Hydrocarbon systems in the Turkmen sector of the South Caspian basin

Introduction. The paper considers conditions conductive to the formation and location of oil and gas accumulations in the Turkmen sector of the South Caspian Basin.Aim. Modeling of hydrocarbon systems of the Turkmen sector of the South Caspian Basin.Materials and methods. Statistical generalization and systematization of the data and materials presented in reference literature, field sources, and archive data, as well as published works of Sh.F. Mekhtiev, I.S. Guliev, M.Z. Rachinskii, S.S. Dzhibuti, S.A. Aliev, V.Yu. Kerimov, V.V. Kolodiya, etc. Data modeling was performed using the PetroMod software.Results. As a result of numerical modeling, the formation conditions of hydrocarbon systems and their main elements, i.e., oil and gas source strata (OGSS), reservoirs and seals, were determined. Oil and gas prospects were identified, and the main spatial and temporal patterns in the development of generation, migration, and accumulation processes of hydrocarbon fluids, as well as the formation conditions of traps were established. In addition, a map was created to illustrate potential prospective zones, objects, and “plays.” Oil-and-gas prospects were determined, and the main areas of oil-and-gas exploration in the Turkmen sector of the Caspian Sea were substantiated.
