The oil and gas industry plays a key role in the economic development of the Republic of Kazakhstan, and strategic planning of prospecting and exploration of new fields also plays an important role in this process. The national oil and gas company KazMunayGas (KMG), represented by its subsidiary KMG-Barlau, is actively engaged in geological exploration of promising regional areas in the main oil and gas basins of the country. Research within the framework of geological exploration of subsoil is of a scientific and technical nature, and is aimed at poorly studied areas of promising regions. As a part of this research, KMG is conducting studies in five promising areas within the Aktobe (Mugodzhary block), West Kazakhstan (Berezovsky block), Mangistau regions (Zharkyn, Bolashak and North Ozen blocks). This project is carried out using modern technologies both when performing field seismic work and at the stage of processing and analyzing the obtained data in order to reduce uncertainties and geological risks. Most of the seismic work was completed in March 2024. Some areas are currently undergoing processing and interpretation of the new data acquired. The seismic work is expected to be completed by 2025. This article presents preliminary results as well as basic assumptions of the prospectivity of potential hydrocarbon deposits within the selected projects, with the total geological potential of the resource base estimated at approximately 3 billion tons of oil and gas equivalent.
