Occurrences of Oil and Gas Seeps: Alaska Peninsula, Alaska, Western Gulf of Alaska.
NTIS: PB 253 013 :78 pages
The Bureau of Mines investigated two areas of the Alaska Peninsula (Iniskin Peninsula and Becharof Lake) where oil and gas seeps were known to occur in an attempt to determine (1) whether the seeps are still active and (2) the amount of bitumen contained in the drainage leaving the seeps. The oil, water, oil-water, and gas were sampled and analyzed. Five oil samples were taken at four separate oil seeps. The api gravity of the oil ranged from 8.9 Deg. to 21.4 Deg. and the sulfur content was from 0.12 percent to 0.59 percent. Four of the seven gas samples obtained revealed fairly high caloric values, ranging from 746 to 924 btu/cu ft, and averaging 844 btu/cu ft. A total of 44 water samples were obtained. Bitumen content of the water was as high as 9,773 mg/l at one seep, but averaged less than 1 mg/l where the seep-drainage water entered the Gulf of Alaska.
