This log was run to assess the condition of tubing with respect to internal corrosive and mechanical damage. The caliper recordings indicate the 4.5 and 3.5 inch tubing appears to be in good to poor condition, with a maximum recorded wall penetration of 49% in a line of pits in joint 154 (4,871 feet).A significant wall penetration of 44% is recorded in an isolated pit in the vicinity of the concerned area, below GLM3, in joint 290 (9,066 feet). Other recorded damage appears as general corrosion. No significant areas of cross- sectional wall loss or I.D. restrictions are recorded throughout the tubing. 4.5 & 3.5 INCH TUBING - MAXIMUM RECORDED WALL PENETRATIONS : Description Percent Wall Penetratior, Line of Pits 49 154 4,871 Ft.

The well has 3-1/2" 9.3# L-80 tubing from surface to 9288'MD. The proposed fracturing treatment will place approximately 302k# 16/20 CarboLite in nine 0-8-PPA stages at 20-bpm. Proposed Procedure: Schlumberger Pumping Services: 1. Conduct Safety Meeting and Identify Hazards. Inspect Wellhead and Pad Condition to identify any pre existing conditions. 2. Ensure all Pre-frac Well work has been completed and confirm the tubing and annulus are filled with a freeze protect fluid to 2,000' TVD. 3. Ensure the 10-403 Sundry has been reviewed and approved by the AOGCC. 4. MIRU 6 clean insulated Frac tanks, with a berm surrounding the tanks that can hold a single tank volume plus 10%. Load tanks with 100° F seawater (approx. 2679 bbls are required for the treatment with breakdown, maximum pad, and 450 bbls usable volume per tank). 5. Ensure lift plan is reviewed and signed prior to RU of Frac equipment requiring lifts. 6. MIRU Stinger Tree Saver Equipment and SLB Frac Equipment. 7. PT Surface lines to 9,000 psi using a Pressure test fluid. 8. Test IA Pop off system to ensure lines are clear and all components are functioning properly. 9. Pump the 108 bbl breakdown stage (linear gel) according to the attached excel SLB pump schedule. Bring pumps up to maximum rate of 20 BPM as quick as possible, pressure permitting. Slowly increase annulus (IA) pressure from 2,500 psi to 3,500 psi as the tubing pressures up. Ensure sufficient volume is pumped to load the well with Frac fluid, prior to shut down. 10. Perform a hard shut down, Obtain ISIP and fluid efficiency estimates. 11. Pump the Frac job by following schedule @ 20 bpm with a maximum expected treating pressure of 3445 psi. Stage 1 • 450 bbl Schlumberger fluid Pad • 170 bbl Schlumberger fluid w/ 1 PPA • 180 bbl Schlumberger fluid w/2 PPA • 210 bbl Schlumberger fluid w/ 3 PPA • 220 bbl Schlumberger fluid w/4 PPA • 260 bbl Schlumberger fluid w/5 PPA • 280 bbl Schlumberger fluid w/6 PPA • 260 bbl Schlumberger fluid w/ 7 PPA • 260 bbl Schlumberger fluid w/ 8 PPA • Flush with 91 bbl of linear fluid and freeze protect • Total Sand: Approx. 301,506-lb of 16/20 CarboLite Proppant 12. Monitor the surface pressure fall-off at the end of the job for 30 minutes, if the well does not screen out. 13. RDMO SLB Equipment. Freeze Protect the tubing and wellhead if not able to complete following the flush. 14. Well is ready for Post Frac well prep for flowback (Slickline and possibly CTU). Cement Evaluation of CD2-23 and wells within '/4 mile of CD2-23 CD2-23: 7" Casing cement job was pumped on 7/12/2002 as designed, indicating competent cement operations. The cement pumped was 15.8 ppg Class G cement, displaced by 10 ppg mud. The plugs were bumped on both stages to 1000 psi and 2000 psi respectively, floats held. Full returns were observed during the job. CD2-02: 7" Casing cement job was pumped on 8/10/2005 as designed, indicating competent cement operations.

