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 M.J.

This application is not approved. Mr. Vern Johnson's message of August 9, 2005 informed the Commission that pump-in testing had determined that the sub-surface disposal pressure would likely exceed the original formation integrity test making the well unsuitable for annular disposal. As provided in AS 31.05.080, within 20 days after written notice of this decision, or such further time as the Commission grants for good cause shown, a person affected by it may file with the Commission an application for rehearing. A request for rehearing is considered timely if it is received by 4:30 PM on the 23rd day following the date of this letter, or the next working day if the 23rd day falls on a holiday or weekend. A person may not appeal a Commission decision to Superior urt unless rehearing has been requested.

It is expected that annular disposal operations will resume at CD2 after an assessment and revision of operational procedures and guidelines. CD2-20 is a preferred candidate for disposal due to the fact that it has not been used for disposal yet, and the surface casing shoe is +/- 2000 ft from the surface casing shoe of the next well to be drilled (CD2-02).

This document examines the pertinent information for the well and reco mends approval of ConocoPhillips' request. --No unusual events were reported while drilling the surface --Surface casing was cemented to surface. Approxim ely 115 bbls of cement was circulated to surface. The net cement remaining in th surface hole was 430/0 XS of the calculated hole volume. --On the initial leak off test, it was not possible t pump into the well at 16.0 EMW. The pressure declined during the observation pe od to 15.8 EMW. The initial leak off indicates that the surface casing shoe is well ce ented. --No problems are reported drilling the inter ediate hole. The 7" casing was run and successfully cemented. The?" was recipro ated. Some lost returns was experienced while cementing. --An injectivity test down 9-5/811 x 7" annulus was conducted. Pressure steadily increases until the break at 15.4 EM . Pump in varied between 14.3 and 15.4 EMW. During the observation period, the ressure declined to 14.1 EMW. The lower EMW of the pump in test indicates that t e planned disposal should be conducted at EMWs below that of the shoe integrity. --CPA provided a listing of all urface casing shoes within ~ mile of CD2-20. There are a total of 19 wells within ~ mile of the surface shoe. The nearest well is CD2-12 about 300' distant. CD2-1 was approved for AD in late December 2003. There are 4 other wells between 45 - 900' away with 2 of the wells having been approved for AD. The remaining well are in excess of 900' distant. An examination of the files did not reveal any problem at would preclude granting CPA's request for CD2-20.

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 115 bbls of cement was circulated to surface. The net cement remaining in the surface hole was 430/0 XS of the calculated hole volume. --On the initial leak off test, it was not possible to pump into the well at 16.0 EMW. The pressure declined during the observation period to 15.8 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. Some lost returns was experienced while cementing. --An injectivity test down 9-5/8" x 7" annulus was conducted. Pressure steadily increases until the break at 15.4 EMW. Pump in varied between 14.3 and 15.4 EMW. During the observation period, the pressure declined to 14.1 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 CD2-20. There are a total of 19 wells within ~ mile of the surface shoe. The nearest well is CD2-12 about 300' distant. CD2-12 was approved for AD in late December 2003. There are 4 other wells between 450' - 900' away with 2 of the wells having been approved for AD. The remaining wells are in excess of 900' distant. An examination of the files did not reveal any problem that would preclude granting CPA's request for CD2-20. Based on examination of the submitted information, I recommend approval of ConocoPhillips' request for the subject well. t::~ Sr. Petroleum Engineer July 28,2004 G:\common\tommaunder\Well Infonnation\By Subject\Annular Disposal\040728--CD2- 20.doc ) ) ConocoPhillips Alaska, Inc.

It is intended to begin annular disposal operations on CD2-20 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; CD2-10 Further details regarding wells on CD2 pad within Y4 mile radius should be on file at the AOGCC. The initial annular LOT (15.4 ppg) and occurred at a lower equivalent mud weight than the casing shoe test (16.1 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.

P.O. Box 100360 Anchorage, AI< 99510 Re: Colville River Field CD2-20 ConocoPhillips (Alaska), Inc. Permit No: 203-105 (revised) Surface Location: 1766' FNL, 1539' FEL, SEC. 2, T11N, R4E, UM Bottomhole Location: 2631' FNL, 668' FEL, SEC. 27, T12N, R4E, UM Dear Mr. Alvord: Enclosed is the approved revised application for permit to drill the above referenced development well. This revision was necessary due to ConocoPhillips desire to extend the permitted total depth by more than 500' in a well with drilling operations underway. 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. 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 terms and conditions of this permit may result in the revocation or suspension of the permit. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test. Contact the Commission's North Slope petroleum field inspector at 659-3607 (pager). Sin~~~,.~...\' _ .

ConocoPh'illips Memo To: Alaska Oil and Gas Conservation Commission From: Zane Kuenzler cc: Winton Aubert Date: 7/11/2003 Re: CD2-20 Extension Dear Sir or Madam: CD2-20 is a horizontal well currently being drilled in the Alpine formation. This well was originally planned for 13284' MD and 7072' TVD, however sands of higher quality than expected were encountered while drilling the open-hole horizontal section. As a result the well was extended to 14570' MD and TVD of 7103'; with verbal approval to proceed past the 500' limit (20 MC 25.015) given by Winton Aubert of the AOGCC on 7/9/2003. Please find attached the required Permit to Drill (form 10-401), a revised directional plan with new bottom hole locations and anti-collision information, and an updated schematic. Should anything further be required feel free to contact me. Best Regards, Z"-r/ ~ç _ ! l7'~¡(~ Zane A.

I \.,~ i .4' i"~_ Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD2-19 will be the closest well to CD2-20. Well separation is 10.1 ft at 300 ft MD. Accounting for survey uncertainty, the ellipse-to-ellipse separation is 4.7ft at 300 ft MD. Drillinq 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 CD2-20 will be injected into a permitted annulus on C02 pad or the class 2 disposal well on CD1 pad. The CD2-20 surface/intermediate casing annulus will be flushed with 300 bbls of fresh water prior to freeze protecting with diesel to 20001 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 CD2-20 form 10-403, Application for Sundry Operations, will be filed. Annular pumping of fluids occurring as a result of 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). The 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 85°k 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-80 3 BTC-Mod 5,410 psi 4,599 psi 7,240 psi 6,154 psi , ') ) CD2-20 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 .....121,4" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 9.0-9.3 ppg PV 1 0 - 25 15 -20 YP 20 - 60 15 - 25 18 - 25 Funnel Viscosity 100 - 200 Initial Gels 4-8 N/A 10 minute gels <18 9-12 API Filtrate NC - 10 cc / 30 min 4 - 12 cc/30 min (drilling) N/A HPHT Fluid Loss at 160 4.0-5.5 PH 8.5 -9.0 9.0 -10.0 N/A Electrical Stability +800Vts Oil/W ater Ratio 80/20 Suñace 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 wellborestability. . 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 flashpoint (>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. . JiJ('lr:~~, J /.;, ~i,; ;' " i.~ ..

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 ]D' Where: ASP = Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in Ib/gal 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] D = [(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.
