The following summarizes the procedure required to prep 5-23 for drilling and is submitted as an attachment to Form 10-403. A schematic diagram of this proposed completion is attached. ]. Tree wing & master valves will be tested. 2. Using slickline, the tubing will be drifted and the gas lift mandrels will be dummied off. 3. Inner Annulus will be liquid packed and pressure tested. 4. Service coil will abandon the current perforations (9212'-9228' MD) with 17 ppg cement. The cement plug will extend approximately 100 feet above the proposed KOP, which will be at approximately 8982'MD (8,598' TVDss). 5. Service coil may then mill a 2.8" window out of the 5 1/2" liner. Slickline, wireline & service coil prep work is expected to commence September 26, 2001. Coil tubing drilling operations, as detailed below will commence October 2, 2001. ]. A 3" sidetrack, -700' long will be drilled out of the 5 1/2" liner, high side into the Zone 1 reservoir. 2. The sidetrack will be completed with a 2-3/8", solid, cemented & perforated liner. M.S.

Johnston, Chairman Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, AK 99501-3192 RE: Drillsite 5-23 Dear Commissioner Johnston: ARCO Alaska, Inc. has reviewed the Commission's June 15, 1994 order which levies a $5,586 penalty under the authority of AS 31.05.150(e) and a $35,000 penalty under the authority of AS 31.05.150(a). ARCO Alaska, Inc. will not appeal the Commission's order imposing these penalties. Enclosed please find ARCO's check in the amount of $40,586 in payment of these penalties. ARCO's payment of these penalties is not an admission that its actions were negligent. However, this incident demonstrated that ARCO's wellhead safety procedures could be improved. Consequently, as previously discussed, ARCO has revised its procedures to prevent this type of incident in the future. The Commission's recent revisions to Rule 5 of Conservation Order 145 will also serve to prevent a reoccurrence of this type of incident. Very truly your~~~ Le~ona~rd C.~~Gur~'ul~/H.

HICKEL, GOVERNOR 3001 PORCUPINE DRIVE ANCHORAGE, ALASKA 99501-3192 PHONE: (907) 279.1433 TELECOPY: (907) 276-7542 John Whitehead ARCO Alaska, Inc. P.O. Box 100360 Anchorage, Alaska 99510-0360 Re: Drill Site 5-23 Oil Spill Dear Mr. Whitehead: The Commission is reviewing the Drill Site 5-23 oil spill on December 30, 1993 for possible imposition of penalties under AS 31.05.150. The spill occurred when high winds caused failure of the 5-23 flow line. Spill size was approximately 365 to 400 barrels of crude oil and 4.0 and 5.3 MMSCF of gas. The Commission concludes the initial cause of the spill was force majeure. ARCO Alaska, Inc., however, appears to have aggravated the spill because it shut-in the well at the well house and disabled the well's safety valve system. ARCO's failure to secure the well at the well head appears inconsistent with sound engineering practices and may violate 20 AAC 25.526, as well as its own operating procedures. Disabling the safety valve system is a violation of Commission regulations, 20 AAC 25.265. Both actions appear negligent. Further, ARCO may have engaged in these actions knowing that each was a violation of Commission regulations. The Commission may impose a civil penalty of $5000.00 per day on persons who negligently violate the statutes and regulations of the Commission. AS 31.05.150(a). It is also within the power of the Commission to define all vented gas related to this incident as waste under AS 31.05.170. Should the Commission conclude, based on the evidence presented, that either a willful or negligent act(s) by ARCO or its employee contributed to the incident, then a penalty may be assessed on every 1000 cubic feet of natural gas vented or otherwise determined to be waste. The penalty is based upon the fair market value of natural gas at the point of waste. AS 31.05.170(e). Before the Commission makes a determination concerning possible imposition of penalties, we are providing you, or anyone else, with an opportunity to provide any additional information to show whether or not the incident was the result of a willful or negligent act(s) and if the gas vented as a result of the incident should be considered waste. Any information you would like to have us consider must be presented in writing or in person before 4:30 PM on April 8, 1994. This will be your final opportunity to comment before we render a decision in tkis matter. Although penalties are being considered, the Commission wants to compliment you and the rest of the ARCO incident staff for their handling of this case and their forthrightness in reporting the incident to the Commission. The Commission notes that ARCO's response and follow-up to this incident has been reasonable and responsible. We believe ARCO thoroughly investigated the incident and reported all its findings and conclusions to the Commission. We believe the action plan adopted by ARCO, if enforced, will help prevent a similar incident in the future. David W. Chairman cc. Rob Mintz, Dept. of Law ARCO Alaska, Inc.

