The sidetrack, NK-62A, will kick off from a window milled in the DFS sand and will target tl~B~B~and. All existing perfs will be cement squeezed and the new sidetrack will be completed with a fully c~t~ted liner. -'~' The following describes work planned to prep for sidetracking and is submitted as an attachment to Form 10- 403. A schematic diagram of the proposed sidetrack is attached for reference. 1. Install dummy gas lift valves. Drift and tag TD. 2. MIT tubing, IA, OA./' 3. Run caliper log in 7" liner and in 4-1/2" tubing. 4. Install a mechanical whipstock for an 11840' MD KOP. 5. Either a service coil tub~g'ffn-i't")ar the CTD rig will squeeze 15.8 ppg cement plug across all existing perfs. A minimum)~20 bb.!s,6f 15.8 ppg cement will be used. Cement will be washed down to the whipstock tray. ~ .......... Steps 2-4 will begin as soon as possible with the goal of having the whipstock set by April 5th.

Well house inspections were also conducted. The testing went well with Ron White as the BPX representative in charge of testing, 1.2 wells were tested with two failures witnessed, The pilot on NK-12A tripped below 50% of the separator pressure and was replaced and passed a retest, The SSV on NK-62 failed to hold D,P. and was stroked and passed a 'retest. I inspected 12 well houses and all were in order with no exceptions noted, The AOGCC test forms am attached for reference. S, UM,M. ARy,,.;. I witnessed SVS tests on 12 oil producing wells in BPX's Niakuk Field. t 2 wells tested, 36 components, 2 failures witnessed, 5.5% failure rate. 12 well houses inspected, ho.exceptions noted. ..

UM Btmhole Loc: 1491'NSL, 2752'WEL, Sec. 30, TI2N, RI6E, UM Dear Mr. Shultz: Enclosed is the approved application for permit to drill the above referenced well. The permit 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 permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface easing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Sinc,~v~ ~,,~ ! Robert N.

Surface - TD Gyro--Gyrodata continuous mode--during completion Drilline Hazards/Risks -- Reservoir Pressure This well will penetrate a portion of the reservoir supported by water injection from NK- 16. The last fall-off test indicated a reservoir pressure gradient of 9.8 ppg EMW. The maximum anticipated surface pressure is 4380 psi; based on a bottom hole pressure of 4865 psi at 9550' tvd and dry gas to surface. Close Approaches NK-16 and NK-17 are adjacent (at the surface) water injection wells to NK-62 and will be shut- in until surface casing is set. Well Control: Well control equipment consisting of 5000 psi WP pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures.
