A fish was left in the well at 9758' MD, 8554' TVD. A EZSV plug was set at 9350' MD and was press~u, re tested to 3000 PSI, then drill pipe was stung into EZSV and 15,000 r~~.~f weight was applied to the plug. After pressure test and weight test was made, 77 barrels of cement was squeezed below the retainer, an adequate amount to fill from the top of the fish to the retainer; pulled out of retainer and spotted 15 bbls of cement above the retainer, an adequate amount to fill to 9200' (150'). After four hours, the plug was tested to 3000 PSI, ok. A master valve and back pressure valve were installed at the surface. SUMMARY: I witnessed the satisfactory plug and abandon of that podion of PBU 18-29 containing the fish. STATE OF ALASKA .....

After drilling to 9970' MD with mud losses ranging from 1-6 BPM, the lost circulation rate increased to 4-5 BPM. A lost circulation material (LCM) pill was spotted across the loss zone and the drill string was pulled into the 9- 5/8" casing at 9437' MD. 2. While tripping back to TD to spot a second LCM pill, fill was encountered at 9951' MD, while picking up the kelly to wash to bottom the drill string stuck. 3. After jardng without success, the drill string was backed off at 9758' MD. 4. A jarring assembly was screwed into the fish. This jarring operation was also unsuccessful. The jarring assembly was backed off and recovered. 5. An EZSV cement retainer was set at 9350' MD and pressure tested to 3000 psi. 6. The well was plugged by squeezing 300 sx Class 'G' cement below the retainer. 7. After unstinging from the retainer, 75 sx of cement was dumped on top of the retainer. 8. The top 2000' of hole was displaced to a non freezing fluid. 9. The 13-3/8"x9-5/8" annulus was down squeezed with 146 bbls of dry crude. 10. The BOPE was nippled down. A 13-5/8" 5000 psi dry hole tree was nippled up and tested to 1500 psi. 11. The rig (Doyon #9) was moved to PBU DS 18-27.

The permit to drill 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 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.

Final angle at this depth is 90 degrees. Set 7" liner and cement same. PU 6" BHA and clean out 7" liner; test to 3000 psi for 30 minutes. Drill 6" hole to TD of 12055'md/8771'tvd in the 226.52 degree direction. Run and set 4 1/2" slotted liner and production packer. Circulate well to brine. Run 4 1/2 x 3 1/2" or 3 1/2" tubing string. Freeze protect well. NU tree and test to 3000 psi. Release rig. DS18-29 Operations Summary-State Permit CKH NOTES: The annulus will be left with a non-freezing fluid during any extended period. Wells within 200' of the proposed well are: DS18-01: A distance of 33' at 3000'md* DS18-02: A distance of 82' at 3612'md* DS18-03: A distance of 61' at 4037'md* DS18-19: A distance of 68' at 1220'md* *depths are referenced to DS18-29 The drilling fluid program and fluid surface system will conform to the regulations set forth in 20AAC25.033. The maximum surface pressure is based upon the BHP and a full column of gas to TD (0.10 psi/ft). Based upon previous logs obtained from DS18 wells, no productive zones are anticipated above 4000'tvd. No hazardous levels of H2S are anticipated in this well.
