There were no protests to the application. FINDINGS: · · 20 AAC. 25.035(b)(1) is as follows: (b) Surface Hole Diverter System: (1) before drilling below the conductor string, at least one remotely controlled annular pre- venter and flow diverter system must be installed; the annular preventer must permit the diversion of hydro- carbons and other fluids; the low pressure, high capac- ity diverter system must provide at least the equiva- lent of a six-inch line with at least two lines venting in different directions to insure safe downwind diver- sion and must be designed to avoid freezeup; these lines must be equipped with full-opening butterfly type valves or other valves approved by the Commission; a schematic diagram, list of equipment, and operational procedure for the diverter system must be submitted for approval with the application for a Permit to Drill (Form 10-401); and The drilling rig on the referenced well site will have a diverter system that vents gas in the derrick at the derrickman's position. Conservation Order No. 177 Page 2 o · The diverter system as proposed has functioned safely for more than 10 years on rigs on platforms in Cook Inlet. An exception, as requested, to 20 AAC 25.035(b)(1) for the rig on the referenced well will not create an unsafe drilling practice. NOW, THEREFORE, it is ordered that: The drilling rig to be used on the No Name Island No. 1 well is exempted from the specific requirements of 20 AAC 25.035(b)(1) which require the equivalent of a six-inch line with at least two lines venting in different directions. A system with a minimum six-inch diverter flowline to a degasser and vented by a minimum six-inch line at the derrickman's position or the crown is approved.

Hamilton, Commissioner Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501 Dear Sir' Revised Drilling Permit No Name Island Well No. 1 (Formerly Narwhal Well No. 1) ADL 312814 Attached in triplicate is a revised Permit to Drill (Form lO-401) for the Beaufort Sea exploratory well, No Name Island Well No. 1. Our original permit for this location referred to the well as "Cross Island Well No. 1" (please see letter and permit dated March 5, 1980, File' LAD-202-WF). We later decided to change the well's name to "Narwhal Well No. 1" and proposed this in a letter and Form 10-403, Sundry Notices and Reports on Wells, dated March 13, 1980, File' LAD-277-WF. On July 22, 1980, we received the approved Forms 10-401 and 10-403 from your office. Our company later decided not to drill this well as planned in the 1980 winter drilling season, with spud on November l, 1980. According to your Regulation 20 AAC 25.005, Section K states' "If drilling is not commenced within. 24 months after the approval date, the drilli'ng permit will expire." Thus, we assume our permit for Narwhal Well No. 1 is still in effect, noting the July 11, 1980 approval date. AUG - Dil & G~s Cons. Commission Ao. chorag.~ July 31, 1981 LAD-838-WF Page 2 With this in mind, please consider the enclosed Form lO-401 as a proposal for a name change from Narwhal Well No. 1 to No Name Island Well No. 1, although we have not changed islands. The surface location has been · accurately established due to the recent drilling pad construction and conductor pipe installation. The bottomhole location has also been updated due to the most recent geologic interpretation of the Kekiktuk Formation. Finally, the revised casing and cement programs enclosed are designed to accommodate an annular injection program of waste fluids, an operation not considered in previous casing designs. No Name Island Well No. 1 is to be drilled from a surface location on No Name Island 2471' FWL, 605' FSL, Section 23, T13N, R16E, Umiat Meridian. The primary downhole objective is the Kekiktuk Formation at 100' FWL, 1525' FSL, Section 26, T13N, R16E, Umiat Meridian at an estimated depth .of 10,352' subsea. Attached to the permit are several maps locating the island and surface and bottomhole locations, a surveyor's plat showing the surface location, and a detailed casing and cementing program. Diagrams of our BOP equipment have been included also, and we plan to run our surface hole diverter line in the derrick of the rig to allow safe diversion of any surface gases encountered. We feel this is the safest means of gas diversion for this island operation, and therefore request an exception to the Commission's surface hole diverter regulation (.20 AAC 25.035, Section B) requiring two.diverter lines be laid horizon- tally in two different directions. Please refer to your letter dated June 4, 1981, and our previous request for a blanket exception for our Cook Inlet platforms dated July 7, 1981, File: LAD-754-447.1. We are providi.ng .this application for your review and immediate approval. Please advise us if you have any questions. As this is an exploratory well, we request that all reports and information filed with the Commission regarding it be kept confidential. Yours very truly; L. A.

Smith Commi s s i oner Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501 Dear Sir' Request for Exception Surface Hole' Diverter Ssstem With regard to your recent requesi~ for comments involving the Surface Hole Diverter System Regulation (refer to your letter dated June 4, 1981, Regulation 20 AAC 25.035, Section B), Amoco is requesting an exception to the section of this regulation which states' "...the low pressure, high capacity diverter system must provide at least the equivalent of a six-inch line with at least two lines venting in different directions to insure safe 'downwind diversion..." We request this exception for all four of our Cook Inlet platforms for all present and future drilli.ng operations. Our present system of diversion, as seen in Attachment I, vents gas in the derrick above the rig floor at the crown on platforms Anna 'and Dillon, and at the derrickman's position on Bruce and Baker. Historically, this system has been rarely, yet successfully utilized to divert small amounts of coal gas while drilling at these shallow depths. This gas is low volume and 'tends to deplete quickly. This system has also been inspected by your personnel in the recent paSt and was found to be~'~ satisfactory. -/U/. LAD-754-447.1 July ~, 1981 ?age Furthermore, it is felt that diverter lines laid horizontally for diversion of flow in two directions on an offhsore platform is far more hazardous than our present system since there are many potential ignition sources at or near the deck level that could easily ignite vented gas in the event of a sudden wind change or similar occurrence. Also, our system is functionally identical to the system seen in the API Recommended Practices for Blowout Prevention Equipment Systems Bulletin (API RP 53), Page 4, Figure 2.A.1; the API recommendations bei.ng widely accepted as the standard of the industry. In closi.ng, we will appreciate your consideration of our request for this exception and will be glad to field any questions or comments you may have r. egarding this regulation and our system. We.also invite you or any of your associates to visit our platforms and inspect the diverter systems at your convenience. Very truly yours, ., L. A.
