Item 1a: Classification of Service wells: Gas injection, water injection, Water-Alternating-Gas Injection, salt water disposal, water supply for injection, observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI (Top of Producing Interval). Item 8: the Kelly Bushing elevation in feet abour mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). Item 20: True vertical thickness. Item 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-in, Other (explain). Item 27: If no cores taken, indicate "none".

Roby Review of application On March 15,2006, the Commission received an Application for Sundry Approval, Sundry Number 306-088, to plug and abandon well3S-23, Permit Number 203-045, in the Kuparuk River Oil Pool. The cover letter submitted with the application stated that the wellbore would be P&A'd so that the well could be redrilled as a horizontal well into the same sand. The letter also stated that current production is approximately 450 BOPD, Commission records indicate that current production is 323 BOPD. Commission records indicate that the current gas oil ratio is approximately 600 scf/stb and the producedV¡{ter cut is approximately 45%. Below is a current production plot for the subject well 1/'fI~Ra1dicn 1) mD 1JD 10 01 001 :lIB '" ¡¡; œ OOE The Commission has not received the related APD for the 3S-23A horizontal well that ConocoPhillips proposes to drill so I called Mr. Guy Schwartz to discuss their proposal. My main concerns were the potential abandonment of reserves and the location of the new well related to the existing wellbore. Mr. Schwartz informed me that the new wellbore would target the same fault block as the existing wellbore and in addition would target another fault block further to the South that is not currently being tapped. Based on my discussion with Mr. Schwartz I do not believe that the proposed action will cause a loss of recoverable reserves. Therefore, I recommend approval of Sundry Application 306-088. D.S.

After P & A the well will be sidetracked to new location 3S-23A. ' The attached P & A procedure outlines the basics steps including cementing the current well perforations, pulling tubing and 7" casing and kicking off the new well within a cement plug. . The overall objective of the project is to drill a single horizontal rotary sidetrack lateral from the 3S-23 well bore to develop "C" sand reserves in the southwest edge of the 38 drill site. This horizontal lateral will be placed due south of the 3S-23 and drilled in a southerly direction. The production hole will be 5,561 feet in length with the horizontal lateral length from landing to TO will be 5,247 feet. The current 3S-23 " completion, making 450 bopd, will not be retained The expected spud date is April 1 ,2006." If you have any questions or require any further information, please contact Jason Brink at 265-6419 or Guy Schwartz at 265-6958.

"O? 200J ~t (1as Cb ~~, Dear Mr. Maunder: Enclosed please find a spreadsheet with a short list of wells from the Kuparuk field (KRU). Each of these wells was found to have a void in the conductor by surface casing annulus. The voids were filled with cement to the top of the circulation ports in the conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place. The top-fill operation was completed on November 18,2003. Dowell-Schlumberger batch-mixed Arctic Set I cement to 15.7 ppg in a blender for each well. The cement was pumped from the bottom of the void to the top of the conductor on each well via high-pressure hose. The attached spreadsheet presents the well name, top of cement depth prior to filling, and the number of sacks used on each conductor. Please call Nina Woods or me at 907-659-7224, if you have any questions. :~~¡ MJ~ / ConocoPhillips Problem Well Supervisor Attachment :C.\- '\ ~ f'.AC~ «. ~'~f"'\. ~'" ~''-Q. ~t\.\-. +0 Cr ~ \ \ 'o",,-c- ~,. ö.*~~ b~ ~~ 'ž><..xc....<!O.<¡,si:...::. \ \....., ~~""«-"-~~ -\ö s.<;:,~.

This pennit to drill does not exempt you from obtaining additional pennits or approvals required . by law from other governmental agencies, and does not authorize conducting drilling operations until all other required pennits and approvals have been issued. In addition, the Commission reserves the right to withdraw the pennit 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 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.

Due to pressure depletion, the predicted reservoir pressure for 35-23 is predicted at 3395 psi at 5886' tvd, 0.58 psi/ft or 11.1 ppg EMW. The maximum potential surface pressure (MP5P) while drilling 35-23 is calculated using above maximum reservoir pressure, a gas gradient of 0.11 psi/ft, and the Kuparuk C sand target at 5886' tvd: MP5P =(5886 ft)*(0.58 - 0.11 psi/ft) = 2766 psi (B) data on potential gas zones; The well bore is not expected to penetrate any gas zones. and (C) data concerning potential calJ!:Jì2S of hole problems such as abnormally geo-pressured strata, lo~t circulation zones, and zones that have a propensity tor differential sticking; Please see Attachment 2 - Drilling Hazards Summary 5.

Drill out cement and 20' of new hole. Perform LOT. 6. Drill 8-1/2" hole to total depth according to directional plan. Run LWD logging equipment with GR, resistivity, and density-neutron. Run 7" 26# L-80 BTCM casing to surface and cement. Note: If significant hydrocarbon zones are present above the Kuparuk C sand, sufficient cement will be pumped for isolation in accordance with 20 AAC 25.030( d)(3)(C). 7. Run 3-1/2" 9.3#, L-80 8rd EUE 8rd-Mod completion assembly w/ SAB-3 permanent packer and PBR. Set packer 100' above top planned perforation, shear out of PBR, P/U tubing hanger, and land tubing. Pressure test tubing to 3500 psi. Pressure test 3 V2" x 7" annulus to 3500 psi. Burst shear valve for freeze protect. 8. Set TWC and ND BOPE. Install and pressure test production tree. 9. Freeze protect. Secure well. Rig down and move out. 10. Handover well to Operations Personnel. 14.

Increase mud weight / viscosity, High viscosity sweeps. Monitor fill on connections Circulate hole clean prior to trip. Proper hole fill (use of trip sheets), Pumping out of hole as needed. Watch return viscosity for signs of thinning. Increased mud weight/viscosity as needed. Prevent by keeping hole clean. If losses occur - reduce pump rates and mud rheology, use LCM M itiqation Strate~y Control with higher MW and proper drilling practices. Condition mud prior to trips. Monitor ECD's with PWD tool while drilling across pay interval. Pump and rotate out on trips as a last resort. Good drilling practices as documented in well plan. Periodic wiper trips. Do not leave pipe static for extended period of time. Follow mud weight schedule and do not fall behind. Stripping Drills, Shut-in Drills, PWD Tools, Increased mud weight as needed. Ensure adequate kick tolerance prior to drilling pay interval. Use PWD to monitor hole cleaning. Reduced pump rates, Mud rheology, LCM.

(Company Name) assumes the liability of any protest to the spacing exception that may occur. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones.
