Ulmishek, G

The Barents-northern Kara shelf, one of the largest continental shelves in the world, is still in the earliest stage of exploration for oil and gas. During the last several years, numerous seismic surveys have been conducted, a number of wells have been drilled, and several gas fields have been discovered. This report summarizes the geological data gathered during recent exploration activities and presents the changes in earlier concepts necessitated by consideration of these new data. The revised assessment of undiscovered petroleum resources is based on new information about the distribution and quality of source rocks and reservoir rocks and the structural framework of the shelf. Special attention is paid to evaluating the oil versus gas potential of the shelf, an evaluation that strongly depends on the expected offshore extension of oil-source facies in the Lower-Middle Triassic section. The most probable amounts of undiscovered petroleum resources of the shelf are estimated at 14.2 x 10/sup 9/ barrels of oil and 312.2 x 10/sup 12/ cubic feet of gas. The Finnmark trough, the south Barents and North Novaya Zemlya depressions, and the offshore continuation of the Timan-Pechora basin possess the great majority of these resources. 103 refs., 12 figs., 1 tab.
