any questions or require further information, please contact Vem Johnson at 265-6081, or Chip Alvord at 265-6120. ~:/~ ~ ~ìms'~ Drilling Engineer 7-~;Z-Y cc: CD2-1 0 Well File Chip Alvord Nancy Lambert Sharon Allsup-Drake ATO-1700 Anadarko ATO-1530 C)~~!G\~~/~L e e p.,(;>~ STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSION ANNULAR DISPOSAL APPLICATION 20 Me 25.080 1.

Lateral distance in feet, between surface casing shoes, in the X-V plane .. CD2-35 was drilled from an ice pad in early 1998. The 9-5/8" x T' annulus has not been permitted for annular disposal. ···CD2-33 B was a delineation well with a window milled out of 9-5/8" casing at 3840' MD (3062' TVD), shoe depth shown indicates window depth. It has not been permitted for annular disposal. .... As of 7-27 -04 Note that this sheet is not the definitive record e e Note to File CD2-10 (203-195...304-289) Colville River Unit (Alpine) ConocoPhillips Alaska, Inc Phillips has made application for annular disposal for the subject well. This document examines the pertinent information for the well and recommends approval of ConocoPhillips' request. --No unusual events were reported while drilling the surface hole of the well. --Surface casing was cemented to surface. Approximately 114 bbls of cement was circulated to surface. The net cement remaining in the surface hole was 71 % XS of the calculated hole volume. --On the initial leak off test, it appears to have been possible to pump into the well at between 16.0 and 17.1 EMW. A total of 2.3 bbls was pumped during this operation. The pressure declined during the observation period to 14.4 EMW. The initial leak off indicates that the surface casing shoe is well cemented. --No problems are reported drilling the intermediate hole. The 7" casing was run and successfully cemented. The 7" was reciprocated and no lost circulation was reported. --An injectivity test down 9-5/8" x 7" annulus was conducted. Pressure steadily increases until the break at 14.9 EMW. Steady pump in occurs at 14.9 EMW. During the observation period, the pressure declined to 13.8 EMW. The lower EMW of the pump in test indicates that the planned disposal should be conducted at EMWs below that of the shoe integrity. --CPA provided a listing of all surface casing shoes within % mile of CD2-10. There are a total of 9 wells within % mile of the surface shoe. The nearest well is CD2-06 about 190' distant. CPAI has not applied for AD on CD2-06. The initial and pump in tests (16.0 and 15.1 respectively) indicate that the surface casing is well cemented There are 2 other wells between 420' - 640' away with the remainder lying beyond 840'. 5 of these wells have been approved for AD. An examination of the files did not reveal any problem that would preclude granting CPA's request for CD2-1 o. Based on examination of the submitted information, I recommend approval of ConocoPhillips' request for the subject well. ~~V¡~ "- Tom Maunder, PE Sr. Petroleum Engineer July 28, 2004 G:\common \tommaunder\ Well Infonnation\By Subject\Annular Disposal\040728--CD2- 10.doc .

This permit to drill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. The proposed TD of the CRU CD2-1O production well in Section 26, T12N, R 4E, UM violates Rule 3 of CO 443 by extending closer than 500' from exterior boundary of the Alpine Oil Pool. A spacing exception will be required. Rule 10 of CO 443 allows the Commission to grant such an exception administratively. Alternatively, ConocoPhillips may make application to the Commission to amend CO 443 to include Section 23 in the affected area. ConocoPhillips may drill the CD2-10 well, but the well may not be produced until an exception is granted or CO 443 is amended to include Section 23 in the affected area. ConocoPhillips assumes the risk that the exception or amendment may not be authorized. The permit is approved subject to full compliance with 20 AAC 25.055. Approval to perforate and produce is contingent upon issuance of a conservation order approving a spacing exception. ConocoPhillips (Alaska), Inc. assumes the liability of any protest to the spacing exception that may occur. Colville River Field CD! Pennit Number 203-195 December 2, 2003 Page 2 of2 . Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the tenns and conditions of this pennit may result in the revocation or suspension of the pennit. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test.

ORIGINAL Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD2-12 will be the closest well to CD2-10. Well separation is 12.97 ft at 550 ft MD. Accounting for survey uncertainty, the ellipse-to-ellipse separation is 2.93 ft at 550 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 Pumpinq Operations: Incidental fluids developed from drilling operations on well CD2-10 will be injected into a permitted annulus on C02 pad or the class 2 disposal well on CD1 pad. The CD2-10 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 CD2-10 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 below the base of the Schrader Bluff Formation (C-40). These 300-400' 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 85% of 850/0 of OD (ppf) Grade Range Type Collapse Collapse Burst Bu rst 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 t; ;i~r, .;~e~¡, fÐ.,'/ .'¡/:,I::. 0,,',,' ~ N JÄ I '~!: ~:l) ~,:, ~ 0 ~ ø !.".., CD2-10 DRilLING FLUID PROGRAM ) ) SPUD to Intermediate hole to 7" Production Hole 9-5/8"surface casing casing point - 8 Y2" Section - 6 1 18" point - 12 14" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 8.1-8.8 ppg ......

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 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. ORIGINAL CD2-10 PRESSURE INFORMATION AND CASING DESIGN (per 20 ACC 25.005 ( c ) (3,4) and as required in 20 ACC 25.035 (d) (2)) The following presents data used for calculation of anticipated surface pressure (ASP) during drilling of this well : Csg Setting Fracture Pore Casing Size Depth Gradient pressure ASP Drilling (in) MDfTVD(ft) (Ibs.

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 Iblgal 0.052 = Conversion from Ib./gal to psi/ft 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) = 1081 - (0.1 x 2390') = 842 psi 2. Drilling below surface casing (9 5/8") ASP = [(FG x 0.052) - 0.1] D = [(14.5 x 0.052) - 0.1] x 2390 = 1563 psi OR ASP = FPP - (0.1 x D) = 3214 - (0.1 x 7102') = 2504 psi 3. Drilling below intermediate casing (7") ASP = FPP - (0.1 x D) = 3204 - (0.1 x 7080') = 2496 psi I.

(CPAI) understands the subject development wells can be drilled to locations outside the Alpine Participating Area but cannot be used as injectors or producers until the following two things occur: 1) The injection order is amended to include the pertinent tract(s) and 2) Conservation Order No. 443 is amended to include the pertinent tract(s) or an exception(s) to 20 AAC 25.055 is obtained. Based on such understanding, CPAI proposes to proceed with the drilling of the wells while working to concurrently amend the injection and conservation order. Please kindly advise if this is not AOGCC's understanding. Thanks, again, for your prompt assistance and guidance on this matter. Steve, Soria, Dora I wrote: Sincerely, Steve Davies Yes, this is AOGCC's understanding.

After setting 7" intermediate casing, the horizontal section will be drilled and the well completed as an open hole producer. At the end of the work program, the well will be closed in awaiting completion of well work and facilities work that will allow·· the well to begin injection. Note that it is planned to drill the surface hole without a diverter. There have been 38 wells drilled on CD1 pad and 42 surface holes drilled on CD2 pad with no significant indication of gas or shallow gas hydrates. All of the wells on CD2 have surface casing shoes within a 2000' radius of the planned surface casing shoe of CD2-10. 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.
