Zeolite mineralization of reservoir rocks in the north of Western Siberia: lithological and geophysical aspects and exploitation characteristics

As the hydrocarbon production tends to decline, formations with a complex geological structure and various secondary mineral formation types of reservoir rocks gain a considerable attention. The importance of secondary minerals for formation of pore and void space structure in hydrocarbon reservoirs is extremely high. The physical and chemical properties of these minerals should be considered during exploration works, calculation of reserves, reservoir engineering, wellwork planning. This article highlights the methodological study approach of mountain rocks with zeolitization based on the results of modern lithological, analytical, and laboratory research. The implementation of the approach allowed for recommendations for rapid quantitative assessment of zeolite content in the Lower Cretaceous sediments of the Bolshekhetskaya Depression.
