PO Box 196612 Anchorage AK 99519 Re: Cancelled or Expired PTD's. Dear Gunkel: September 6, 2001 The Alaska Oil and Gas Conservation Commission ("AOGCC") approved the following referenced permit to drills. The AOGCC has a long-standing policy of releasing cancelled or expired permits two years from the date the application was approved by the AOGCC. The following files are scheduled to be released October 1,2001. Permit to Drill No.'s: -97-047 98-019 99-002 97-056 98-050 99-009 97-082 98-135 97-090 98-154 97-100 98-155 97-121 98-164 97-159 98-167 97-191 98-177 98-210 98-211 98-223 98-236 98-257 98-261 Sincerely, Memorandum State of Alaska Oil and Gas Conservation Comm~ Well File: C~c~ _ (~ ~a.~ DATE Re: Cancelled or Expired Permit Action EXAMPLE: Point Mclntyre P2-36AXX AP1 # 029-22801-95 3l, tqct This memo will remain at the from of the subject well fie. Our adopted conventions for assigning AP! numbers, permit numbers and well names did not specifically address expired or cancelled permits. This omission has caused some inconsistencies i' the treatment of these kinds of applications for permit to ddll. Operators have asked us to adopt formal procedures for this class of permit application in order to prevent future database disparities. If a permit expires or is cancelled by an operator, the permit number of the subject permit will remair. unchanged. The APl number and in some instances the well name reflect the number of preexistin,( reddils and or muitilaterais in a well. In order to prevent confusing a cancelled or expired permit ~ an active well or multilateral these case sensitive well identifiers will be changed for expired and cancelled applications for permits to ddil. The AP! number for this cancelled or expired permit is modified so the eleven and twelfth digits is 9[ The well name for a cancelled or expired permit is modified with an appended xx. These procedures are an addendum to the APl numbering methods described in AOGCC staff memorandum "Multi-lateral (weilbore segment) Drilling Permit Procedures, revised December 29, 1995. AOGCC database has been changed to reflect these changes to this permit. e MCMains ' ~ Statistical Technician ,.~hared BP Exploration / Arco Alaska Date: October 9, 1998 To: At'tn: From: Alaska Oil & Gas Conservation Commission Mr. Jack Hartz Carol Withey ~ j~~---" Technical As~i~It~t III Shared Servic'e~s Drilling Jack: Per our phone discussion on Monday, October 5, I have attached the revised permit for B1-25L2. The following is a recap of our conversation. B1-25, B1-25L1, and B1-25L2 originally permitted and approved by AOGCC is no longer a multi-lateral well. We plan a single penetration utilizing the B1-25L2 surface, productive interval and bottom hole location coordinates. Drilling operations have been modified accordingly and are attached. We anticipate no changes in the drilling fluid program. We have not begun drilling operations and plan to move to the site within the next 7 days. Additionally, you asked I make the following request: Please contact Michael Cook, the operational drilling engineer at 564-5390 or myself at 564-4114 if you have further questions.

Thc permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize condUcting drilling operations until all other required permitting determinations are made. The permit is for a new wellbore segment of existing well B 1-25, Permit No. 98-153, API 50-029-22906. Production should continue to be reported as a function of the original API number stated above. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. -. Chairman BY ORDER OF THE COMMISSION dlEenclosures cc: Department of Fish & Game.

Fluid Handling: All drilling and completion fluids will be processed through the onsite Grind and Inject facility and injected into disposal well B1-01. Annular Injection: No annular injection is planned at this time. DRILLING HAZARDS AND RISKS: Wellbore proximity comments are addressed under each MLOH section. Junk (auger tooth) was encountered in the B1-16 conductor - if junk is encountered, ensure all junk is fished prior to commencing drilling. Stuck pipe - UGNU sands, West Sak Sands - differential Coals - stringers throughout well, 4500' to Canning formations at 9500' tvd. Badami sands are overpressured - normally 12.2ppg mw required at TD. Pressure transition begins just above shallowest sand. Shallow sands typically pressured between normal and the 12.2 ppg required in lower sands. Maintain minimum mud weight and utilize latest techniques to manage lost circulation hazards in shallow sands (flow rates, tapered drill string). Weight up as wellbore pressures dictate, maintaining a 200 psi overbalance throughout. /,~.. B 1-25 Producer - Multi-lateral PERMIT Hazards of well control and stuck pipe are managed by setting 7" casing above shallowest sand, before penetrating the full overpressure. Hazard of lost circulation is managed by proper techniques to maintain Iow ECD - ECD of 13.5 ppg noted to be maximum allowable to prevent lost circulation. snarea ;ervtces Drttttng DrillQ ~le: linch = ~ Eastings .3~0 3600 4~0 44~ 4~00 1800- - 1800 4 1/2" Liner- 12532.~ MD, D ' To~I ~p~: 12532.~ ~.~~ fl [ II I I I I I 3~0 ~ ~00 ~00 4800 ~le: linch = ~ Eastings Referenoe I~ True No~h 7" Casing - 10461.22 MD, 90~.80 ~D · .
