| This paper examines the petroleum bearing potential of the northwestern Chardzhou Step of the Bukhara-Khiva region of the Republic of Uzbekistan, encompassing the Gugurtli-Uchkyr and Kandym uplifts, and the opportunity for expanding the hydrocarbon resource base. The relevance of this study is determined by the leading role of the Bukhara-Khiva region in hydrocarbon production and reserve growth, as well as the high level of exploration of Jurassic carbonate strata, while exploration of terrigenous Jurassic, Cretaceous, and Paleozoic rocks on the Chardzhou Step remains insufficient. The aim of this study is to comprehensively analyze the geological and tectonical conditions, stratigraphic confinement, trap types, and resource base of hydrocarbon accumulations in the study area, assessing the prospects for their further development. Data on 34 discovered hydrocarbon fields is summarized, their classification is provided, and the conditions under accumulations formed in Jurassic and Cretaceous carbonate and terrigenous strata are characterized. Based on an analysis of the number of prospective and predicted hydrocarbon resources, an estimate is made of the potential increase in commercial reserves. It is concluded that the northwestern part of the Chardzhou steppe has high petroleum potential and that it is advisable to intensify exploration, primarily in the Cretaceous and terrigenous Jurassic strata, as well as in the Paleozoic. Keywords: carbonate strata, terrigenous strata, Jurassic, Cretaceous, Paleozoic, hydrocarbon field, petroleum bearing potential, hydrocarbon resource, Chardzhou stage, northwestern part of the Bukhara-Khiva region, Republic of Uzbekistan. |
