Model of oil and gas formation on the example of Triassic deep sediments of the north of Western Siberia

Using the example of deeply immersed Triassic deposits in the north of Western Siberia, a model of formation of the oil-and-gas content has been created allowing us tracing all stages from the accumulation in the source suites to the oil decomposition and gas generation. The model also takes into account the reservoir formation and predicted hydrocarbon migration paths. The results of the work indicate the presence in the Triassic sediments of the independent generation-accumulation system and the existence of deep reservoirs. A phase forecast of the state of hydrocarbons is made depending on the depth of immersion of the rocks.
