In compliance With 20 AAC 25.170 Section (a), "Within one year of suspension or abandonment of an on- shore well", all clean up work is to be finished. Section (b) provides the means for an extension of time if a valid reason exists. Section (c) provides for on site inspection. Consequently, we are presenting the following list of your abandoned and/or suspended wells. ~{any of these are now more than one year old and are not in compliance with regulations. Others should have the final inspection completed, this summer while weather permits. This list covers the years 1975 to date. There may be some earlier wells that .also need inspec- tion. If you have any earlier wells to be inspected this summer please inform us. Therefore, we are requesting a schedule from you for this summer, when our field insFectors can accompany your representa- tives to these sites for the final clean up inspection.

Smith Commissioner Ben LeNorman Petroleum Inspector April 2, 1981 Witness Plug and Monday, March 9 - I departed my home at 7:50 a.m. for an 8..20 a.m. showup and 9:20 a.m. departure via Wien Flt. %1 for Deadhorse arriving at il:00 a.m. weather; -9°F, light wind, light snow. A call from Doug Amos in Anchorage advised me that plugging for abandonment of Arco's West Sak %20 was underway. I immediately contacted Arco..Drilling Foreman, Don McKelvey at that location. He advised the lower plug (Plug %1, Sheet #6 of attachment) had Just been pumped. I then drove to the lo~ation which is 22 miles southwest of Ar¢o's K~paruk Camp.. Later in the evening I witnessed pumping of Plug %2 (Sheet %7 of attachment). I witnessed no further ope~ations on this Job due to other commitments at Pump Station %1 and West Sak %16. However, I was in regular contact w~th the drilling foreman in charge. Tuesday, March 10 - Inspect analyzer skid piping and bench test solartron at Pump Station %1, the subject of a separate report. W~ednesday., March 11 - Inspect Prover ball at Pump Station %1, the subject of a separate report. Thursda.y, March 12 - Standing by on West Sak %16. Friday, March 13 - B.O.P.E. Test on West Sak %16 completed, the subject of a separate report. Saturday, March 14 - I dep~rted Deadhorse via Wien Flt. %10 at 12:05 a.m. arriving in Anchorage ~t 1:40 a.m. and at my home at 2:10 a.m. In summary, I witnessed setting of Plug %2 across the surface casing shoe at Arco's West Sak. %20.

Commlsskm Anchorage DETERMINATION OF PRESSURES Ae Be 20" 2000 psi Diverter System The 20" diverter syst~ is required only to divert flow away from the drilling rig and has limited pressure control capabilities due to the shallow setting depth of our 16" conductor (80'). Any unexpected flows between the permafrost interval and 10-3/4" shoe 1650-2700 would be controlled by circulating the hole with weighted mud. 13-5/8" BOPE Equipment Anticipated reservoir press, in the U. Kuparuk Interval is 3335 psi~ (Determined from RFT and production test data on development and earlier W. Sak wells). Formation inte. grity (frac gradient) has been determined to be in the order .7 psi/ft from leak-off and formation tests. As a result the maximum pressure the BOPE could see prior to surface shoe breakdown is 1890 psi. DIRECTIONAL WORK This well will not be directionally drilled. Its natural course will be monitored with single shots @ 500' intervals during drilling as re- quired by DOG regulations. A continuous Gyro will be run after setting ~?" casing if the well is to be completed. JAN2 0 1981 Alaska Oil & Gas Cons.
