Plug Test ARCO - PBU_-~_DS 35' Prudhoe Bay Field Friday, September 17,1993: I traveled to ARCO's DS 15 - 8 this date and witnessed the pressure test of a cement plug set above a CTU inflatable plug set at 9500 feet. The pressure was brought up to 1600 psi and held for 30 minutesJwith no loss of pressure. I departed the location at this time due to another job but [ talked to Mr. Selman, ARCO Rep., the next morning and he informed me that he ran in the hole with a bailer and incountered stringers of mud and cement from 7400 +-. He said he finally got to hard cement at 9007'. According to the well plan, the tubing will be cut off at 7700', the rig will move in, pull the tubing, then set a retainer and put 100 + feet of cement above it for a kick-off plug. Summary: I witnessed the pressure test of the perf. plug set on ARCO's DS15 Attachment: Copy of wire line report.

The original P&A procedure had planned to lay cement in the slotted liner and up to 300' above it. The coiled tubing, however, is predicted to be near its tensile strength at this depth and under cementing conditions. Approval of this revised procedure is requested: Plug and abandonment of the well by setting a through-tubing inflatable bridge plug in the 7" liner at 9500', and laying 300' minimum of cement on the plug. Since only Zone 1 will be open below the plug, zonal isolation will be achieved. The steps are as follows: 1. Notify an AOGCC representative prior to commencing plug-back operations. ,.. ~,l.~ 2.

This well is currently completed with a 4-1/2" slotted liner in a horizontal section. Plug and abandonment of the well will be performed with a coiled tubing cement squeeze in the slotted liner, including two to three hundred feet of cement above the liner top at 10,878' MD. Due to the high hole angle at the proposed cement plug, wireline will be unable to reach the top of cement for plug confirmation. A 1500 psi pressure test of the well will confirm cement integrity. Other options are to tag the cement with coiled tubing, or to bring the cement up to the point where wireline could reach it (an additional 1300',_+48 bbls cement). These options were not chosen due to their relatively high cost. The proposed P&A will be as follows: 1. Notify an AOGCC representative prior to commencing plug-back operations. 2. Lay a cement plug starting from PBTD of the slotted liner. Leave the top of cement 300' above the top of the slotted liner (100' required by State). 3. With an AOGCC representative on location to witness the operation, pressure test the well to 1500 psi. 4. Rig up electric line and cut the 4-1/2" tubing in the center of a full joint near 7700' MD. 5. Circulate the well over to seawater and freeze protect well with diesel to 20O0' MD. 6. Bleed any pressure from the tubing, inner annulus and outer annulus to zero. 7. Install a back-pressure valve. Remove the well house and flowlines. Level the pad and dig out the cellar. Prepare the pad for arrival of the rig. 8. Rig will set a bridge plug in the 9-5/8" casing at _+7650' prior to milling a 50' section at 7450' and setting a kickoff cement plug. Phil G.

THE ANALYSTS 4. BIT RUN SUMMARY Bit ~10 Drilled from 9423' to 9551'. This Smith F2 (extended nozzle) drilled at an average ROP of 100 ft/hr until a substantial increase in torque forced a trip out of the hole. The ROP dropped to 15 ft/hr before the trip was made. The casing shoe may have played some role in the torqueing. The bit was pulled in very good shape. T1/B2/GIN Bit 911 Drilled from 9551' to 10,1~0'. Another Smith F2 (extended noZzle) drilled at ROP's between 50 ft/hr and 200 ft/hr, averaging over 100 ft/hr for the 609 feet drilled. The gas increased primarily due to the increased ROP. As the conglomerates below 9700' were drilled, the fractured cherts were the primary cause of the trip at 10,160'. All drilling parameters went smoothly with the~bit coming out well used. T6/B5/G 1/4. Bit 912 Drilled from 10,160' to 10,982'. The last Smith F2 drilled well at an average of 90 ft/hr as the oil leg of the well was reached. Drill- ing went smoothly and the trip out was to change the bottom hole assembly for directional reasons. The bit was pulled in good shape. T2/B2/G 1/16. Bit 913 Drilled from 10,982' to 11,060'. A Reed FP51A was run into the hole~-a bit cOmparable to an F2, but without the extended nozzles. A decrease in efficiency of 20% was expected. The bit was only on bottom a short time when a downhole MWD tool failure ~caused the trip to put a new tool in the string. Bit 913 Rerun. Drilled from 11,060' to 11,345~. The sands began decreasing on this run and silty shales were encountered with the apparent basement being reached just below 11,165. One hundred eighty feet of basement were drilled to' ensure we were indeed out of the Sadleroch~t After 363' the bit still came out in good shape. T2/B2/GIN. THE ANALYSTS 5.

SUMMARY The oil/gas contact was picked at 10,660 feet due to the distinct increase in brilliant abundant oil fluorescence. The high gas influx into the hole before the mud weight was increased mad~ establishing a methane to heavy- hydrocarbon ratio~.~ impossible. Connection gases were high and made exact determination Of formation gas at the bit questionable. The IDEL Program (Instantaneous Drilling Evaluation Log) was able to clearly distinguish the sand from the shale sequences and successfully recognized a shale-sand sequence at the base of the Sadlerochit. Its ratty nature and thin shale lenses made detection with the Teleco Gamma Tool difficult. The fact that these lenses were being penetrated at such a severe angle could account for the difficulty in detecting the lenses with a Gamma Ray tool. The sands immediately above and below the shales seemed to overshadow the density of the shales with their porosity.

