“…The study of the deep structure of the Ustyurt region in order to determine the prospects of oil and gas potential began in 1960. In the 70s, as a result of the introduction of seismic exploration by the OGT method, it became possible to explore the pre-Jurassic deposits of the region [1].…”

This article compiles and presents the tangible records encompassing drilling operations, testing procedures, and geophysical loggings conducted in the Ustyurt oil and gas region of Uzbekistan. These consolidated materials provide a comprehensive overview of the exploration efforts undertaken in this region. The dataset includes information on core samples extracted from drilling, their subsequent analysis, and the outcomes of tests conducted on intervals within the Pre-Jurassic deposits. Through a meticulous examination of core samples, drilled wells, and geophysical loggings, the study delves into the reservoir properties of rock formations in this geological region. The research identifies distinct groups of rocks within the Pre-Jurassic complex, categorized by their porosity characteristics. This categorization serves as a foundational step in understanding the geological composition and potential reservoir properties of these formations. An important outcome of this analysis is the identification of five distinct types of reservoirs based on the structure of the pore space within the pre-Jurassic sediments. This categorization holds immense potential for future predictions and assessments concerning these sedimentary deposits. By amalgamating core data, geophysical readings, and testing outcomes, the research contributes to a holistic understanding of the geological attributes and reservoir potential of the Ustyurt oil and gas region. This foundational information sets the stage for informed decision-making in exploration, production, and resource management activities within this significant geological area.

As a result of the stress state of the lithospheric block, a structure of orthogonal cracks may appear as a network of straight or arcuate topographic elements of the regional extent on the Earth’s surface—lineaments. In the last decade, one of the directions of lineament analysis had been the identification of the so-called transverse structures using remote sensing methods, which often serve as the geological boundaries of crustal blocks. Various lineament analysis methods are being actively developed: image enhancement, manual digitizing methods, and automatic extraction using software and algorithms. Revealing the relationship between lineaments and their characteristics with natural and anthropogenic processes is the relevant task. The tectonic lineament network is associated with deep faults and, in particular, ore regions that can be localized at the intersection of large lineaments. Therefore, most studies of increased accumulation of lineaments are carried out in areas where mineral deposits and groundwater deposits are identified. These areas include the Fergana region, which is one of the five oil and gas regions of the Republic of Uzbekistan. The presence of a fund of promising traps justifies the need for comprehensive geoinformation support, including satellite methods, and the possibility of transition to automatic methods for analyzing tectonic processes. Therefore, in this study, an automated lineament analysis was carried out in order to identify and interpret the transverse structures in this region. The study period (May–November 2019) was chosen to take into account the intensive exploration work in the region and the technical parameters of the images (without clouds). Landsat 8 satellite images were processed by the automated method of lineament structures interpretation in the LEFA program in the MATLAB environment. During the visual analysis of the processed images, it was identified that there was a temporary change in the number of lineament structures by month. At the same time, the northwestern part of the region (Namangan region) is characterized as the zone of the strongest manifestation of lineament structures. Further detailing of the lineament structures in terms of direction and orientation made it possible to determine the transverse structures. Thematic maps with the geospatial location of transverse structures showed that the nature and clarity of transverse structures varied depending on the features of the geological structure of the sections they intersected.
