Abstract

Gas hydrates have been inferred to occur in 50 North Slope exploratory and production wells. Most North Slope gas hydrates occur in six laterally continuous lower Tertiary sandstones and conglomerates; all these gas hydrates are geographically restricted to the area overlying the eastern part of the Kuparuk River oil field and the western part of the Prudhoe Bay oil field. The volume of gas within these gas hydrates is estimated to be about 1.0 ?? 1012 to 1.2 ?? 1012 m3 (37 to 44 tcf), or about twice the volume of conventional gas in the Prudhoe Bay field. Geochemical analyses of well samples suggest that the inferred hydrates probably contain a mixture of deep-source thermogenic gas and shallow, microbial gas. -from Author
