ITEM 1: Classification of Service Wells: Gas injection, water injection, steam injection, air injection, salt water disposal, water supply for injection, observation, injection for in-situ combustion. ITEM 5: Indicate which elevation is used as reference (where not otherwise shown) for depth measurements given in other spaces on this form and in any attachments. ITEM 16 AND 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 16, and in item 24 show the producing intervals for only the interval reported in item 27. Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval. ITEM 21: Indicate whether from ground level (GL) or other elevation (DF, KB, etc.). ITEM 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, Other-explain. ITEM 28: If no cores taken, indicate 'none'.

The coil sidetrack, U-15B, will kick off from a window milled in the horizontal section of the existing Zone 4 lateral through 5.5" liner, after cement squeezing the existing perfs. The U-15B target is Zone 4. The well was previously permitted for sidetracking in September 1999 (permit no. 99-87, sundry no. 399-172). The permit no 99-87 called for drilling out the shoe and running a slotted liner completion. During the prep work our records revealed a drill collar had been included in the shoe of the existing wellbore. It was found (prior to the milling operation) that the drill collar could not be milled out and the sidetrack was cancelled. A new directional plan has been developed and the well is back on the drilling schedule. The following describes work planned to prep for sidetracking and is submitted as an attachment to Form 10- 403. A schematic diagram of the proposed sidetrack is attached for reference. 1. Gas lift mandrels have been dummied off. 2. Master valve, wing valve and tree were successfully tested to 5000psi. 3. Wellhead seals were tested for integrity. 4. Tubing integrity was verified. 5. Caliper tubing and liner. 6. Tubing and liner drifted with service coil. 7. Service coil will set a mechanical whipstock at approx. 9990' in the 5.5" liner. 8. Service coil will lay in approx. 30 bbls cement & squeeze to shut off all existing perfs. 9. Service coil may then mill out the cement down to the whipstock and mill the window if timing permits. This work will commence on approx. Oct ;1,~, 2001.

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/fO. c. Based on previous logs on U Pad, no hydrocarbon zones are anticipated above the Sag River. .~ d. No potential hazardous levels of H2S are anticipated in this well. e. Drilling hazards: · Previous wells have experienced losses into a small sand at around 4500' TVD. The sand is believed to be discontinuous with a small capacity and losses have cured themselves. · The Cretaceous may be affected by GC2 injection and overpressures of up to 150 psi are possible at around 4600' TVD. b, Well Plan Summary Page 4 7-5/8" INTERMEDIATE CASING CEMENT PROGRAM - BJ SERVICES CASING SIZE: 7-5/8" CIRC.
