The following summarizes the procedure required to prep C- 20a for extension drilling and is submitted as an attachment to Form 10-403. A schematic diagram of this proposed completion is attached. 1. A Tubing Integrity Test on 7/15/00 was successful. 2. On 7/5/00 C-20a was drifted to 11,892 slm. 3. C-20a will be killed with seawater and 8.7 ppg Flo-Pro prior to using drilling coil to mill the existing 4 ½" float equipment and drill an extension of approx. 1,946 ft into Zone 1 (13P). 4. The extension will be completed with a cemented 2 7/8" liner that will overlap the existing 4 ½" liner by approx. 1300 ft. to cover existing C-20a perforations. Drilling coil is expected to complete summer rig maintenance and move onto C- 20 on August 1, 2000.

The permit to rcdrill docs not exempt you from obtaining additional permits required by laxv 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 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. David W.

The target polygon is bounded to the north and south by east/west faulting (10-30 ft of throw) and to the east by a north/south graben (15-30) ft throw. The target maintains >500 ft of standoff from these faults and is in a relatively flat, unfaulted block. C Pad is not a designated H2S pad; the last sample taken was 18ppm (12/95) C-20A Short Well Summary Pre-Rig Operations: Note: original KBE was 67.20", BF elevation is 34.30' 1. Notify AOGCC prior to commencing P&A Operations. Note: Due to the poor condition of the 5-1/2" tubing, the final P&A of perforations will occur later with the drilling rig (Doyon 16). 2. Make a chemical cut with the 4-7/16" chemical cutter in the 5-1/2", 17.0#, L-80, BTRS AB/MOD tubing at 9100' MD (note: refer to tubing tally summary. This cut will be in the middle of a full joint) 3. Circulate and kill the well with sea water. 4. Freeze protect well with diesel to 2000' MD. 5. Test pack off and service lock down studs. Report results to rig supervisor as soon as possible. Lock open or pull SSSV. 6. Install a BPV and test same. 7. Remove the electrical lines, well house and flow lines. Prepare for rig arrival by leveling pad and digging out cellar. 8. Please provide total well preparation cost on the hand over form. Rig Work: . . o . o . 10. 11. 12. 13. 14. 15. MIRU, verify pack off has been tested or retest. Pull BPV. Circulate the well to remove freeze protection and any trapped gas. Set and test TWC to 1000 psi. ND tree, NU and test BOPE. Circulate Seawater. Pull and LD 5-1/2", 17# tubing to pre-rig cut depth (~9100' MD). (The tubing is cut here due to the KOP being planned at 9000' MD and a tubing restriction ,-,9140' MD) Ensure that the bottom hole can take fluid (inject through remaining tubing). Run and set a 9-5/8" EZSV on Baker 20 setting tool (w/CCL). Set the EZSV at 3' below a casing collar as near as possible to 9030' MD (planned KOP is 9000'MD) Once the EZSV is set perform a casing integrity test to 3500 psi for 30 minutes. PU EZSV stinger (plug catcher just above EZSV stinger) on 5" DP. RIH to EZSV and sting in. Establish injection rate into perforations from 12414-12458' MD. Mix and pump 76 bbls - 372 sacks - of class "G" cement (calculated as 7", 26# casing capacity from PBTD to TOL + 150' of 9-5/8, 47# casing capacity + 15 bbl to squeeze into perfs), displace with seawater to place cement from 11555' MD to PBTD at 12521' MD.
