Summary

In the Middle Kura depression hydrocarbon deposits and oil and gas formation centers are located in layers composed of Maikop and Eocene terrigenous deposits. Here, the reservoirs formed in coastal-marine conditions are located mainly in the bottom layers of the reservoirs and are replenished with oil and gas due to the in-situ migration of hydrocarbons.

In the South Caspian Basin, oil and gas deposits were formed as a result of the migration of hydrocarbons from the centers of their formation into sedimentary-type traps (lithological-stratigraphic) with the participation of eruptive channels of mud volcanoes. Here, reservoirs of coastal marine origin are located mainly in the wing of anticlinal uplifts, usually in one of them, inextricably linked by mud volcanism.

An analysis of this factual information made it possible to draw a conclusion on the probability of discovering deposits in areas of the South Caucasus that are not covered by mud volcanism. It is assumed that deposits at such objects can be formed as a result of migration from the source of hydrocarbon formation to the lower horizons of the productive strata along fractures. At the same time, the possibility of formation of deposits in the sedimentary layer, in which the center of hydrocarbon formation is concentrated, is predicted.


Keywords: terrigenous deposits, mud volcano, fluid migration, anticline, reservoir
