The permit to rcdrill does not exempt you from obtaining additional pcrmits required by laxv 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.

Intended Procedure: · P&A existing interval. Install mechanical whipstock at 9110'. Mill window from whipstock through both the 3-1/2" and 5-1/2" liners at 9110' md. Drill 10' of formation and perform leak-off test to 9.0 ppg, 0.5 ppg above the highest anticipated mud weight (8.5 ppg polymer mud). Crossing of faults are anticipated. If lost circulation is excessive and cannot be controlled with lost circulation material, plan on drilling ahead with water without returns. Directionally drill a conventional 2-3/4" (3" bi-center) well to access Zone 1 reserves. Planned TD is 9799' md. · Run 2-3/8" blank liner to TD, cement in place. · Perforate, place on production. Drilling fluids will be injected into disposal wells at Pad 3 or CC2A. ~ March 16, 1999 DS 5-01C Potential Drilling Hazards POST ON RIG No H2S production has been measured from this well.

(6) The section from 9778' MD (8709' SSTVD) to 9804' MD (8721' SSTVD) was relogged due to a malfuntion while restoring the data. (7) Well 05-01C was drilled to 10130' MD (8930' SSTVD) on Run 13. The TD was depth shifted to 10145' MD (8930' SSTVD) after a tie-in. (8) The interval from 10113' MD (8917' SSTVD) to 10130' MD (8930' SSTVD) was not logged due to sensor to bit depth.
