ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Altemating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. ITEM 4b: TPI (Top of Producing Interval). The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 8: ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None". ITEM 29: List all test information. If none, state "None".

The well failed a MIT-IA in October 2003 due to corrosion, though the casing has passed a Combo-MIT. The well's remaining value will not support/" a RWO. The intent of the rig sidetrack is to restore C-17's integrity and provide an off-take point in the immediate drainage area. The sidetrack is currently scheduled for Nabors rig 2ES, beginning around June 25th, 2004, after the completion of the C-24A sidetrack. The pre-rig work for this sidetrack will begin at the Well's Group earliest convenience after sundry approval.

I. Supervisor o~1o%-~ I~ THRU: March 23, 2001 FROM: Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests PBF/PBU C Pad. Marc.h231 200.1' 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 ina 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'07A failed to hold D/P, 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 well C-05 and a slight crude oil leak from the SSV On 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, $ failures witnessed, and 11.9% failure rate. 21 well houses inspected. .Att.achme. nts' svs PBU C-Pad 3'23-01 JJ CC: SVS PBU C Pad 3-23-01 JJ Alaska Oil and Gas Conservation Commission Safety Valve System Test Report Operator: BPX Operator Rep: Merv Liddelow AOGCC Rep: Jeff Jones Submitted By: Jeff Jones Field/Unit~ad: PBF/PBU/C Pad Separator psi: LPS 174 Date: 3/23/01 HPS 662 Well Permit Separ Set L/P Test Test Test Date Oil, WAG, GINJ, Number Number PSI PSI Trip Code Code Code Passed GAS or CYCLV~ C-01 1720300 C-02 17'30040 662 550 5~5 P' P 'OIL C-03A 1981840: 662 550 530 P P OIL C-04A 1960920 662 ' 550 ' 220 3" P .....

Thc permit to rcdrill'docs not exempt you from obtaining additional permits required bv law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations arc made. Blowout prcvcntion cquipmcnt (BOPE) must bc tcstcd 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 contagtin~ thc G~m'ms~'o~n~ field inspector on thc North Slope pager at 659-3607.

The sidetrack, C-17A, will target the 14P sand. This sidetrack will be conducted in two phases. Phase 1: Lay abandonment cement and set whipstock: Planned for 2112/98. · D-15 has passed a tubing integrity test. The well has been drifted and a Kinley caliper has been run. · Existing perforations will be abandoned with approx. 20 bbls cement. Abandonment cement will be pressure tested to 1500 psi and tagged with AOGCC witness. · A permanent whipstock will be set on ELine at approximately 11,240' MD. Phase 2: Mill Window and Drill Directional Hole: Planned for 2116198. Directional drilling coil tubing equipment will be rigged up and utilized to mill the window and drill the directional hole as per attached plan to planned TD of 12,715' MD (8,850' 'l'VDss). Mud Program: - Phase 1: Seawater - Phase 2: FIo-Pro (8.8 - 8.9 ppg) Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 9795' MD and cemented with approx. 20 bbls. cement. The well will then be perforated with coil tubing conveyed guns. Well Control: - BOP diagram is attached. - Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. Directional - See attachments. - Kick Off: 11,240' MD (8,627' TVD ss) - TD: 12,715' MD (8,850' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run.
