PREPARED BY: W.A. Shepherd Sperry-Sun Drilling Services Logging Systems Anchorage, Alaska The following information was derived from in house evaluations of well cuttings caught at the Nabors 28E rig site during the drilling of well 11-30. The lithological evaluation was performed for the Horizontal / Slimhole section. The Engineer and Sample Catcher on location performed their duties on a twelve hour tour basis. The method of lag calculations used for depth tagging is considered crude, but fairly effective with limited operational means. Sample evaluations were performed by W.A. Shepherd, Sperry-Sun Drilling Services' Geologist/Logging Engineer, inhouse at our Anchorage lab. W.A. was able to give an interpretive analysis of lithology by utilizing FE/MWD data recorded from the wellsite.

Friday, June 3, 1994: The test was delayed until 6:00 AM due to casing pack off problems. As the attached AOGCC BOPE Test Report indicates, there were no failures. However the H2S Detection System was due for calibration. I was contacted on 6/4/94 and informed that the system had been calibrated. I found the rig equipment and location in good' condition.

The permit to drill 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) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.
