Dear Mr. Maunder: ~a~q ~~~ ~ ~~, i ~, ". `~,~- Enclosed please find a spreadsheet with a list of wells from the Kuparuk field (KRi~. Each of these wells was found to have a void in the conductor. These voids were filled with cement if needed and corrosion inhibitor, 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 was pumped August 15~` and 23rd 2009, and the corrosion inhibitor/sealant was pumped August 27~', 28;~ and 29~' 2009. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each conductor.

POOH 6400' of 3-1/2" tubing standing back tubing that is re-useable, lay down jewelry. PU 2" hollow carrier perf guns and blank spacer. RIH on 2-1/16" CS Hydrill and 3-1/2" drill pipe off racks. Place guns on depth and perforate 3-1/2" liner. Circulate brine to kill well. POOH laying down drill pipe and perf guns. Run 3-1/2" tubing and gas lift mandrels. Stab seals into tieback sleeve, space out, land tubing hanger. Pressure test tubing and annulus. ND BOPE. NU and test tree. Displace well with seawater. Freeze protect well with diesel. Lower Limit: 4 days No problems running perf guns or killing well. Expected Case: 7 days Upper Limit: 10 days Difficulties running perf guns or killing well. TJM 7/13/01 . . . . . 11.

Kuparuk Well 3H-18 SUNDRY NOTICE 10-403 REPAIR REQUEST 07/09/01 The purpose of this Sundry Notice is to notify the AOGCC of Phillips Alaska, Inc., intent to repair the tubing on Kuparuk well 3H-18 injector. The AOGCC was notified of a failed MIT on 1/3/01. Diagnostics showed the failed MIT was due to a leak in the tubing, but the leak rate was too small for traditional logging tools (0.36 gpm with 500 psi DP T x IA). A video log was performed on 7/8/01, which showed the leak in a tubing collar connection at 7010' md. No other leaks were found and the tubing appears to be in good condition. A 3-1/2" patch (1.81" ID, retrievable) will be set (centered) over the tubing collar leak @ 7010' md. An MIT will be performed on the casing to verify the repair integrity. Near-term plans for this well include conversion from water to gas injection (WAG service). PROPOSED ACTION PLAN Phillips proposes to use the following action plan for operation of this injector: 1. The well may be used for either gas or water injection (WAG); 2. Tubing / casing integrity must be maintained by installation and maintenance of a patch or other repair over the known tubing leak @ 7010'md to meet AOGCC MIT criteria; 3. Successfully MIT the casing / tubing after installation of the patch and after any future replacement or maintenance of the patch; 4. Perform an MIT every 2-years subject to standard test criteria ( 0.25 x tvd @ packer or 1500 psi minimum, whichever is higher); 5. Notify the AOGCC should MIT's or injection rates and pressures indicate further problems. NSK Problem Well Supervisor 06/23/01 ARCO Alaska, Inc.

The sidetrack was then geo-steered through the Kuparuk C and A sand to a total depth of 11,594'MD. Enclosed are the additional drilling reports (12/29/99 thrugh 12/31/99) you have requested for the 1R-22a sidetrack. Please call me at 265-6120 if you have any other questions regarding this matter.

Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole.

Anch0rag0 Dear Mr. Commissioner: Pursuant to a telephone conversation on 11/23/99 with Tom Maunder, discussing the minor changes to the approved well plan, we are submitting this revised directional survey and completion schematic for KRU 1R-22A. The revised directional survey reflects the RKB difference in changing rigs from Nordic 3 to Nabors 16E (Pool 6) and slight adjustment of the horizontal targets to smooth the doglegs. The proposed horizontal completion is now a cemented rather than slotted 3-1/2" liner. Also enclosed is the BOP schematic for Nabors 16E. As discussed with Mr. Maunder, these are not substantive changes to the bottom hole location or the completion and the attachments with cover letter could serve as addendum to the permit. Estimated start of this sidetrack is December 20, 1999. Sorry for any inconvenience this may have caused. If there are any questions or additional information is required, please call Brian Noel at 265-6979. Sincerely, C.

Well Control: Well control equipment consisting of 5000 psi working pressure pipe rams, blind rams, and annular preventer will be installed. Maximum anticipated surface pressure is estimated at 2477 psi and is calculated using a gas column to surface with a maximum expected formation pressure in the Kuparuk of 3200 psi and a gas gradient of 0.11 psi/ft. Therefore, ARCO Alaska, Inc. will test the BOP equipment to 3500 psi. See attached BOPE schematic. Drilling Hazards: Lost Circulation: Overpressured Intervals: Other Hazards: The suspect lost circulation zones throughout the Kuparuk field are the K-10 and K-5 intervals. The sidetrack 1 R-22 A, will kick off out of the 7" casing above both the K-10 and K-5 intervals. Therefore lost circulation may be a significant problem in this well. The current cement bond log, on 1R-22, does not extend beyond 8,700' MD. Therefore, It is uncertain if cement exists behind 7" casing at the planned window depth. If the Formation Integrity Test will not hold the desired equivalent mud weight, a cement squeeze at the window could be performed. The kick-off point in 1 R-22 A is below any zones which would be of pressure concern prior to weighting up for the Kuparuk interval. None Directional: KOP: Max hole angle: Close approach: 6,504' MD / 4,492' TVD 91 ° (in sidetrack portion) No Hazards 57° (in original portion) Loc~clinc~ Program: Open Hole Logs: Cased Hole Logs: GR / Resistivity None Notes: All drill solids generated from the 1 R-22 A sidetrack will be hauled to CC2A in Prudhoe Bay for grind and inject. Incidental fluids developed from drilling operations will be hauled to the nearest permitted disposal well. KRU 1R-22 A GENERAL SIDETRACK PROCEDURE P&A WORK (Pre-Rig): 1. RU slickline unit. RIH and dummy off all GLM's. Pressure test 7" casing to 3500 psi for 30 min (chart test). 2. RU pump truck.
