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.

This sidetrack will be conducted in two phases. Phase 1: Lay abandonment cement and set whipstock: Planned for 8/'1/98. · C-26 has passed a tubing integrity test. The well has been drifted and a Kinley caliper has been run. · Existing perforations will be abandoned with approx. 20 bbls cement. Abandonment cement will be downsqueezed through the annulus of the 4 %" x 7" straddle in order to stabilize the 4 %" tubing for milling and to abandon existing perforations. Abandonment cement will be pressure tested to 1500 psi with AOGCC witness. This procedure is described in more detail in the Form 10-403. · A permanent whipstock will be set on ELine at approximately 11,270' MD. Phase 2: Mill Window and Drill Directional Hole: Planned for 8~7~98. Directional drilling coil tubing equipment will be rigged up and utilized to mill the window and drill the directional hole as per attached plan. Mud Program: -Phase 1: Seawater - Phase 2: FIo-Pro (8.8 - 8.9 ppg) Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 11,100' MD and cemented with approx. 20 bbls. cement. The well will then be perforated with coil tubing conveyed guns. Well Control: - BOP diagram is attached. - Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. Directional - See attachments. - Kick Off: 11,270' MD (8,617' TVD ss) - TD: 12,788' MD (8,960' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run.
