Abstract

This article investigates the geological and structural-tectonic characteristics of Cretaceous deposits in the eastern part of the southern margin of the Fergana Depression. The main objective of the study is to clarify the structural configuration of Cretaceous deposits and identify new prospective oil and gas exploration targets through an integrated interpretation of three-dimensional seismic survey data (UCHNU–3D) and available drilling information. Structural maps of Horizon XVI of the Ustritsa Formation were analyzed, and the geological characteristics of four local structural zones, namely Chimiyon–Khonqiz, Avval–Karmakol, Andijan–Polvontosh, and Khartum, were evaluated. Particular attention was paid to anticlinal and hemianticlinal structures, fault-sealed blocks, tectonic discontinuities, and their influence on the formation and preservation of hydrocarbon accumulations. The results indicate that the structural-tectonic framework of the Cretaceous deposits is predominantly characterized by fault-block and fold-block structures. The distribution of hydrocarbon accumulations is associated with the combined influence of lithofacies variations, structural closures, and tectonic faults. The Oybuloq, Quyi Chimiyon, Zilol, and Yangi Avval structures were identified as prospective targets for further geological exploration. The findings provide a geological basis for prioritizing oil and gas exploration activities in the Fergana Depression and selecting promising exploration targets while considering geological risks..
