The 7" x 9 -5/8" annulus was left with freshwater mud to surface. The gravel pad surrounding North Kuparuk St 26 -12 -12 will be reclaimed during the 2011 ice road season, so the 7" x 9 -5/8" annuli will be filled with cement and the casing will be cut off 3' below tundra level. The procedure below outlines the steps to perform the final operations to fill the 7" x 9 -5/8" annulus with cement and then cut the casing 3' below tundra level and install a subsurface marker plate. This work will begin January 25, 2011. Procedure to cut casing below tundra level of North Kuparuk St 26 - 12 - 12 for final abandonment: 1. Excavate around wellhead and prep site to cut off casing. 2. Cut off and remov the casing a minimum of 3' below original tundra level. 3. Remove fres drilling mud using 1" pipe from the 7" x 9 -5/8" annulus to 150' or as deep as possible. 4. Cement 7" x 9 -5/8" annulus to surface. 5. Fill any unfilled annuli to surface with cement. a.

The weather was generally poor with light to heavy snow showers, and 30 degrees with gusty winds. I was met at the Airport by Red i~.1orst of L~ukluk, who carried me to the [.!ukluk camp where I picked up the leased vehicle. I returned to the Gay Air~ays', Inc. office at Deadhorse to check with the operations pi lot Walt Frisch, and learned that a chopper would not be available until late afternoon and ! was .requested to check back about 5:00 Pi"1. i returned to the Mukluk camp where I ate lunch and topped off the two gas tanks in the vehicle before heading out west on the BP's '~spine road'' through the field. It is evident that a great deal of construction activity has been going on with new gravel maintenance roads being con- structed for field pipelines which wi Ii transport oil and gas from the wellheads at each development pad to the production stations. New culverts are being put in for better drainage of both lakes and rivers. Large stock pi les of pipe and equipment are being located close to where the work will occur in the field area. BP had at least three large stacks of pipe located in the field besides the main supply depot at ~.!ukluk's yard. BP has construction underway on the gravel pad for their new Base Cam~, which wi !! be about one rnile southeast of the GC-I production flow station. The Brinkerhoff Rig ~-~-~36 has been moved from F-pad back to A-pad over well #6 -: to comn-~ence resetting of ?he tubing and packer in that well. Portions of the rig and camp are still being moved. I drove to F-pad and took two pictures (attached, page 5) showing ~ Photo #1-1, Item #!, the well- head and sign of Well ??F--2 with Item #2, the reserve pit in. the background. Photo f~l--2 shows' Item #1, wellheads of F-I through 5; Item ~.!3 ~ortable mast and logging truck working on well 5F-6; and Item #4, pipe and drilling equipment stacked on edge of the pad. i also stopped at the old BP Central Pad-3 for Photo f.:'l-3 ~,~hich shows: Item #1, the open pit on the south side of the pad and Item #2, one of the fenced well ce l lars. I then drove to Prudhoe and proceeded to ARCO's DS #1 where I had noticed the drilling mast had been lowered on the Rowan rig. The rig had been ski dded~f-fof the #1--5 well to the very end of the pad and khmer L. Burreil -2- October 20, t972 the mast laid down. The rig does no+,. appear to be disrnantled for' moving off this location. I took two photos (page 6) of this developmenff- drill site. Photo #I-1 shows: Item #i, the permanent production buiidinfi over the wellhead on well #1; Item ~,.2, the well sign on the door of the bui ldin9. Photo #I--2 was taken from the road~ay east of the pad and snows: Item #1, the %~o well-houses over #1-1 and #1-3; Item #2 the wellheads of #1-2, #1-4 and #1-5; item !!3, the rig stacked at the south end of the pad and; Item #4, a test tank near well ~!i-4. I returned to Gay Helicopter's office at Deadhorse and waited for' the availibiilty of a helicopter. Finally at 6:30 P~..~ a helicop'ier was ready and even though it was quite late in the day ! decided to proceed with the inspection trip because no better conditions could be predicted for the next day. Well locations were inspected in the following order: i. Mobil - Hurl State #5-10_,13 .(Sec. 5, TION_, RI3E, U.M...) We reached the location at 6:46 PM, circled and landed, i took two photos on the ground (page 7). The first photo #1-1, is looking south past the wellhead toward the pit and shows: Item #1, the wellhead in a cellar; Item #2, the well sign; Item #3, rig si Ils and pi ling; Item #4, the reserve mud pit. - Photo #1-2 shows: Item #1, the wellhead; Item ;,'.z3, the rig sills and piling; Item #5, the '~rat hole" pipe next to the wellhead. The gravel was quite ~'rough~' and the location although free of any large materials would require considerable picking up to be clean of trash and debr i s. 2. Mob i I - Kupar_uk .S_tate #24- I I- ! 2 ...(~.e~c.. 24_,_ T I I N.,. R 1.2E ,. U .~I. ) This well has a large stack of mud pal lets on the east end of the pad and several other stacks of material near the welihe&d and along the west edge of the pad. The wellhead has a few sills around iff' sticking up through the gravel. Some boards and trash are scattered just off the northwest corner' of the pad. A drilling line is strung across the pad along with boards and sticks, an~ lots of small debris. I ."~2--I is looking to the southeast and took thre.e photos (page 8) here, ;,._ shows: Item #1, the wellhead in a cellar; Item //2 part of the open reserve pit; Item #3, a mud tank, a stack of barrels and a pile of rig si Ils. Photo #2-2 is a view to the southwest showing: Item ~,:~, three stacks of casing along the west edge of the pad; Item ~"5, an open ~:camp pit'";. Photo ~72-3 is a view to +,'he northeast across the northwest corner of the pad showing' Item #4, stacked casing; Item ~!6, a loading dock wiffh miscellaneous supplies; ltl-em #.7, the gravel road leaving the location to the north; Item #8, boards, trash and cable both on and off the pad. 3.

