The oil and gas bearing capacity perspectives of Kura intermountain depression crystalline basement
N.R. NarimanovThe possibility of prediction of crystalline basement oil-gas bearing capacity perspectives in Kura intermountain depression is considered. About 450 oil and gas accumulations have been revealed almost in every continent and the oceans shelves in the upper layer of the crystaline basement. They are confined to the platform areas and intermountain depressions. The analysis conducted on the basis of new global tectonics conception provides a ground to suppose that the formation of oil and gas accumulations in the crystalline basement is the result of geological-geodynamical processes interaction in the sedimentary cover and crystalline basement. The sedimentary cover, paleographic and paleotectonic conditions, presence of oil and gas accumulations in intermountain Kura depression indicate to its relatively high oil and gas producing potential. All of this allow to predict the possibility of oil and gas saturation in void spaces of the crystalline basement. It is known that formation of hydrocarbon accumulations in the crystalline basement is controlled not by structure factor, but its accumulating properties. In this connection the complication of the sedimentary cover and Kura depression crystalline basement via intersecting net of the deep faults and smaller disjunctive allows to predict relatively wide development of crush zones and fracture in its crystalline basement and oil-gas bearing capacity of Mesozoic effusive as a possibility of saturation of these zones with hydrocarbons.