Describe Proposed or Completed Operations (Clearly state all pertinent details and give pertinent dates, including estimated date of starting any proposed work, for Abandonment see 20 AAC 25.105-170). ARCO Alaska, Inc., proposes to change the casing program on DS 15-8. On the original, approved casing program, approximately 640' of 7", 32#, L-80, BTC slotted liner (.058") was to be run, uncemented, in the lower most portion of the Sadlerochit below the standard 7" liner. The new casing program would have the same 7", 29#, L-80, BTC liner (cemented) from 11,186'MD (8800'TVD) to 300' inside 9-5/8" casing, but the uncemented slotted liner would now be 5", 18#, S-95, LTC liner with .058" slots. This would be run from 11,925'MD (8928'TVD) to 100'+ inside the 7" liner (approx. 740' total length). Also, because the final hole angle will be 80°±, it is doubtful that a continuous gyro survey can be run to TD. Therefore, ARCO Alaska, Inc., proposes to run a multishot survey on drillpipe in the 8-1/2" hole from . 11,925'MD (8928~'TVD) to 9847'MD (8406'TVD). This will be tied into the gyro which will be run past 9847'MD until it stops. Estimated Start: SePtember 12, 1984 RECEIVED SEPO 51 4, AlasKa Oil & Gas Cons. Commission Anchorage 14.

Dear Mr. Fithian: Enclosed is the approved application for permit to drill the above referenced well. Approval of this application for permit to drill DS 15-8 DOES NOT approve the running of 7", 32~/ft, L-80, BTC casing with 0.058" slots cut in the pipe body. Approval of your request to run an -~ncemented slotted liner in'this well is dependent upon the issuance of a conservation order exempting ARCO Alaska, Inc. from the requirements of Rule 3 of Conservation Order No. 145. A notice of this request will be published on September 2, 1984, and a possible hearing date is set for 9:00 ~ on September 14, 1984, after which an order may be issued. In the event a conservation order cannot be issued, conventional cemented 7", 29~/ft, L-80, BTC casing must be run in place of the slotted liner. If coring is conducted, a one cubic inch chip from each foot of recovered core is required. Samples of l~ we~, cuttings and a mud log are not required. A continuous directional survey is required as'per 20 AAC 25.050(b)(5). If available, a tape conta~nzng the digitized log information shall be submitted on all logs for copying except experimental logs, velocity surveys and dipmeter surveys. Many rivers in Alaska and their drainage ~ystems have been classified as important for the spawning or migration of anadromous fish. Operations in the~e areas are subject to AS 16.05.870 and the regulations promulgated thereunder (Title 5, _ . Hmo T. L. Fithian P~adhoe Bay Unit DS 15-8 August 31, 198& Alaska Administrative Code). Prior. to commencing operations ~ou~ may be contacted by the Habitat Coordinator's Office, Department of Fish and Game. Pollution of any waters of the State is prohibited by AS 46, Chapter 3, Article 7 mhd the regulations promulgated thereunder (Title 18, Alaska Administrative Code, Chapter 70) and by the Federal Water Pollution Control Act, as amended. Prior to conmaencing operations you may be contacted by a representative of the Department of Environmental Conservation. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Where a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe. In the event of suspension or abandonment, please give this office adequate advance notification so that we may have a witness present. Ve~ trul, ~yours, C. V.

Logs will be run across selected intervals. A 13-5/8", 5000#, RSRRA BOP stack will be installed and tested. The annular preventer will be tested to 3000 psi and rams tested to 5000 psi. The BOP equipment will be pressure tested each week and operationally tested each trip. A string of 4-1/2", 12.6#, L-80 tubing and packer will be run. Provisions for subsurface safety equipment will be run. The packer will be set above the Sadlerochit. A non-freezing fluid will be left in all uncemented annuli within the permafrost interval: A surface diverter will be installed and operationally tested prior to spud. DS 15-8 will be 120' from DS 15-7 at the surface. There are no other wellbores closer than 200' anywhere along the proposed well course. Reserve pit fluids will be disposed of down the 9-5/8" x 13-3/8" annulus of this well.

The slotted liner will be 7", 32#/ft, L-80, BTC casing with 0.058" slots cut in the pipe body and will be run only across the Zone 1 portion, approximately the lower_6~4Q'~ of the liner string. The remainder of the liner will be conventional 7", 29#/ft, L-80, BTC casing from the top of the slotted to the liner hanger. An external casing packer (ECP) will be run between the conventional and slotted liner. Class "G" cement will be circulated through a stage collar above the ECP to the top of the liner. Realizing that running an uncemented portion of the production liner across the Sadlerochit violates existing Field Rules, ARCO Alaska, Inc., requests an exception to Rule 3 (f) of Conservation Order No. 145 and the Prudhoe Bay Field Rules. The use of an uneemented slotted liner completion technique should allow increased production in Prudhoe Bay upstructure wells. aOe ~rni$~io~ ,.,', ;;~ ,.~;~, ~ ii;~' ' ,~,~' ~'~,~ .... ] - ~ ' ' ..t,.~hf~h ~1. :~h,t,hl~!f~,t~l~hllti,t~,Iilht~,,[l~,![t~,i[!l!t~lltti[l,!
