Sr Petr Engineer SUBJECT: Wellbore plugs Unocal Nicolai Creek Permit No. (~3-~ 9f Exploratory Sec 32,TllN,R12W,SM Friday. September 6. 1991: I traveled to Nicolai Creek Unit to witness the plugging of well #4. Two plugs had been set prior to my arrival. Plug #1 was set through a 2-7/8" tubing cement retainer at 7009' (perfs at 7083-87') up into 9-5/8" annulus with 108 sx of class Plug #2 was also set through tubing retainer at 4240' and squeezed through perfs at 4294-98' with 108 sx of class I was met at the wellsite by Unocal representative Marry Lynch. After replacing a packoff that had washed out, we were able to get 2000 psi on the #2 plug saturday afternoon, but it bled down to 1850 psi in 30 minutes. The pressure had been applied through tubing and out an open gas lift mandrel at 2054'. The mandrel was located below the old surface plug and above the #2 plug. When we pressured up between the two plugs, the 1000' surface plug broke dOwn and a small quantity of gas and oil was observed at the surface. Unocal perforated the tubing at 996-1000' and circulated one barrel of crude oil. Number 3 plug was then set: a balanced plug from i000' to 50~ inside the 2-7/8" tubing with a coil tubing unit.. The plug (5.5 bbls of 15.8 ppg class "G" cement) was in place by 01:35 Sunday; however, it would not set up. After several futile attempts, the plug began to set and we were able to tag it with 1000 lbs at 357' after a 16-hour WOC. .The #4 plug was set to the surface at 21:15 with 26 sx of class cement. I saw it placed, but did not wait for it to set up. I asked Marty to take photos of the P&A marker in place before they backfill and send them to our office. In summary, I witnessed that the abandonment procedures were performed satisfactorily on Nicolai Creek #4 well. Location clearance will have to be performed later. 02-00lA (Rev. 6/89) 20/ll/MEMO1.PM3 STATE ()F ALASKA ~SKA OIL & GAS CONSERVATION CO~ ,SION Plug & Abandonment Re~ort Date Company Repr ~/~ ~Z~./ ~_ y A/C.4 Drilling Permit Sec.

Workover I traveled to the west side of Cook Inlet to witness a BOP test on Grace Rig #211 which was preparing to drill out a surface plug on Unocal's well Nicolai Creek #4. When I arrived, the crew was just finishing rigging up. Once the test was under way, things went fairly smooth with no failures noted. There were no provisions made for reserve pit tankage, and the blooey line was in the general direction of the inlet. At my request, Mike McCall had the line changed, and it now points down the location which is partially bermed. I was assured that by the time the rig was ready to test again, there would be tankage of some sort. The location was quite clean and orderly, considering ..t~ e amount of activity; and it appeared that the tool pusher, Mike Murray, was attempting to anticpate all possible problems. In summary: The BOP test Went well on Grace Rig #211 with no observed failures.
