The pennit to drill does not exempt you from obtaining additional pennits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required pennitting detenninations are made. The pennit is for a new wellbore segment of existing well Prudhoe Bay Unit X-35, Pennit No. 193- 199, API 50-029-22436. Production should continue to be reported as a function of the original API number stated above. 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.

We have now drilled the permitted plan and logging suggest that the oil in our primary target has been effectively swept. Rather than stopping, we would like to drill onto another banked oil target some 550' further on. Prep work, (Phase 1) and drilling, (Phase 2) operations are detailed below. Phase 1: Screen & Prep Well: Screen - Install dummy GlV's, fluid pack IA & MIT. Fluid pack OA & MIT. Pressure test wellhead seals & tree valves. Completed May 1ih, 02 . E-Line set permanent isolation packer with modified check vlv at 14,050'md, (8945'tvd) Rig-Coil set mechanical thru-tbg, flo-by whipstock at 13,970' md, (-8,883' tvd). . Note: a 10-403 Sundry Permit was not submitted as the existing production intervals are being retained Phase 2: Drill and Complete CTD sidetrack: Started May 18th, 02. 2%" coil has drilled -1480ft of 3%" OH sidetrack from a window cut in the 5%", 13Cr liner at 13,970'. This is already 320' beyond planned TO. As per the attached plan the well will be extended a further 260' to 15,713', with the aid of jointed pipe, added to the BHA. This will bring the additional footage above 500ft, (583' to be exact). The original completion plan remains, that is uncemented 33/16" solid & 2~ slotted liner. Mud Program: . Phase 1: Seawater . Phase 2: Seawater and Flo-Pro (8.6 - 8.7 ppg) Disposal: . No annular injection 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: . 33/16" l-80 solid liner run from 13,750'md (TOl, 8,692' tvd) to 100' outside of the window at 14,075' md . 2~" l-80 solid & slotted liner from 14,075' to TO at approx. 15,710' md - solid joints will be run from T8AO back to the liner deployment sleeve. Well Control: . BOP diagram for Nabors 3S rig 1 Schlumberger CT Unit 4 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 . Real time MWO, Gamma Ray will be run in the open hole section. Memory Resistivity may be logged after reaching TO Hazards . X-35 was last tested for H2S on the 3/11/02, and reco.rd~d a 20ppm sample concentration. . No fault to be crosses prior to TO has a low lost circulation risk. Reservoir Pressure Reservoir pressure is estimated to be 3,325 psi at 8,800ss. Maximum surface pressure with gas (0.12 psi/ft) to surface is 2,269 psi. ......

".- Well Control: . BOP diagram for Nabors 38 rig / Schlumberger CT Unit 4 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 . Real time MWD, Gamma Ray & Resistivity logs will be run in the open hole section. Hazards . X-35 was last tested for H2S on the 3/11/02, and recorded a 20ppm sample concentration. . No faults are prognosed along the planned wellbore, however there is a risk of loosing circulation to open Z4B perfs above the whipstock. In this event conventional lCM will be used to manage fluid loss. Reservoir Pressure Reservoir pressure is estimated.to be 3,325 psi at 8,800ss. Maximum surface pressure with gas (0.12 psi/ft) to surface is 2,269 psi. ./ X-35 ) I SAFElY I\UTES: 13 CI-ROWE OO~LETION TREE = 4"5MCAMERON W8.LHEAD = 11" 5M FMC A CTljt\ TOR = BAKER KB.
