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

Prior to CTD sidetracking, the 5-1/2" L-80 tubing will be replaced with 4-1/2" 13Cr-80 tubingf. The sidetrack, 7-33B, will kick off from a window milled off a mechanical whipstock. The lower Romeo Zone 1A will be the target for the sidetrack. The following describes work planned to prepare 7-33A for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed tubing swap and sidetrack is attached for reference. 1. Combo MIT tubing/inner annulus to 3500 psi. / 2.

The BOP test was much improved over the last test witnessed on this rig. They are performing the test by written procedures which offers consistency between crews. The rig is still having maintenance problems which is inherent to a concept rig and is basically still in the construction phase. They are not prepared for cold weather and have plans to make it ready for winter but they are running behind. SUMMARY: I witnessed a BOP test on CDR #1, 0 failures, 4 hours.
