Signed Terrie Hubble PBU K-09B Well Number Title 197-086 304-233 Technical Assistant Permit No, 1 A roval No. INSTRUCTIONS Prepared By Name/Number. Drilling Engineer: Terrie Hubble, 564-4628 Mary Endacott, 564-4388 GENERAL: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-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). ITEM 8: 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 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".

BP EXploration (Alaska) MEMORANDUM State of Alaska Alaska Oil and Gas Conservation Commission TO: THRU: Julie Heusser,-.-'-~,~- ~,~-~ Commissioner Tom Maunder, P. I. Supervisor ¼/~:s~©''' FROM: Chuck Scheve; SUBJECT: Petroleum Inspector DATE: April 20, 2001 Safety Valve Tests Prudhoe Bay Unit KPad. Friday, April 20, 20.0!: I traveled to BPXs K Pad and witnessed the 30-day retest of the safety valve systems. As the attached AOGCC Safety Valve System Test Report indicates i witnessed the testing of 11 wells and 22 components with 3 failures. The pilots on wells K-06, K- 07 and K-09 tripped below the required set point. The pilot on well K-09 was retested and operated properly. Wells K-06 and K-07 normally flow into the Iow- pressure system (at 200 to 300 psi) but were recently switched into the high- pressure system. The pilots on these two wells were left in the iow pressure setting (125 psi) and tdpped near this set point but were failed on this test due to the higher flowing tubing pressure required to produce into the high pressure system. These two pilots were adjusted to the higher set pressure (550 psi) and retested at this time. Merv Liddelow performed the testing today; he demonstrated good test procedures and was a. pleasure to work with. A walk through inspection of the well houses on this pad was performed during the SVS testing with no problems noted. All well houses inspected were reasonably clean and all equipment appeared to be in fair conditions. Summary: I witnessed the 30-day retest of the safety valve systems at BPXs K- Pad in the Prudhoe Bay Field.

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. 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.
