(MD) Inspection Type' Side-Track Candidate Inspection ORIGINAL COMMENTS ' This survey was run to assess the condition of the tubing with respect to corrosive and mechanical damages. The caliper recordings indicate that the tubing ranges from good to fair with respect to corrosive wall penetration. Most of the tubing appears in good condition, with recorded penetrations falling below 20% wall thickness and no recorded cross-sectional wall loss in excess of 8%. Penetrations ranging from 21% to 39% wall thickness are recorded in 44 joints between 3,100 ft. and 8,500 ft. Most of the damage appears in the form of line corrosion, with the deeper recorded penetrations appearing as isolated pitting. The distribution of corrosive penetrations recorded throughout the tubing string are illustrated in the Body Damage Profile sheet of this report, and cross-sectional drawings of the pipe at the location of the deepest recorded penetrations are also included.

The sidetrack, 15- 34a, will kick off from a window milled from a mechanical whipstock to be set in Zone 2. The 15-34a target is lower Zone 2. The following describes work planned to prep 15-34 for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack completion is attached for reference. 1. The tubing tailpipe will be plugged and both tubing and inner annulus will be pressure tested. 2. A dummy whipstock drift will be run on slickline. 3. A PDS calliper will be run to verify tubing condition. 4. E-Line will set a mechanical whipstock at approx. 10,850' MD in the 5 Y2" liner. 5. Service coil will pump approx. 20 bbls cement to shut off existing perfs below the whipstock. E-line is scheduled to set the whipstock on Sept. 14. Service coil will carry out step 6 on Sept. 15-16, 2000 pending approval of the Sundry Notice. Ted Stagg CTD Drilling Engineer CC: Well File Petrotechnical Data Center -_. STATE OF ALASKA ....

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.

The drilling fluid program and surface system will conform to the regulations set forth in 20AAC25.003. Maximum surface pressure is based on BHP and a full column of gas to TD (0.10 psi/ft). Based on previous logs on DS15 Pad, no potential productive zones are anticipated above 7800' ss (Put River). No potential hazardous levels of H2S are anticipated in this well.
