OIL AND GAS GEOLOGICAL DIVISION INTO DISTRICTS OF THE FRAME OF THE NORTHERN AND CENTRAL CASPIAN SEA AND ITS WATER AREAS
Studying of regularities of placement of accumulations of oil and gas in the Areas of Ciscaucasia and in general the region many researchers were engaged, but still single scheme of its oil and gas geological division into districts it isn't developed. There are even discrepancies by a region provision in system of oil-and-gas provinces of the South of Russia. One researchers consider the region as the independent Ciscaucasian oil-and-gas province, others include a northern part of the region in structure of the Ciscaucasian and Crimean province, and southern, occupying the advanced deflections, - in the North Caucasian province, the third consider this region a component of the single North Caucasian and Mangyshlaksky oil-and-gas province. The existing discrepancies on allocation of oil-and-gas areas (NGO) and areas concern dimension, rank hierarchy of the allocated oil and gas geological divisions that is connected with use of various tectonic basis answering to representations of their authors. Characteristics of zones of oil and gas accumulating and distribution of UV in them are insufficiently researched and found out. The zones of oil and gas accumulating and factors determining placement of oil and gas in them in G.T. Yudin's works are most fully characterized.
