Item 5: Indicate which elevation is used as reference (where not otherwise shown) for depth measurements given in other spaces on this form and in any attachments. Item 16 and 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 16, and in item 24 show the producing intervals for only the interval reported in item 27. Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval. Item 21' Indicate whether from ground level (GL) or other elevation (DF, KB, etc.). Item 23: Attached supplemental records for this well should show the details of any multiple stage cement- ing and the location of the cementing tool.

Commissi~r; Anchorage G-12 Daily Operations Cement Plug / Set Whipstock / Mill Window 6/2/96 Bullhead killed the well with 613 Bbls of filtered seawater. Tagged TD and corrected to E-line TD of 10,481'. Laid in 16 Bbls of class G cement and squeezed to 2000 psi. Live reversed out cement to 10,270' and made jet passes across 10,270' - 10,000'. Made a final reverse out and pressure tested the plug to 2000 psi, held solid. POOH keeping hole full. LWSl with 850 psi on the tubing. 16 bbls CMT - Class G wi .33% FL-33 + .1% CD-32 + .35% R-11 + l ghs FP-6L Fluid Loss: 120.5 cc/30 min. Thickening time 6:20 + I hr surface. 6/5/96 Arrived on location. Tied-in to CBL (7/10/81) and oriented whipstock 13° left. Set whipstock and 6/6-9/96 Run BHA#1 w/3.8" mill and 3 ft flex joint. Ran and set mill on XN nipple at 9235' as depth reference. Broke through in around 20 seconds. Felt bit grab and bump through. Milled up and down 5 times with no further resistance. Saw casing contact at 10234' dn (10230' up). Several stalls with high overpulls. Got in a bind at 10234' and pulled to 33K to get free this stretched the coil and made depth reference a bit tricky. Milled 3' down from casing contact. It felt like the mill jumped out of the casing. POOH and checked depth ref. at XN. CT stretched 3'. Changed bit and removed flex joint. RIH and check depth ref.: Reset to XN depth at 9235' since new mill is hanging up. Mill XN 5 times up and down with no real problems and continue down to whipstock. Found casing contact at 10234'. Mill down to 10241'. BHA#3 with Formation Mill and 2 string mills ran and this also hung up at XN' at 9235'. Tied in depth and start milling, Stalled twice and reamed up and down to polish the profile. Ran down to casing and saw casing contact at 10234' again. Very difficult milling due to gauge on formation mill being slightly oversize. Felt like bottom of upper string mill was catching. Very slow progress. Decide to dry tag and got through obstruction. Start milling and make headway. Stalling when back reaming through problem area. Final depth.was 10251' CTMD down tag with pumps on which corresponds to 10251' ELMD. The hole is 6' outside window. No progress was possible below this depth. 3000 LB set down without stalling. Feels like BHA is hanging up on whipstock. Milled up and down 10 times after getting to TD and the hole was smooth. Circulated 380 bbls seawater to help minimize solids. Freeze protected top 500' with MeOH. The formation mill had a small hole in the center about 3/4" deep. Looks like it was milling on some metal left at the bottom of the window. The sides of the formation mill showed some heavy wear and the string reamers showed wear on the sides but less than normal owing to the slightly oversized carbide on the formation mill. There was also heavy wear on the bottom of the upper string reamer which corresponds to the high stalls at the bottom of the window. RECEIVED NOV 2 9 1996 Naska Oil & Gas Cons.

Dear Mr. Reileyz Enclosed is the approved application for permit to drill the above referenced well. Well samples and a mud log are not required. A directional survey is require4. If available, a tape containing the digitized log information shall be submitted on all logs for copying except experimental logs, velocity surveys and dipmeter survey s. Many rivers in Alaska and their drainage systems have been classified as important for the spawning or migration of anadromous fish. Operations in these areas are subject to AS 16.50.870 and the regulations promulgated thereunder (Title 5, Alaska Administrative Code). Prior to commencing operations you may be contacted by the Habitat Coordinator's office, Department of Fish and Game. Pollution of any waters of the State is prohibited by AS 46, Chapter 3, Article 7 and the regulations promulgated thereunder (Title 18, Alaska Administrative Code, Chapter 70) and by the Federal Water Pollution Control Act, as amended. Prior to Mr. R. H. Reiley PruOhoe Bay Unit G-12 -2- May 26, 1981 commencing operations you may be contacted by a representative of the Department of Environmental Conservation. To aid us in scheduling field work, we would appreciate your notifying this office within 48 hours after the well is spudded. We would also like to be notified so that a repre- sentative of the commission may be present to witness testing of blowout preventer equipment before surface casing shoe is drilled. In the event of suspension or abandonment, please give this office adequate advance notification so that we may have a witness present. Very truly yours, ~o~ B .H.