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 - 22ß , 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, '»# ¡:; Arend- ConocoPhillips Well Integrity Field Supervisor ~ Attachment . . ConocoPhillips Alaska Inc.

The pertinent information for the wells has been examined and the following determinations made. SURFACE HOLE AND SURFACE CASING --No unusual events were reported while drilling the surface holes of any well. --Surface casing in all wells was cemented to surface. The attachments to the applications note that various amounts of cement were circulated from the wells. The actual pumped volumes were reviewed using the spreadsheet and the XS volumes left in the hole.were calculated to range from a low of 50% to a high of 1500/0. INITIAL LEAKOFF TESTS --Initialleakoff tests were conducted on all wells. It was not possible to pump into any well with slightly more than 16 ppg EMW applied. --The leak off pressure plot of CD2-23 is offset to the left of the casing pressure plot. The leak off plot does exhibit essentially linear response when pumping begins in contrast to the casing pressure plot. Beyond 10 strokes the casing pressure shows linear response and the slope of the linear section is similar to that of the leak off plot. It appears that some amount of air was in the mud present in the casing or drill pipe during the casing test --The leak off pressure plots of CD2-38 and CD2-41 essentially overlay the casing test pressure plot. --The leak off pressure plot of CD2-19 lies slightly beneath the casing pressure plot. PRODUCTION HOLE AND PRODUCTION CASING --No unusual events were reported while drilling any 8-1/2" hole section. --7" casing was successfully run and cemented in each well. SUBSEQUENT INJECTION TESTS M:\tommaunder\Well Infonnation\By Subject\Annular Disposal\030422-CD2 AD.doc ( --Subsequent injectivity tests were done down the 9-5/8" x 7" annuli of each well. In each case the formation failures were lower than the than the stabilized SI pressures from the initialleakoff tests. PROXIMATE WELLS Proximity analyses to identify any wells within 1/4 mile radius were performed for each well. CD2-23 CD2-19 CD2-38 CD2-41 There are 15 existing wells within 1/4 mile of the surface casing shoe. The nearest well is CD2-15, 205' distant. Annular disposal has been approved and successfully. conducted in 11 of the wells including CD2-15. Annular disposal is recommended for the other wells analyzed in this document. There are 23 existing wells within 1/4 mile of the surface casing shoe. The nearest well is CD2-28, 153' distant. Annular disposal has yet to be requested in CD2-28, although there is nothing in the LOT information that would preclude approving such a request. Annular disposal has been approved and successfully conducted in 11 of the remaining wells and is recommended for the 3 other wells analyzed in this document. There are 20 existing wells within 1/4 mile of the surface casing shoe. The nearest well is CD2-36, 173' distant. Annular disposal has yet to be requested in CD2-36, although there is nothing in the LOT information that would preclude approving such a request. Annular disposal has been approved and successfully conducted in 11 of the wells and is recommended for the 3 other wells analyzed in this document. There are 23 existing wells within 1/4 mile of the surface casing shoe. The nearest well is CD2-38, 279' distant. CD2-38 is analyzed in this document and is recommended for annular disposal. . Annular disposal has been approved and successfully conducted in 13 of the wells and is recommended for the 3 other wells analyzed in this document. Based on examination of the submitted information, I recommend approval of Phillips' requests for the subject wells. ba~~ Sr. Petroleum Engineer April 22, 2002 M:\tommaunder\Well Infonnation\By Subject\Annular Disposal\030422-CD2 AD.doc aOd-J3Lf !fd.7¥ WELL LOG TRANSMITTAL To: State of Alaska Alaska Oil and Gas Conservation Comm.

