Background. The development of the oil and gas industry in the Caspian region is closely linked with the development of oil and gas resources of the Caspian Sea and adjacent territories. According to historical sources, it was in the Caspian region where the global offshore oil production was launched. Further, other countries used the experience gained in the Caspian region. Four main stages can be distinguished in the of the Caspian oil and gas complex, including the nascent (antique and medieval eras) stage; the initial stage of industrial development (from the 10th century to 1917); the Soviet stage of industrial development; and the modern stage of industrial development.Aim. To study of the history of the development of the oil and gas industry in the Caspian region.Materials and methods. The methods of retrospective, graphical, statistical, system-structural analysis were used in the work.Results. Based on the results of the study, the main stages in the development of the oil and gas industry in the Caspian region were identified.
SUMMARYBased on the results of modeling the generation processes of emigration and accumulation of hydrocarbons reconstructed the history of oil and gas accumulation in the sedimentary cover in the region. Determine the location of possible hydrocarbon generation sources in the sedimentary cover, migration paths, the phase composition of HC, the intensity of hydrocarbon saturation within individual zones and tectonic structures.
This paper provides the results of geochemical studies with products of mud volcanoes conducted for a purpose of evaluating the generative potential of the South-Caspian basin. The kerogen types have been identified for different stratigraphic intervals and stages of the organic matter (OM) thermal maturity have been determined. A correlation has been established between the generative potential and the basin deposition and subsidence rate.
Introduction. The study of the conditions for the development of discontinuous disturbances makes it possible to draw conclusions that in the formation and destruction of various deposits, they are connected by discontinuities different in the mechanism of their formation. The lithological composition of the rocks in contact with it has a certain significance for assessing these gaps in relation to the formation or disbandment of deposits. The main role here is played mainly by clay sections, the material of which fills the cracks, preventing the destruction of hydrocarbon deposits in individual suites (Middle Pliocene deposits).Aim. Identification of conditions for the formation of traps and deposits of oil and gas within western Turkmenistan.Materials and methods. Analysis of published literature and factual data.Results. Thus, discontinuous disturbances are the most important factor in the formation of deposits and play an exclusively creative role, forming oil deposits of a tectonically shielded type.
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.
