When structural forms are of weak morphological intensity (5-10m), there exist two difficulities in indentification and outlining of hydrocarbon deposits: complexity in mapping of tectonic elements and a significant effect of lithological and tectonic factors on a possibility of the deposit formation. Complex analysis of geological and geophysical data was performed in the surveyed area for the outlining of oil deposits. The work resulted in identification of Devorian graben-shape troughs (linear structures of tectonic origin weakly defined in the modern structural plan) probably are the shielding elements. seismic record analysis in the pay formation interval bedding enabled to forecast a change in the section, lateral distribution of deposits with improved porosity and permeability propeties.
