Historic and Genetic Fundamentals of Kazakhstan Sedimentary Basins Oil and Gas Potential

Oil and gas potential historic and genetic fundamentals of Kazakhstan different-typed sedimentary basins are broadly considered. Based on sedimentation volume rate the basin gradation has been accomplished in regards of potential resources and large field discovery probability. For each oil and gas–bearing or oil and gas prospective basin oil and gas source rocks have been identified and main phases of oil and gas generation in the light of geological history of the basin have been traced. Hydrocarbon generation and accummulation spatial and temporary relations as the fundamental factors of sedimentary basin oil and gas potential forecast are ascertained. It has been clearly noted that sedimentary basin oil and gas prospectivity is determined by its evolution staging, and the favourable evolution stages are considered.
