G-30A is a Zone 1/2 sidetrack that reaChe;} marginal GOR in 2004 and has cycled since then. During the past 12 months the on-time has been less that 20%. With no wellwork options, a sidetrack to a new area is planned. The sidetrack, G-30B, is scheduled to be drilled by Nordic 1 on or about Jan. 7. 2006. The plan calls for laying 17 ppg cement across the entire production liner to prep for a cement ramp exit in Zone 2 with the target in Zone lB. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference.

Telecopy # Confirm # G-30A Supplement Doyon #14 ~/~ 7/14/g`5 The 7" liner procedure for cementing went a~ording to plah up until the casing test procedure where an attempt to pressure up to 3`500 psi was made. A pressure of 3600 psi was reached and the pressure bled off to t 100 psi, A 9 5/8" RTTS with a set of ?" seals was run in the hole and the 7" seals were stung into the PBR on top of the 7 X 9,5/8" liner top packer. A pressure of 8,500 psi was held on the annulus, but the 7" liner would not test, The 9 5/8" RTT$ and 7" seals were POOH and a 7" R'I-rS was run to isolate the leak in the 7" liner. There was some problem with tight hole at 6470' (7" liner hanger) and the RTTS had to be worked through, The packer was set at 6479' (4' in the first joint under the liner hanger) and the 7" liner tested to 3000 psi. The annulus was then tested and a rate of 3 BPM @2000 psi was observed. The 7" RTTS was POOH and a 9 5/8" EZSV was run and set at 6400'. A volume of 31 Bbls of Neat Class "G" cement was squeezed away with a final pressure of 1100 psi, The cement was displaced to just below the EZSV, After unstinging and reversing out the EZSV was stung into again after several hours and a pressure test was made up to 2000 psi, The pressure held and did not bleed off, Once the casing was cleaned out another pressure test was performed to 2`500 psi which slowly bled off to 1800 psi.

As the attached AOGCC BOPE Test Report shows there was 1failure. The ball type floor safety valve leaked. The valve was replaced and tested before I departed the location. The location was clean and all excess equipment was stored properly and there was good access to all areas of the rig. The rig was clean and all equipment seemed to be in good working order.

The permit to redrill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole.

Cement the liner in place with the total cement volume based upon 50% open-hole enlargement plus the 80' shoe volume, 4 1/2"X7" lap volume and 150' excess on top of the liner with 3 1/2" drill pipe in the hole. Clean out cement to landing collar. RIH with drillpipe conveyed perforating assembly and perforate the well. POOH LDDP. Run the 3-1/2" L-80 completion string assembly using as much 3-1/2" used tubing and jewelry as possible. Space out and circulate with corrosion inhibitor. Install a BPV and test plug. Remove BOP's. Install and test the production tree to 5000 psi. Pull tree test plug and BPV. Set packer. Test the tubing x casing annulus to 3500 psi for 30 minutes. Shear RP valve in the upper GLM and freeze protect the well. Set aBPV. Release rig. RECEIVED Complete appropriate documentation and hand-over to Production. , 18. 19. 20. 21. 22. 23. 24. 25. 26. 27.
