AP19175313 Analysis of hydrocarbon systems and assessment of the oil and gas potential of Paleozoic sediments of the Tasbulak trough of the Shu-Sarysui basin under conditions of uncertainty based on basin modeling

Relevance

The Shu-Sarysui basin is the only predominantly gas-bearing basin in Kazakhstan, but its hydrocarbon potential has not been sufficiently studied. Modern geological exploration methods, including 2D seismic exploration and computer basin modeling, make it possible to fill in data gaps and identify promising areas of oil and gas accumulation. The research is aimed at improving the efficiency of the search and development of low-carbon energy sources, which is important for meeting the domestic needs of the country and the development of its energy sector.

Purpose

Reconstruction of the history of the formation of hydrocarbon systems and establishment of patterns of distribution of hydrocarbon resources within the Paleozoic sediment complex of the Tasbulak trough based on 2D seismic survey, deep drilling and minimal amount of geochemical information.

Expected and achieved results

 

Based on the research results, new ideas about the structure, formation composition, and conditions of hydrocarbon generation in the sediments of the Middle-Upper Paleozoic of the Tasbulak trough have been substantiated. For the first time in the sediments of the Middle-Upper Paleozoic, a large Central Tasbulak shaft of the northeastern strike has been identified in the constructed 3D model of this trough, characterized by the spread of undeformed or weakly deformed hydrocarbon systems, conformally deposited marine and lake genesis, which demonstrates in many ways the preserved original UV potential. The development of carbonate structures (reef type) is predicted within this shaft. In addition, the concept is characterized by fundamental scientific novelty, according to which the deposits of the quasi-platform sedimentary cover of the Tasbulak trough have a high potential for gas and oil production, which is confirmed by the development of reservoirs with good filtration and capacitance properties, the presence of regional and zonal chemogenic and sulfate-argillite tire rocks of increased capacity, and the spread of gas and oil-producing formations.
