National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Oilfields and Crude Oil Characteristics. Cook Inlet Basin, Alaska.

PB213875

Publication Date	1972
Personal Author	Blasko, D. P.; Wenger, W. J.; Morris, J. C.
Page Count	49
Abstract	The first well producing commercial quantities of oil in the Cook Inlet Basin of Alaska was completed in 1957. Since that time, oil production in the Basin increased rapidly and by the end of 1969 had reached an annual rate of 74 million barrels. Five major oilfields had been developed with two additional discoveries awaiting development. Estimated amounts of recoverable oil by primary and secondary recovery methods total 2.7 billion barrels, or 36 percent of the estimated oil originally in place. Repressurization by injecting gas or water in formations containing under-saturated oil has significantly increased the volume of recoverable oil. Production has all been from formations of the Tertiary age; and that much of it is from depths of 10,000 feet or more is unusual for Tertiary formations. The oils are low in sulfur and contain low to moderate amounts of asphalt. (Author)
