ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. ITEM 4b: TPI (Top of Producing Interval). ITEM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None".

A PDS caliper run in October 2002 indicated damage severe enough to warrant a tubing replacement to put the well back into service. A RWO was judged to be uncompetitive and a rig ST found to be the well's best option. The well is designed to access a shallow north-south trending BSAD graben with the main target~ the Zone 1 A sand. A cast- iron bridge plug will be set and tested in the 2 3/8" production liner above the existing perforations during ¡? the pre-rig work. After completing horizontal section a fully cemented 150' liner lap will complete the P&A .,// of the existing perforations. All current perforations are in the Ivishak Zone 1. ~/ The sidetrack is currently scheduled for Nabors rig 2ES, beginning around January 20th, 2004, after the completion of the 15-14Bsidetrack. The pre-rig work for this sidetrack will begin at the Well's Group earliest convenience after sundry approval.

Mill window from cement. Directionally drill a horizontal well from the existing wellbore. Complete with 2-3/8" cemented liner. Perforate appropriate intervals. Intended Procedure: · P&A existing perfs with 17 ppg cement. Leave top of cement at 9325'. Mill window in 7" liner at 9355' md. Drill 10' of formation and perform Leak off test to 9.0 ppg, 0.5 ppg above the highest anticipated mud weight (8.5 ppg FloPro). Directionally drill 2-3/4" x-~1980' horizontal well to access Romeo reserves. · Run 2-3/8" blank liner to TD, cement in place. · Perforate, place on production. October 21, 1998 DS 15-0lA Potential Drilling Hazards POST ON RIG · H2S production is not anticipated from this well. BHP: 3400 psi ~ 8800' ss (7.4 ppg EMW), BHT 190 °F (estimated values based on offset wells). No over pressured zones are anticipated. Maximum anticipated WHP w/full column of gas: 2500 psi. Gas saturated intervals are expected in build section. · No major faults or loss circulation zones are anticipated.

(4) Well 15-0lA is represented by runs 4, 5, 6, 7, 8, 9, 10, 11 and 12 which are all Directional with Gamma Ray. (5) The well was initially kicked off @ 9354' MD (8694' TVD), through a window cut in the casing. (6) The well was kicked off on Run 4 from the wellbore originally drilled for Well 15-01, @ 9354' MD (8694' TVD) . (7) Run 1 through run 3 were milling runs, and no logging data was acquired in new hole. (8) The break in the log from 10754' MD (8895' TVD) to 10800' MD (8891' TVD) was due to a depth adjustment of 46' applied after a tie-in. (9) The break in the log from 10945' MD (8888' TVD) to 10957' MD (8888' TVD) was due to a depth adjustment of 12' applied after a tie-in. (10) The break in the log from 11202' MD (8880' TVD) to 11211' MD (8880' TVD) was due to a depth adjustment of 9' applied after a tie-in. (11) The interval from 11369' MD (8874' TVD) to 11392' MD (8874' TVD) was not logged due to the sensor to bit offset. (12)Well 15-0lA was drilled to TD @ 11392' MD (8874' TVD) on Run 12.
