Abstract

Summary

The increasing complexity of the hydrocarbon resource base structure determines the consistent increase in the urgency of the problem of identifying and developing non-anticlinal oil and gas deposits. in this regard, the agenda is the problem of studying the factors that control the formation of accumulations of oil and gas. The results of comprehensive studies of the developed deposits indicate the existence of limited connectivity between the sediments, the accumulation of which was carried out in various facies zones. in addition to sedimentation conditions, the possibility of formation of hydrodynamic barriers inside the reservoir determine the epigenetic transformations of rocks. The most frequently encountered phenomenon is recorded in carbonate sediments. in the stressed zones, intensive leaching of carbonate material occurs, which is deposited in the immediate environment, which negatively affects the movement of hydrocarbons within the natural reservoir. This creates favorable conditions for the formation of traps. This phenomenon, in some cases, contributes to the formation of non-conductive low-amplitude faults. The paper presents the typification of factors contributing to the creation of frontier deposits on a level with the structural plan.
