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). ITEMS: 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". ITEM 29: List all test information. If none, state "None".

This well targets the " Southeastern part of DS15 2 offsets South of the midfield_~raben. . ,..' ,/ I The sidetrack is currently scheduled for Nabors rig (2SS; beginning around August 21 S\ 2004, after the completion of the 07-06B sidetrack. The pre-rig work for this sidetrack will begin at the Well's Group earliest convenience after sundry approval. Current Condition: ,/ Passed MITOA to 2000 psi and fail CMIT TxlA on 4/13/03.

(5) The well t5-11A was kicked off @ 10737' MD (8471' TVD), on Run 1, from the wellbore originally drilled for Well 15-11. (6) Well 15-1lA was drilled to TD @ 12278' MD (8771' TVD) on Run 15. The'TD depth was adjusted to 12278' MD (8771' TVD) from 12271' MD (8771' TVD) after a tie-in. (7) The interval from 12256' MD (8771' TVD) to 12271' MD (8771' TVD) was not logged due to the Gamma Ray sensor to bit offset.