At least %.~o pits are still open, one to the east and one to the south. ! didn't see any well sign. I took three photos (page 9) here, #3-1 Iooki'ng to the south 'shows: Item the wellhead in the cellar; Item #2 what appears to be the reserve mud pit.

TI~ I~_RI_IE, There are no supplies left at this location, but it is obvious from ti~e dama.ged tundra around and off the northwest corner of this location tha~,~ proper care was not taken reguarding vehicle operation before or after breakup. There are quite a few posts or pi ling sticking up as much as three feet which are-off of the pad on the southeast corner. The reserve mud pit is to the south of the pad and it contained some wire rope on'the west side of the pit berm and a number of mud sacks in the pit along the east side. There is a large well sign at the east end of well location. ! took two photos at this location (page i0). Photo ~4-1 shows: Item #1, the wellhead; Item #2, the reserve pit; item #3, a welisign; Item #4, pi ling and sills used to support the rig; Item #5, a caved-in ';rat hole'~'. Photo #4-2 shows: Item #1, the wellhead; Item #2, the reserve mud pit; item #6, hoses, pipe and debris whlch are scattered around the location. 5. SOCAL- Kaverak Pt. #32-25 (~Sec. 2~, Ti3N, RIOE_;_~..~[,{.)~ Due to the lateness of the day and the heavy snow showers we required almost !0 minutes to locate this well. When we found it at 7:49 P['..~i it was too dark to take any more photos but I observed the following: I. The wellhead is contained by a plywood house which rests on the rig sills and pi ling; 2. There are several joints of pipe on the si Ils near the building; 3. The reserve mud pit is to the east side of the location; 4. A small well-test burn pit is to the southwest of the location; 5. A number of barrels are also stacked on the sills; 6. The pad is fairly clean except for the heavy pieces of Iron sticking out around the edge of the pit area; 7. Considerable junk and debris has been placed in the small burn p'it. 6. SOCAL- Simpson Lagoon #32--14A (Sec. 1,4~__TI3N., We found this well location lightly covered with snow and it was still 'snowing. it was too dark for pictures so I walked around the location and noted the follo',-~ing: i. The reserve mud pit was still open on the west side of the well; 2. The wellhead was covered by a plywood house; 3. The rig piling and sills were still in place; 4. The fuel area bem~s were still intact; 5. The reserve pit and around the pi lings contained trash and debris; 6. Part of the gravel on the east side of ~'he well was smooth; 7. On the sills near the wellhouse a great deal of material had been neatly stacked consisting of barrels, tubing and ti tubers. The nearby snow showers continued and we were unable to locate the SOCAL we I I ~ap-29E and after' hunting for a while I decided enough time had been spent and so we headed toward Deadhorse. 7. [,'!obi i - Kuparuk St. #7-11-12 (Sec. #7, TI IN, Ri2.E~,_ U.H.) As we flew toward Deadhorse we flew directly over this Mobil well and landed, even though the aircraft's landing lights had to be used. Tills location has: !. A reserve mud pit south of the well which H~.~er L. Burreli -4- October 17, 1972 contains some debris; 2.- A -~est pit off to the southeast which is sti !1 open with a large pi ie of gravel or excavated material pi led to the southside; 3. The wellhead has a weilsign; 4. Rig si Ils are still inplace in the gravel around the wellhead; 7. Except for a ladder laying near the wellhead the location appeared cleaner than most o'f Mobi Is I ocat ions. We returned to Deadhorse arriving at 8:30 PM after inspecting seven of eleven locations of two operators.

Present Condition of Well: In May 1970, the casing pressure ~,as found to be i000 psig (oil). The tubing pressure was found to be 1200 psig (gas). Approximately one week later the tubing was vented to the sump. The casing pressure vented when the tubing was vented. In June, Otis ran'a wireline tool into the hole to 311' where it stopped. Methanol was pumped into the tubing in an attempt to melt plug assuming it was ice. The wire linewas rerun and stopped again $ti'. Fresh water mud was left between the 9-5/8~ and 7" casing strings from surface down to the top of the squeeze at 3771'. ?nerefore~ it appears that either the 7" casing has collapsed against the tubing on both sides of the safety valve or that the safety valve is leaking and the 7" casing has collapsed against the tubing above the.~safety valve.

A. Access to this site shall be by all-season gravel road or by aircraft, with the exception that winter roads may be utitized when surface conditions are such that land damage will not result from such use. Prior to the beginning of drilling, a sump of sufficient size to contain all waste fluids will be constructed. This sump must be lined with materials impervious to oil and oil products at all seasons during the year. Prior to abandonment, of the site, the sump must be cleaned of all oil and covered. 3. The operator must dispose of all waste, including garbage, by burning, with non-combustible material end u'n-burned residue disposed of in a manner and in a location acceptable to the Alaska Department of Fish and Game, i.e., in some locations burial may be required, on others removal from the site may be necessary. 4. Sewage and waste water will be disposed of by lagooning or the cesspool-septic tank method. No stream or. body of water will have any sewage or waste water added to it. 5. The Habitat Biologist's Office, 1018 West International Airport Road, Anchorage, Alaska 99502, will be notified prior to closing of this location. cc: Hilliker Burrell Denton Company Is well to be located in a defined pool ................. ~ L~. 2.