The 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. A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis of the week's activities and is exclusively for the Commission's internal use. 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 Adn1Înistrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. In accordance with 20 AAC 25.005(f), all records, data and logs acquired for the pilot hole must be clearly differentiated in both name CD2-23PH and API number 50-103-20425-70 from records, data and logs acquired for well CD2-23. Please note that any disposal of fluids generated from this drilling operation which are pumped down the surface/production casing annulus of a well approved for annular disposal on CD2 pad must comply with the requirements and limitations of 20 AAC 25.080. Approval of this permit to drill does not authorize disposal of drilling waste in a volume greater than 35,000 barrels through the annular space ofa single well or to use that well for disposal purposes for a period longer than one year. Permit No: 202-134 June 26, 2002 Page 2 of2 Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test.

J =\ ~ " R'I I L ( Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25J50 (b) is provided in following attachments. CD2-22 will be the closest well to CD2-23, 8.8' at 400' 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 Pumping Operations: Incidental fluids developed from drilling operations on well CD2-23 will be injected into a permitted annulus on CO2 pad or the class 2 disposal well on CD1 pad. Incidental fluids to include oil based mud using mineral oil as the base fluid. The CD2-23 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. We request that CD2-23 be permitted for annular pumping of fluids occurring as a result of drilling operations, per regulation 20 AAC 25.080. 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 TVD) + 1,500 psi = (12.0 ppg) * (0.052) * (2391') + 1,500 psi = 2,992 psi = 1,082 psi Pore Pressure / Therefore Differential = 2992 - 1082 = 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°/Ó 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 / ,I 7" 26 L-80 3 BTC-Mod 5,410 psi 4.599 psi 7,240 psi 6,154 psi I ,JRII L CD2-23 DRilLING FLUID PROGRAM Density PV YP Funnel Viscosity Initial Gels 10 minute gels API Filtrate HPHT Fluid Loss at 160 PH Electrical Stability Oil Iwater ratio Suñace Hole: SPUD to Intermediate hole to 7" 9-5/8"surface casing casing point - 8 Y2" point -12 14" / 8.8 - 9.6 ppg I 20 - 60 100 - 200 Production Hole Section - 6 1/8" 9.6 - 9.8 ppg / 10 - 25 15 - 25 9.1 ppg / 15 -20 18 -25 4-8 <18 NC - 10 cc I 30 min 4 - 12 cc/30 min (drilling) NA 9-12 NA 4.0-5.5 NA +800Vts 80/20 8.5-9.0 9.0 -10.0 . A standard high viscosity fresh water I gel spud mud is recommended for the surface interval. Keep flowline viscosity at :!: 200 seclqt 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 wellbore stability. Production Hole Section: The horizontal production interval will be drilled with a 80/20 oillwater ratio M-I Versa-Pro mineral oil based drill-in fluid. The base fluid will consist of high flashpoint (>200 F) mineral oil with 250/0 by weight calcium chloride as the internal phase. Calcium carbonate bridging material will be added to minimize formation damage. 0 I Colville River Field CD2-23PB 1 Pilot Hole - Prior to Sidetracking - - Updated 6/21/2002 RKB - GL = 371 Wellhead ~. .... 16" Conductor to 1141 ~ 9-5/8" 36 ppf J-55 BTC ..

It is intended that Doyon Rig 19 drill the well. The well CD2-23PB1 will be drilled to penetrate the Alpine sand at approximately 44.70 inclination to log and evaluate the Alpine interval. The well will be plugged back +1- / 900ft with two cement plugs and then kicked off and drilled to horizontal in the Alpine sands. 7" casing will then be run and cemented in place. The rig will drill out the 7" float equipment and the 6-1/8" horizontal section will be drilled with oil based mud u~ng mineral oil as the base fluid. CD2-23 will be completed as an open hole producer. At the end of the work program the well will be shut in awaiting surface connection. ./' Note that it is planned to drill the,-urface hole without a diverter. There have been 38 wells drilled on CD1 pad and 19 wells 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 1600' radius of the planned surface casing shoe of CD2-23. ./ 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 10-401 Application for Permit to Drill per 20 ACC 25.005 (a). 2.
