Prospects for the oil and gas content of the Upper Permian deposits of the southwestern part of the Vilyui syneclise based on the analysis of sedimentary environments and geochemical conditions of oil and gas content

The article discusses the prospects for oil and gas content of Upper Permian deposits in southwestern marginal part Vilyui syneclise. In this margin, terrigenous complex with proven productivity central syneclise, pinches out. study area, represented by monoclinal slopes is considered a promising area exploration non-structural hydrocarbon traps Paleozoic sediments. objectives include identifying general patterns sediment formation, associated mainly development alluvial complex, substantiating potential opportunities migration accumulation hydrocarbons predicted traps. research based on interpretation latest seismic surveys prior-years geological geophysical data. Authors carried out structural paleo-structural analysis, identified lithofacies well log, generalized analyzed geochemical conditions deposits, traced pinching margin also outlined areas river valleys that form zones advanced reservoirs. results studies have validated syneclise non-anticlinal drew up diagram deposits. obtained are interest prospecting under study.
