The article discusses the conditions for the formation of oil and gas complexes (oil and gas play) in Aryskum trough. Geological and geophysical data of deep geological structure confirm that formation of sedimentary basin and lithological-stratigraphic complexes, oil and gas complexes (oil and gas plays) of Southern Torgay was influenced by the rift-induced geodynamic regime of oil and gas formation. The stages of rifting are divided: pre – rift, initial – formation (early Jurassic), middle – subsidence (early-middle jurassic) and final (late jurassic), which are associated with the formation of jurassic productive horizons. The Cretaceous productive horizons were formed during the epirift stage. The rift mode of oil and gas formation assumes high warming of the subsurface and conditions for the migration and accumulation of hydrocarbons and confirms the prospects for searching for hydrocarbon traps in the Aryskum trough.
