Set screw which holds the slip sleeve was not sheared (expected weak point -- 700 Ibs shear rating). Cable simply pulled through the slips (slips were new for this job). Also, after rebuilding the same head assembly on the bench, BHI was able to pound the cable through the slips without sheering the screw. Possible that OD of cable is slightly reduced -- normal for this type of armored cable over time. Will install another washer to crimp cable tighter. Now, the slack management issue -- this was performed before this well and the cable moved back only about 3' - 4', and it was not pumped forward after reheading (pumping forward at surface is a step which we rarely perform). 10:30 - 14:00 3.50 STWHIP N DFAL WEXIT Cut CTC, stab onto well.

Set an inflatable plug assy and possibly a mechanical whipstock using 1 %" s ... ice. ..f1at 12,200' and 12,025' respectively. Setting of the whipstock may be left to the rig to pe /- ... Operations thereafter will be conducted by the rig. Steps 1-2 will be performed between now and the beginning of Feb. Drilling coil is scheduled to mill the window and drill the sidetrack on Feb 5th, 2003. /' h,~v~ rl!fr Sherwood CTD Drilling Engineer SCANNED JAN 2 4 2003 CC: Well File Terrie Hubble l'Rf:..= WELLHEAD = ACTUA TOR= KB.

I. Supervisor O"\/o~ - 0 \ March 23, 2001 THRU: FROM: Jeff Jones, Petroleum Inspector SUBJECT: Safety Valve Tests PBF/PBU CPad March 23. 2001: I traveled to Prudhoe Bay Field to witness Safety Valve System tests on BPX's C Pad. Well house inspections were also conducted. Merv Liddelow was the BPX representative in charge of testing, and performed the tests in a professional manner. Twenty-one wells on C-Pad were tested with five failures witnessed. The SSV on well C-04A tripped below 50% of the separator psi, the SSV on well C-07 A failed to hold DIP, the pilot on well C-19B was frozen, the pilot on well C-20B failed to trip and the SSV failed to hold DIP. Mr. Liddelow indicated to me that all failures were repaired within 24 hours. I inspected 21 well houses and noted leaking wing valves on wells C-03A, C-13A and C-19B. A hydraulic fluid leak on the SSV control line of weft C-05 and a slight crude oil leak from the SSVon well C-25A were also noted. Mr. Liddelow indicated he would have these items corrected. The AOGCC test forms are attached for reference. SUMMARY: I witnessed the SVS tests on twenty-one oil producing wells on C Pad in the Prudhoe Bay Field. 21 wells tested 42 components, 5 failures witnessed, and 11.9% failure rate. 21 well houses inspected.

The permit to redrill does not exempt you from obtaining additional pennits required by law from other govemtnental agencies, and does not authorize conducting drilling operations until all other required pennitting determinations are made. Blowout preventìon 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 Conuuission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Conmlission petroleum field inspector on the North Slope pager at 659-3607. dlf/Enclosures cc: Department of Fish & Game, Habitat Section w/o enc!.

Hazards and Contingencies On drilling the initial well in 1 988, they incountered lost circulation when getting into the Sadlerochit. Geology stated that the problem was a fault that was drilled acrossed. This sidetrack has tried to take this into account and should drill away from that fault.
