Annotation:

The objects of scientific research are hydrocarbon traps of the Upper Devonian-Tournaisian age on the territory of the Nozhovskiy ledge of the Perm region. The purpose of the study is to establish the features and patterns of filling the traps of the T₀, T₁ and T₂ formations with hydrocarbons to increase the reliability of the forecast of oil and gas potential and the assessment of the resource base.

The article analyzes the geological characteristics of traps of both prepared structures and deposits of industrial analogues, as well as non-industrial and unproductive traps. As a result of the study, a number of geological factors have been identified that affect the degree of filling of traps with hydrocarbons.

Taking into account the results obtained, it is possible to make a forecast of the degree of filling of traps, which allows to increase the reliability of the forecast of resources at prospective elevations, as well as minimize the risks of non-confirmation of resources.
