The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102.

As the attached AOGCC BOPE Test Report shows there were 2 failures, both were APl ring failures. Both of these leaks were repaired and retested OK. The location was clean and all excess drilling equipment was stored properly. The rig was clean and all of the equipment seemed to be in good working order. NOTE: While witnessing the BOPE test I noticed that the conductor pipe had dropped down hole approximately 1 foot. I ask the ARCO rep., John Rail and the Nabors toolpusher, Mike Downey, when this occured. Both of them said they didn't know. They both had noticed that it had dropped,, but said that it must have occured on the other shift. -r'/~,:r ~ ~, ~,[e ~o~f,,,-'~,~,,.

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.