At approximately 8:30 am on January 5, 1994, ARCO contacted the AOGCC to request regulatory guidance regarding the handling of contaminated snow generated from the cleanup of the spill from the DS 5 Well 23 flowline separation that occurred on December 30, 1993. ARCO proposed to place the contaminated snow removed from the DS 5 reserve pit and from the adjacent tundra into the lined pit at Pad 10 that is used for the annual reserve pit dewatering efforts. After placement into the pit, the snow would be solidified with water to ensure that any future winds will not remove this material from the pit. The material would be left in place until "thaw" on the North Slope and would then be injected into the FS 1 Class II disposal well located near the Pad 10 pit. It should be noted that the crude oil recovered from this spill that was suitable for recycling into the production process has been (or is in the process of being) recycled. The material proposed for placement into the Pad 10 pit is material that is unsuitable for recycling due to the high water (i.e. snow) content. The AOGCC stated that they would review our request and would advise ARCO of its position on this proposal. At approximately 11:50 am on January 5, 1994, the AOGCC contacted ARCO and provided verbal approval for ARCO to proceed with our proposal, as outlined above. ARCO would like to thank the AOGCC for its prompt consideration of and response to our request for regulatory guidance on this matter.

While inspecting the welded area that ruptured I noticed that the weld appeared to have failed where the two pieces of pipe came together upstream of a double offset. I also noted that the cap weld seemed to be on one piece of pipe. Both of these items do not seem to be consistent with good welding practices, normally the welded area will fail in the parent metal in the proximity of the weld. In the past I have had experience with welding and feel confident in my inspection. The double offset area required 4 welds to complete, the other welds seemed to demonstrate good integrity. ARCO is doing further metallurgical tests on the failed weld as well as the other welds in the double offset, these tests will be available at a later date.

They gave me the following information about the ongoing clean up efforts: · Estimated amount of Oil contained 95% (All but the mist carried by the wind contained). · Total volume of fluid recovered to date 3,445 BBL (Melted Snow), 328 BBL Oil. · Total volume of solids 3,235 Cu/yds of snow stock piled, 22.5 Cu/yds gravel transported to Oily Waster Disposal Pad 3.- · Surveyed Contaminated Area 101 Acres. · No injuries. The rupture flow line section had been removed prior to my arrival, the ruptured section was approximately 3 ft. in length and located half way between the VSM's. This section consisted of a 45° turn and a straight run connected to another 45° turn. The second 45° turn was in place and unharmed. I viewed the contaminated area in the reserve pit and surrounding area and with the exception of the oil visible on the road signs, flowlines, and immediate pad area it is difficult to distinguish the dust and gravel blown off of the road system from the oil mist. A trench approximately 5 ft. deep was opened up in the reserve pit to allow the placement of a snow melting unit in close proximity to the major spill area. The walls of the trench gave an excellent cross sectional view of the major spill area. This visible cross section showed approximately 1/4" of oil on the surface and clean snow all the way to the frozen bottom of the reserve pit. The major volume of the oil spill was contained in a small dike area directly under the ruptured flow line inside the reserve pit. All contaminated areas have been roped off and signs installed designating these areas as Hot Zones. The majority of the clean up effort has been and is still being hampered by high winds and subzero temperatures. Prior to 1/2/94, all snow removal was accomplished by shovel and a small 1/2 yard Front End Loader. The Eastern side of the drill site is being utilized as the staging area for the spill recovery and decontamination modules as well as the sampling station for all Vac Trucks used to recover and transport the contaminated snow to Flow Station 1 or Pad 3, ' Summary: I inspected the ruptured flow line and Oil Spill area at Arco's PBU DS5-23. · Attachment DS5 Incident Map.

