Comparisons between Petroleum Systems in the Arctic National Wildlife Refuge, Alaska.

摘要

The geology of the Coastal Plain of the Arctic National Wildlife Refuge (ANWR) in northeast Alaska indicates that the area has high potential for the accumulation of oil and gas. Discoveries peripheral to, and oil seeps and stains within the area, suggest three petroleum systems are active. Oil, condensate and gas are present in lower Paleozoic basement, lower Cretaceous sandstones and upper Cretaceous to Tertiary turbidite sandstones at the Point Thomson Unit immediately west of the Arctic Wildlife Refuge. Available analyses indicate the oil in the Cretaceous sandstones correlates to the oil from the Prudhoe Bay field and peripheral fields.
