Abstract
Increasing the efficiency of geological exploration at different stages is associated with improving accounting methods and minimizing geological risks. This requires an analysis of hydrocarbon systems and their elements (oil source strata, container rocks, impermeable seals, and traps) and dynamic processes (generation, migration, and accumulation of hydrocarbons). The presence of an active hydrocarbon generation-accumulation system (GAHS). The Anadyr trough is confirmed by numerous oil and gas shows and fields identified in its land part. The Anadyr trough is located in the Bering Sea. Geochemical studies of sedimentary rocks and fluids have shown that deposits of the Upper Cretaceous, Paleogene, and Neogene can be the source of these hydrocarbons. The results of seismic-geological correlation and the performed paleogeographical reconstructions showed that the area of development of probable source rock would spread to the area of the water zone, where an improvement in their generation properties is predicted. An assessment of geological risks was performed in the search and exploration of hydrocarbon deposits. The paper has tested a methodology for assessing geological risks for geological exploration in the Bering Sea.
