Oil and gas production, and production potential, in the Cook Inlet Basin area of Alaska extends essentially from Kachemak Bay north to the mouth of the Susitna River. Sixteen dry natural gas fields have been discovered in that area, but only five fields are being actively produced. Total combined remaining reserves of all natural gas fields in the Cook Inlet Basin are estimated to be nearly 6.7 trillion cubic feet of gas. Included in this figure are the reserves of those fields that have not been developed for production, which total nearly 2 trillion cubic feet of gas. Dry natural gases in the Cook Inlet area consistently exhibit low sulfur content and high btu characteristics, making the gas ideal as a fuel for power generation as well as domestic heating and cooking. All production is from Tertiary formations.
