The closure applications provided the required information describing the history of the reserve pit(s), the present condition of the reserve pits(s), results of any required water sampling and an assessment of the potential risks posed by the drilling waste to human health and the environment. At these locations, the reserve pits-have been backfilled and there is no exposed drilling waste. ADEC coordinated review of the closure requests with the appropriate land owners/managers. ... Public notice requesting comments on the closure requests was publiShed September 20 and 21, 2001 in the Anchorage Daily News and posted on the state web site September 21,2001. No public comments objecting to closure approval were received .in response to this public notice. ADEC has determined that the reserve pits at these sites meet the closure requirements of 18 AAC 60.440. Closure Approval Under authority of 18 AAC 60.440 (j), ADEC grants permanent cloSure approval 'to Phillips Alaska Inc. for the inactive reserve pits at the following two' sites: · · Well Name API Number MTRS Landowner North Fork Unit 41-35 50-231-10004-00 Sec. 35 T04 S,R 014 W, SM Private KRU Ugnu SWPT-I 50-029-20914-00 Sec 7, T 12N, R10E,UM DNR Phillips Alaska, Inc.

Closure for the pad as a whole (if required) must be coordinated between' the owner/operator and the appropriate land owner/manager. Any person who disagrees with any portion of this decision may request an adjudicatory hearing in accordance with 18 AAC 15.200-310. The request should be mailed to the Commissioner of the Department of Environmental Conservation, 555 Cordova Ave. Anchorage, AK 99501.

He was unable to recommend location clearances for three wells: Ugnu SWPT #1, West Sak River State #16, and West Sak River State #17. in his report on these wells, Mr Spaulding noted that "the area around the location marker had sunk down about 2' below pad grade;" the pit liners had not been removed; and pits had not been filled.

Field Sunday Feb. 28,1993: I traveled this date to AAI's Ugnu SWPT No. 1 well to witness the first phase of the cementing program for surface abandonment. I met Tom Anglen AAI rep. at the location and witnessed the perforation of the 10 3/4" csg, at 270' MD and the circulation of warm diesel down the 10 3/4" csg and back to surface through the 13 3/8" csg. As per the AAI cementing program, I reviewed on location, after circulating and cleaning the 10 3/4" csg and 13 3/8" annulus a Cast Iron Bridge Plug would be set at 300' +/-, cement would then be pumped down the 10 3/4" csg and through the perforation back to surface until returns were received out the 2" annulus valve on the tree. Due to the ongoing BOPE test at Nabors Rig 22E on the Jones Island exploratory well, I was unable to witness the setting of the bridge plug and the cementing operations. I was however updated daily by Mr. Anglen about the progress of the operation. I was given the following information regarding the surface cement plug; on 3/1/93 250 sx 49 bbl's, of 14.7 ppg, Haliburton Canadian Permafrost "C" cmt. was circulated through the perforation to surface. Tuesday March 2, 1993: I traveled to the Ugnu location and witnessed the removal of the well head and the cutting of the 20", 13 3/8" and 10 3/4" casings. I verified that there was hard cement in all casing strings and that all casing strings were cutoff approximately 6' below the surface. Thursday March 4, 1993: I traveled back to the location this date, while enroute to the Till No. 1 exploratory well, and found the marker post to be in compliance with 20 AAC 25.125. I stopped by the KCS pad in Kuparuk and collected four pictures showing the cutoff casings and surface cement, the final cement grout, the blind plate with gussets, the abandonment marker post, and backfilled cellar area.

It is anticipated that production casing temperatures will average ?[21.2°F~, from TD to surface. There is a possibility that free water could be left within the ±200' plug of 10-3/4" x 13-3/8" shoe cement. If this water is unable to escape through the cement when heated, it will generate collapse for¢e~, on ,th,e,1.0-3,/4" _and burst forces on the 13-3/8". We wish to design the casing program to increase the chances of 13-3/8 burst. 13-3/8", 54.5#/ft, K-55, 8rd STC casing would be ran from 1760' TVD to 2200' TVD. The rest of the casing program remains unchanged. Permafrost depth is estimated at 1680' TVD. Therefore, no "unapproved" casing will be ran through the permafrost. If the permafrost base comes in' deeper than predicated, the 54.5#/ft K-55 will be ran on the bottom 440' of the surface casing string. In no instance will the 54.5#/ft, K-55 be ran deeper than 2600' TVD. Alaska Oil & Gas Cons, Commission Anchorage 14.

Extended Estimated T0C - 2200'MD ARCO Alaska, Inc., proposes to drill an Exploratory Test well .to 4000' MD. A 20" diverter will be installed on the 20" conductor while drilling on the 17-1/2" surface hole. Logs will be r~ln in the 17-1/2" hole. A 13-5/8" 5000 RSRRA BOP stack will be installed and tested to 3000 psi (1800 psi for the annular). The BOP equipment will be operationally tested each trip, and pressure tested each week. The production hole will be drilled 12-1/4", and logged. If warranted the hole will be opened up to 15", 10-3/4" casing set, and the West Sak and Ugnu Zones will be cased hole tested. The well will be left susPended in accordance with AOGCC requirements. Non-freezing fluids will be left in uncemented annuli through the permafrost. RECEIVED F E B - 4 t983 23.
