Marathon Oil Company submitted applications dated Apri123, 1998 and Apri124, 1998 requesting exception to the well spacing provisions of 20 AAC 25.055(a)(4). The first exception would allow drilling the Sterling Unit 41-15 gas development well to a producing location closer than 1500 feet to a section line in an undefined gas pool. The second would allow drilling the Sterling Unit 32-9 gas development well to a producing location that is closer than 3000 feet from another well capable of producing from the same pool. 2. The Commission published notice of opportunity for public hearing in the Anchorage Daily News on May 2, 1998 pursuant to 20 AAC 25.540. 3. No protests to the application were received. FINDINGS: The Sterling Unit 41-15 gas development well will be drilled as a deviated hole from a surface location of 2327' from the south line (FSL) and 437' from the east line (FEL) of Section 9, TSN, R10W, Seward Meridian (SM) to a bottomhole location 4208' FSL and 1049' FEL of Section 15, TSN, R10W, SM. The Sterling Unit 32-9 gas development well will be drilled as a deviated hole from a surface location of 2312' FSL and 449' FEL of Section 9, TSN, R10W, SM to a producing location of 2706' FSL and 2197' FEL of Section 9, TSN, R10W, SM. 2. Offset owners Bureau of Land Mangement, U.S. Minerals Management Service, Cook Inlet Region, Inc and the State of Alaska have been duly notified. 3. An exception to the well spacing provisions of 20 AAC 25.055 (a)(4) is necessary to allow the drilling of these wells. Conservation Order No. 42~ May 20, 1998 Page 2 CONCLUSION: Granting a spacing exception to allow drilling of the Sterling Unit 41-15 and the Sterling Unit 32-9 gas wells will not result in waste nor jeopardize correlative rights. NOW, THEREFORE, IT IS ORDERED: Marathon Oil Company's applications for exception to the well spacing provisions of 20 AAC 25.055 (a)(4) for the purpose of drilling the Sterling Unit 41-15 and the Sterling Unit 32-9 gas wells are approved. DONE at Anchorage, Alaska and dated May 20, 1998. ~~.~ ~° '~ ti ,{ ~ F] ~ 1 ~ ~~ p$ j - -^'..~~ tea. ~ .~ ~~`~®t+~ ~~({/ ~I Cammy Oechs Commissioner Alaska Oil and as Conservation Commission AS 31.05.080 provides that within 20 days after receipt of written notice of the entry of an order, a person affected by it may file with the Commission an application for reheazing. A request for rehearing must be received by 4:30 PM on the 23`d day following the date of the order, or next working day if a holiday or weekend, to be timely filed. The Commission shall grant or refuse the application in whole or in part within 10 days. The Commission can refuse an application by not acting on it within the 10-day period. An affected person has 30 days from the date the Commission refuses the application or mails (or otherwise distributes) an order upon reheazing, both being the final order of the Commission, to appeal the decision to Superior Court. Where a request for reheazing is denied by nonaction of the Commission, the 30-day period for appeal to Superior Court runs from the date on which the request is deemed denied (i.e., l0u' day after the application for reheazing was filed). Alaska Oil and Gas Conservation Commission ~3 Notice of Public Hearing STATE OF ALASKA Alaska Oil and Gas Conservation Commission Re: The Sterling Unit 32-9 and Sterling Unit 41-15 gas development wells. Marathon Oil Company by letters dated Apri123, 1998 and April 24, 1998 has requested two exceptions to the spacing provisions of 20 AAC 25.055(a)(4) for the drilling of two development gas wells within the Sterling Unit, east of the city of Kenai. The first exception would allow Marathon to drill the Sterling Unit 41-15 gas development well to a producing location closer than 1500 feet to a section line in an undefined gas pool. The well will be drilled as a deviated hole from a surface location of 2327 from the south line (FSL) and 437' from the east line (FEL) of Section 9, TSN, R10W, Seward Meridian (SM) to a bottomhole location 4208' FSL and 1049' FEL of Section 15, TSN, R10W, SM. The second exception would allow Marathon to drill the Sterling Unit 32-9 gas development well to a producing location that is closer than 3000 feet to another well capable of producing from the same pool. The well will be drilled as a deviated hole from a surface location of 2312' from the south line (FSL) and 449' from the east line (FEL) of Section 9, TSN, R10W, Seward Meridian (SM) to a producing location of 2706' FSL and 2197' FEL of Section 9, TSN, R10W, SM. A person who may be harmed if the requested order is issued may file a written protest prior to 4:00 PM May 18, 1998 with the Alaska Oil and Gas Conservation Commission, 3001 Porcupine Drive, Anchorage, Alaska 99501, and request a hearing on the matter. If the protest is timely filed and raises a substantial and material issue crucial to the Commission's determination, a hearing on the matter will be held at the above address at 9:00 AM on June 2, 1998 in conformance with 20 AAC 25.540. If a hearing is to be held, interested parties may confirm this by calling the Commission's office, (907) 279-1433 after May 18, 1998. If no protest is filed, the Commission will consider the issuance of the order without a hearing. If you are a person with a disability who may need a special modification in order to comment or to attend the public hearing, please contact Diana Fleck at 279-1433 no later than May 27, 1998.

Marathon's current plan is to convert the SU 43-9 to a water disposal well after successful completion of SU 32-9, as the new well is anticipated to be ~50 feet updip and allow gas production without water coning.
