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".

The first leg (18-27a) was drilled in early 1998 but was placed high in formation and went straight to gas. The second leg 18-27b was drilled late in 1998 but communicated to the old wellbore. A cement sqz gas shut off attempt was not successful. The final leg 18-27c was drilled 10/00. It was placed primarily in ZlA with a toe up into ZlB. It produced full-time for 6 months before the thin LOC came into play and it went to cycle performance. At present 18-27c does not heal and has very low remaining value in this Ivishak drainage area. 18-27C has been selected for a through tubing sidetrack with the SLB/Nordic 1 Coiled Tubing Drilling rig on or around September 15,2005. The sidetrack, 18-27D, will exit the existing 4-1/2" liner from a whipstock in Zone 1B ~nd will target Zone 1A sands. The existing perforations will be isolated by a CIBP and the liner cement job.1-ne following describes work planned and is submitted as an ' attachment to Form 10-403.

This lateral sidetrack was completed in a thin oil column primarily in Zone 1 A with a short toe into Zone 1B. The well quickly went to high GOR and was therefore placed on cycled production. During the last year of production, GOR ranged from 35 -40 MSCF /STB. While on cyclic production, the well produced 300 -500 BOPD. Assuming an ultimate marginal GOR of 80 MSCF /STB, the limiting oil rate will be about 300 BOPD. Estimated remaining reserves are less than 100 MSTB. The new sidetrack will access the same zone as this completion. I recommend approval of this sundry request.
