Five Cook Inlet fields account for a total present output of more than 145,000 bpd, and collectively have estimated producible reserves in excess of 750 million bbl. One of 15 geologic basins in the state, the Cook Inlet basin has an area of 9,500 sq miles lying approximately 45% offshore, 15% in tidal area, and 40% onshore. The basin's Cenozoic stratigraphy generally is represented by a maximum thickness of 25,000+ ft of nonmarine Tertiary rocks. Mesozoic limestone, marine clastic sedimentary rocks, and volcanic rocks unconformably underlie the Tertiary. Major structure and fault systems trend N.-NE. Tectonism occurred throughout the Mesozoic and Cenozoic and continues into the Recent. Faulting and folding are most prominent in the NW. part of the basin close to the Alaska Range. Oil has been found in the classic anticlines. Faulting and stratigraphic variations in part control accumulation and fluid properties. All reservoirs contain undersaturated oil close to bubble-point pressure requiring early secondary recovery efforts.
