The permit to redrill 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. Annular disposal has not been requested as part of the Permit to Drill application for Prudhoe Bay Unit B-28A. Blowout prevention equipment (BOPE) must be tested in accordance with. 20 AAC 25 035. 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.

Summary of Operations: A CTD horizontal sidetrack of well B-28A is proposed. Specific prep work, (Phase 1) and drilling, (Phase 2) operations are detailed below. Phase 1: Isolate & integrity test inner annulus (IA). Drift liner. Set whipstock. P&A. Planned for January 7, 2002 . Integrity test IA after fluid packing & installing dummy gas lift valves. . Drift well with dummy whipstock to pbtd. . Set mechanical whipstock at 10,525'. . P&A existing perforations with approx.15 bbls of 17ppg cement. . Mill window with service coil if available. Phase 2: Drill and Complete CTD horizontal Sidetrack: Planned January 25, 2002 2 3/8" coil will be used to drill a 33A" open hole sidetrack, approx. 1320' feet. (as per attached plan) A solid/cemented and perforated 3-3/16" x 2-7/8" liner completion will be run. Max. hole angle will be 93 deg. Mud Program: . Phase 1: Seawater . Phase 2: Seawater and Flo-Pro (8.6 - 8.7 ppg) Disposal: . No annular disposal on this well. ,..-/'.. . 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: . 3 3/16" solid liner 6.2 #/ft run from the top of the liner at approx. 10,180'md to approx 10,585' md. Then crossed over to 2Ys" solid 6.16 #/ft liner which will be run to TO at approx 11 ,845'md. The liner will be cemented with approx. 19 bbls of 17 ppg cement. Well Control: . BOP diagram is attached. . Pipe rams, blind rams and the CT pack off will be pressure tested to 300 psi and to 3,500 psi. . The annular preventer will be tested to 400 psi and 2,200 psi. Directional . See attached directional plan. . Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging . An MWD Gamma Ray will be run over the open hole section. . Memory CNL will be run in the cased hole after reaching TO. Hazards . H2S was measured at 6 ppm on Dec 8, 1998. . One fault crossing is prognosed,. Reservoir Pressure . Reservoir pressure is estimated to be 3,300 psi (7.2ppg) ,at 8,800ss. Maximum surface pressure with gas (0.12 psi/ft) to surface is 2,244 psi. .,/' TREE = 4" Cr-N WELLHEA 0= FMC AêffiJATOk;"'" """""^"6rìS '..,......,....,......,..",.,..,...,........... """"""""... KB.