Supervisor FROM: John Spauiding c~74.~¥~ Petroleum Inspec{o{" STATE Ol ALASKA ALASKA OIL AND GAS CONSER VA TION COMMISSION DA TE: December 31, 1993 FILE NO: ge9114ad. DOC PHONE NO.: 279-1433 SUBJECT: Line Rupture / Oil Spill ARCO PBU DS 5 Well 23 Prudhoe Oil Pool FridavDecember 31.1993: ! traveled this date to ARCO's drill site 5 well 23 to investigate and inspect the 6" flowline rupture and resultant oil spill. ARCO has reported the spill to be between 300 and 400 barrels crude oil. The break occurred in a 6" flow line from well 23 to the drill site 5 manifold building. The break and spill occurred at the upstream weld on a double offset approximately 1/4 mile from well 23's wellhead. The winds at the time of the leak and rupture of the line ranged from 58mph on the surface to 71 + mph 50' above surface, these figures were obtained from ARCO's weather and flight tower. " This well has a high gas oil ratio and was being operated as a cycle well, being shut in periodically. Well 5-23 was shut in from its last cycle date on 12-24 93. The shut in and flowing periods are determined by ARCO's reservoir engineering group. The inlet gate. valve IGV was shut at the manifold building and no valves were closed on the wellhead. Rich Helinski ARCO Spill Response Team/[Supervisor / Coordinator informed me that he received a call of the spill at DS 5 at 7:57 am 12/30/93 and he was on location at approximatelY 8:07 am 12/30/93. Well 5-23's automated SVS was manually activated at 7:40 am. Mr. Helinski noticed that well 23's flowline was jumping 1' to 2' off the vertical support members evidently from the strong winds. ARCO's S.R.T. response to this incident was excellent and showed that good planning and training has paid off. The pressure sensitive S.V.S. had been disabled and ARCO at this time is conducting an internal investigation to determine the reason why. Leonard Gurule ARCO PBU Operations Manager confirmed the above and told me that information would be made available as soon as there investigation was complete. The bulk of the oil seems to be contained in the reserve pit, with a light misting covering an area of approximately 101 acres. The light misting occured over an area about 200' wide by almost a mile long due to the high winds. Attachment DEC ?~--.' 9~ h ....

Grimaldi Petroleum Inspector Wednesday 12/5/90: i witnessed a diverter test on Doyon 9 drilling rig fo~-'~RC0'°~-J~rillsite 5, well #20, Prudhoe Bay Unit. I found the outlet of the diverter lines to be too close to the rig. I informed company rep. Dan Jackson and he had more 10" line brought in to extend them to the proper length. I also found the HCR valves coming from the side of the spool were not sequenced. I called Lonnie C. Smith and obtained a verbal variance to that effect. Other than the aforementioned, I found no other problems. 02-00lA (Rev. 6/89) 20/11/MEMOl.PM3 TO: THRU: MEMOR I Uo Stale of Alaska GAS VATION COMMISSION Lonnie C.

Excess non-hazardous fluids developed from well operations and as necessary to control fluid level in reserve pit will be pumped down the 7-5/8" x 10-3/4" annulus. The annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sx of cement followed by Arctic Pack. b. Wells within 200' of the proposed well are: DS 5-16 89' DS 5-15 97' DS 5-17 107' @ 3700' TVD / MD @ 4000' TVD / MD @ SUFACE TO 2500' TVD / MD Ce The drilling fluid program and fluid surface system will conform to the regulations set forth in 20AAC25.033. d. Maximum surface pressure is based upon BHP and a full column of gas to TD (0.10 psi / ft). e. Based upon previous logs on DS 5, no potential productive zones are anticipated above 4000' TVD. f. No potential hazardous levels of H2S are anticipated in this well.
