The pennit 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 pennitting determinations are made. The pennit is for a new wellbore segment of existing well PBU A-38, Pennit No 193-032, API 50-029-22347. Production should continue to be reported as a function of the original API number. stated above. '. . Annular disposal has not been requested as part of the Pennit to Drill application for Prudhoe Bay Unit A-38L. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Attachments Date y \ (~ .(),:~ Submi~ In Triplicate ) ) BP A-38L 1 CTD Sidetrack Summary of Operations: / A CTD through tubing sidetrack is planned for A-38. The coil sidetrack, A-38L 1, will exit the 5 1/2" liner in the Sag R. formation and target Zone 4. A-38L 1 will be completed with a slotted liner therefore both the Sag River and Zone 4 will be open for production from the new sidetrack. The existing A-38 perfs in Zone 4 will be open to produce through the standing valve and the flow-through whipstock. One fault splay, 10-15 ft throw, will be crossed. This fault orientation and throw suggest a minimal risk of lost circulation. A-38L 1 will be completed with a slotted liner to enable continued production from the existing Zone 4 perfs. If lost circulation or high water saturation is encountered then a request will be filed with AOGCC to change -* the sidetrack completion to a cemented liner and simultaneously change the sidetrack name to A-38a. / Phase 1: Prep work. Planned for April 10-17, 2002. 1. E-line to set standing valve at 11,620'. 2. E-line to set flow-through whipstock at 11,530'. / Phase 2: Mill window, Drill and Complete sidetrack: Planned for April 28, 2002. Drilling coil will be used to mill the window then drill and complete the directional hole as per attached plan. Maximum hole angle will be 93 degrees. Mud Program: . Phase 1: Seawater . Phase 2: Mill with seawater/biozan, drill with Flo-Pro (8.6 - 8.7 ppg) Disposal: . All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. . All Class I wastes will go to Pad 3 for disposal. Casing Program: The production liner will be a 3 Y2" ST -L x 3 3/16" TC II x 2 7/8" solid/slotted liner from TD to approx. ./ 11 ,315'MD (8,597'ss). Only the top joint will be 3 Y2". Open hole will be 3.75". Liner will be un-cemented. Well Control: . BOP diagram is attached. /' . Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 3500 psi. . The annular preventer will be tested to 400 psi and 2500 psi. Directional . See attached directional plan. Max. planned hole angle is 93 deg. . Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging . MWD Gamma Ray & Resistivity logs will be run over all of the open hole section. . / A Pad is an H2S pad. The maximum recorded H2S is 200 ppm on well A-43. The existing completion, A-38, has been fraced. Losses may occur if the sidetrack encounters the frac wing. One small fault splay offers some risk of lost circulation. Losses or high water saturation may result in abandonment of the sidetrack or a change to a cemented completion. Hazards . . . ') ) Reservoir Pressure Res. press. is estimated to be 3460 psi at 8800'ss (7.6 ppg emw). Max. surface pressure with gas (0.12 psi/ft) to surface is 2404 psi. ./ TREE = 4-1/16" 5M CrN WELLHEAD= FMC 'k:'ëTüATÖR;^,~""""m,^",,^,w^'õTls "Krr"ErBr;""'"'.""'-''''''''''ãM~i':45'i. SF: ïiE\i;.
