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".

Julv 19. 1999: I traveled to ARCO's DS 15-20A Well and witnessed the weekly BOPE test on the Dowell/ Nabors 3S coil tubing drilling rig. As the attached AOGCC BOPE Test report indicates the test lasted 3 hours and there were no failures. The gas detectors were not tested due to the late hour of the test but had been calibrated on 7/17/99 and appeared to be operating properly. The rig and Coil tubing unit were clean and all related equipment appeared to be in good \^IOrking order. Summary: I witnessed the weekly BOPE test on Dowell/Nabors 3S coil tubing drilling rig.

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.

The TO was depth shifted to 10872' MD (8797' SSTVD) after a tie-in. (6) The gap in the log from 9833' MD (8789' TVD) to 9845' MD (8789' TVD) was due to a depth adjustment applied after a tie in. (7) The interval from 10823' MD (8794' STVD) to 10840' MD (8796' SSTVD) was not logged due to sensor to bit offset. (8) The Gamma Ray log has been depth shifted to match the Schlumberger MCNL Gamma Ray logged on 26 July 1999.
