Main types of reservoirs of pre-jurassic deposits in the Ustyurt region

Abstract

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.
