Background. The South Turgay basin has been extensively studied using geological and geophysical methods. To date, the discovery of large oil and gas deposits in its structural traps seems impossible. The deposits, which have been under development for a long time, demonstrate the trend towards depletion. Therefore, a search and exploration of non-anticlinal traps is becoming an important source of hydrocarbon reserves.Aim. To identify zones of non-anticlinal reservoirs and traps.Materials and methods. On the basis of three main criteria for predicting the development of nonanticlinal traps (stratigraphic, lithofacies and structural-tectonic), this paper presents the forecast zones for the development of non-anticlinal traps with oil and gas potential, taking into account the facies diagnostics of the deposits.Results. The traps of regional pinching-out, as well as possible traps of erosion-accumulative and accumulative subgroups, are predominantly developed in the trough. The traps of the regional pinch-out subgroup are most widespread in the Aryskum and Bosingen graben synclines. The traps of the accumulative subgroup are predicted mainly in the Bosingen and Akshabulak graben synclines.Conclusions. According to the obtained results, the South Turgay Basin possesses a significant oil and gas potential in non-anticlinal traps. Lithological reservoirs with thick and widespread mudstones confined to the Jurassic deposits are of particular interest.

Volcanic reservoirs have been overlooked for hydrocarbon exploration for a long time. Carboniferous volcanic rocks of the Zhongguai paleouplift contain proven reserves of [Formula: see text]. We have investigated the volcanic reservoirs integrating cores, well, and seismic data, and the proposed volcanic reservoir distribution is controlled by the weathering function, fractures, and lithology. The weathering process makes the originally tight igneous rocks become good-quality reservoirs, and fractures play an important role in connecting different types of pores and act as reservoir space. Isolated and ineffective pores become effective ones due to connection among fractures. Only volcanic breccia can be good-quality reservoirs without any weathering function. The nonlinear chaos inversion controlled by weathered layers shows that the good-quality reservoirs are distributed in the top of the weathering crust and the structural high. Furthermore, fluid-detection attributes and background information prove that oil and gas are distributed along the paleostructural high. The objectives of this study were to (1) describe the characteristics of volcanic reservoirs and determine the controlled rules for reservoir distribution, (2) characterize the distribution of reservoirs and hydrocarbon, and (3) propose an effective workflow for hydrocarbon exploration in volcanic rocks combining geologic and geophysical methods.

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.

The article presents results of the research of disjunctive dislocations of the earth's crust in northern part of the Sakhalin Island by analyzing the fields of lineaments, which identified on basis of satellite surveys using the LEFA software package. The object of research was chosen not by chance: eastern part of territory of the north of Sakhalin Island is quite well studied by geological and geophysical methods in order to identify oil and gas-bearing structures, as well as in connection with the close attention to it after catastrophic Neftegorsk earthquake on May 28, 1995. The result of work of the predecessors made it possible for verify the reliability of results obtained and assess of prospects to using automated decryption technologies to identify seismically active zones. The purpose of work was to create maps of active fault zones on studied territory. In process of the work, the SRTM data and Landsat-8 satellite images for 2015-2020, obtained in eight spectral channels, were analyzed using algorithms for detecting the location of lineaments based on methods of mathematical processing of images using different algorithms. It was revealed that images obtained in the red, infrared zones of the electromagnetic spectrum (4, 5, 6, 7), and the panchromatic channel (8) are most informative for identifying disjunctive disorders. Based on the data obtained, maps of disjunctive disorders of Sakhalin Island on scale of 1: 500,000 compiled. The article has certain novelty due to fact that the LEFA technological techniques were first used for research the geologically complex structures of Northern Sakhalin. The main results of the work will be useful in choosing places for construction of economic and industrial facilities, as well as in the exploration, search and operation of mineral deposits.
