Tagged T.D. at 11370ftMDCTU. Performed Injevctivity test at 4bbls/min at 1300psig. Pumped 5bbls of Fresh water spear,12bbls of class G cement and a 5bbl fresh water spacer, displaced with sea water. Could not get a electronic pressure response on well head pressure in unit. Found hose from sending unit to CTU cab evacuated but 1000psig on BOP gage. Shut down pumps. Reestablished pumping but the only response was an increase in inner annulus pressure. POH and rigged down. Did not freeze protect well or flowline due to the fact CTU or cut & Kill operation will be back on well in 24hrs.Estimated cement top is at 11035ftmdbkb. BBLS.

Mr. T. N. Tyler Manager Reservoir Operations Standard Alaska Production Company P. O. Box 196612 Anchorage, AK 99519-6612 Dear Mr. Tyler: By letter dated'September 24, 1986, Standard Alaska Production Company has requested waivers of productivity profiles required by Conservation Order 165, as amended by Conservation Order No. 213, in wells JX-2, B-30, Y-20, G-29, G-27 and Y-21. The Alaska Oil and Gas Conservation Commission has reViewed the need for productivity Profiles in these wells. The Commission has determined that these data are not necessary for proper monitoring of the Prudhoe Oil Pool performance. Therefore, by administrative approval authorized by Conservation Order 213, Rule 2, the Commission waives productivity profile ~requirements in Prudhoe Bay Unit wells JX-2, B-30, Y-20, G-29, G-27 and Y-21.

Se permit to drill does not indemnify you from the probable need to obtain additional permits required by law from other governmental agencies prior to commencing operations at the well site. To aid us in scheduling rield work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface .casing shoe is drilled. ~ere a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness, testing before drilling below the shoe of the Conductor pipe. c.

We did not experience any surface gas during the drilling of the 17-1/2" hole on Well Y-22 and believe it is unnecessary to continue the use of the 20" Hydril diverter system on Pad Y. We, therefore, request that Rule 4(b) of Conservation Order No. 145 be waived for Y Pad. Very truly yours, SOHIO ALASKA PETROLEUM COMPANY R. S.
