High ambient temp. swings caused intermittent flaring & forced a reduction in production rates. Ambient temp up 5°F. High ambient temp. swings caused intermittent flaring & forced a reduction in production rates. Ambient temp up 6°F.

Alaska 99519-66 I 2 .~ ··EG .;FFAIRS Dear Ms, Cooke: Wc have receivcd your IcUcr of Novcmber 28. 1994 requesting additional flare volume for the Endicott oil pool production facijity in the Duck Island Unit (DIU). The additional flarc "olume is rcquired during tcsting of the reccntly rcpaircd gas compressors. The Commission hereby approvcs flaring up to 30 MMcf of gas ovcr and above the dcsignated safety flare of thc Endicott production facility. Flaring is expccted to commcnce on or about November 29. 1994 and continue until work is complete. It is understood that gas flaring will be kcpt to a minimum whenever possible. and all volumes will be reported monthly on Alaska Oil and Gas ConseryaLÌon Commission form 10-422. DONE at Anchorage.
