The results of the analysis of geological exploration work and gas and oil bearing of independent gas and oil bearing District Northwest Caucasus and information about completed neotectonic investigations. The results allow to specify fault-block the structure of the region and adjacent territories (the West Kuban foredeep, Kerch-Taman interpericlinal deflection and Adygea projection), highlight the ring and polygonal structure, local uplifts and prospective areas of oil and gas accumulation. The largest prospects of oil and gas bearing are associated with the joint area of the Northwest Caucasus in the West Kuban foredeep. V.V. Drozdov [5] established the dependence of oil and gas bearing of structural traps on the density of lineaments and recent tectonic activity on the example of the Central Caucasus. According to him, 73 % fields of HC are confined to areas with an average density of lineaments. In areas of extreme values, and significantly lower than the average density, the empty structure mainly distributed. These data show the availability of lineament density index to assess the quality of the protective properties of rocks and oil and gas bearing of local areas. The foregoing data show a large role in shaping the fields of oil and gas MCL of vertical hydrocarbon migration and shielding properties of rocks. Therefore, a further study the factors of its oil and gas bearing and evaluation of prognostic resources should pay particular attention to the identification and study of impermeable layers. You must map the most promising local uplift with the latest available geological and geophysical materials and if necessary by reinterpretation of geological and geophysical data on the areas allocated fairly confident based on neotectonic studies.
