The referenced Rule 3 requires production casing or liner to be landed through the completion zone and cement to cover and extend to at lease 500 feet above the hydrocarbon-bearing formations which are potentially productive. · ARCO Alaska, Inc. proposes to run a slotted liner through the lower most section of the Sadlerochit Formation with no cement behind the slotted liner. The regular seven inch liner above the slotted section will be cemented to at least 500 feet above the hydrocarbon-bearing zone. · Notice of the application was published in the Anchorage Times on July 2, 1984. 4. There were no protests to the application. FINDINGS: 1. · Completions using a slotted liner are common in many oil-producing areas. There already have been open hole completions and gravel-packed completions in the Sadlerochit Formation in the Prudhoe Bay Field. CONCLUSION: The requested exception will not create waste and will add to the knowledge of completion techniques for the Prudhoe Oil Pool. Conservation Order. No. 199 Page 2 July 13, 1984 NOW THEREFORE, IT IS ORDERED THAT: ARCO Alaska, Inc. is exempted from the requirements of Rule 3 of Conservation Order No. 145 and may complete the Prudhoe Bay Unit No. DS 15-17 well with an uncemented slotted liner in the lower-most section of the Sadlerochit Formation.

Notice is hereby given that ARCO Alaska, Inc. has requested the Alaska Oil and Gas Conservation Commission to issue an order to grant the use of a slotted liner in the completion of the Prudhoe Bay Unit No. DS 15-17 well. Rule 3(f) of Conservation Order No. 145 requires all hydrocarbon-bearing zones be covered by cement which is not practical when a slotted liner is used. In support of this request, ARCO Alaska, Inc. states that the use of a slotted liner will provide additional information on completion techniques in the Sadlerochit Formation and should result in increased production in low potential wells. Parties who may be aggrieved if the order is issued granting the referenced request are allowed 10 days from the date of this publication in which to file a protest, in writing, stating in detail the nature of their aggrievement and their request for a hearing. The place of filing is the Alaska Oil and Gas Conservation Commission, 3001 Porcupine Drive, Anchorage, Alaska 99501-3192. If such a protest is timely filed, a hearing on the matter will be held at the above address at 9:00 AM on July 13, 1984 at which time protestants and others may be heard. If no such protest is timely filed, the Commission will consider the issuance of the order without a hearing. Harry W.

Chatterton Commi s s i one r State of Alaska Alaska Oil & Gas Conservation Commission 3001 Porcupine Drive Anchorage, AK 99501 SUBJECT: DS 15-17 Well Dear Mr. Chatterton: ARCO Alaska, Inc., requests an exception to Rule 3(f) of Conservation Order No. 145 and Prudhoe Bay Field Rules to be able to complete the subject well using a slotted liner. The use of a slotted liner is proposed to provide additional information on completion techniques in the Sadlerochit formation. Such a completion technique should allow increased production in low potential wells. We have filed the application for Permit to Drill DS 15-17, the required $100 filing fee, and a Sundry Notice changing the completion to a slotted liner. Attachments to the application included a plat detailing the section and plan views of the proposed well course, a sketch and description of the BOP equipment, and a sketch of the surface hole diverter. We anticipate being ready to run this completion on July 18, 1984. Your earliest approval would be appreciated. Sincerely, T. L.

The prime objective of the revised development plan is to improve Zone 1 productivity enough to achieve an adequate, sustainable oil rate from a small interval as low in the formation as possible. This will provide maximum GOC standoff and increase the probability of completing.under a competent shale. ARCO proposes to evaluate several different drilling/completion techniques at Drill Site 15. The performance of these wells will be closely monitored for the next six to eight months. Based on these results, "conventional" Prudhoe Bay practices can be modified to optimize completions on upcoming wells at Drill Site 18 and in other upstructure areas. Further, we see this 6-8 Well program as a logical progression leading to the possible drilling of a horizontal hole in the near future. The six well program will provide critical completion experience and compar- ative results for use in the future. Specific areas to be evaluated are: 1, Productivity improvements in conventionally drilled and completed wells perforated with large casing guns, shot underbalanced or overbalanced through a salt pill. . Productivity improvements when drilling with a clean, saturated, sized-salt brine, then not allowing cement filtrate to contact the formation. Slotted liner will be run with combination solid liner multi-formation packers cemented above the open-hole area. 3, Productivity improvements due to Item (2) above, used in a high angle well (i.e. 80° through Zone 1). 4. High angle hole drilling, logging, and completion performance: A, B, m~ Drilling tools, downhole assembly performance and angle control at 80°+ degrees deviation. Cementing competency. Sand/shale correlations, timely base of sand detection, and log interpretation techniques. MWD and GR capabilities.
