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".

Our rig BOPE Test tracking records indicated that Rig 14's BOPE test had not been witnessed since Feb 1, 1995, therefore i traveled to the rig to witness their test. When I arrived on location I found the rig crew in the process of replacing the annular preventer bonnet hydraulic seals, delaying the commencement of the BOPE test until 5:00 PM. The test was plagued with a slow, recurring test pressure leak off. Numerous BOPE and Choke Manifold component isolations were performed before it was determined that the leak was around the test plug and through the test pump block valves. This leak detection, component repairs and an inexperienced drilling crew resulted in a test time of 16 hours. As the attached AOGCC BOPE Test Report indicates, in addition to the test plug and test pump block valve leaks, there were three failures, the 2 APl ring failures were repaired during this test. The lower rams were replaced and retested on 4/4/95. Well C-SA is not designated as a H2S well, therefore the H2S detectors were not tested. However i did review the electrician's gas detector calibration log and I recorded the last calibration date in the remarks column on the BOPE Test Form.

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.
