THE COMPOSITION AND PHYSICOCHEMICAL PROPERTIES OF RESERVOIR-ROCKS OF SPAN SERIES OF THE PRIBUG STRUCTURE OF THE PODLESSE-BREST DEPRESSION

Abstract

The results of laboratory studies of the composition and physical properties of span series rocks of the Pribug structure within the eponymous underground gas storage (UGS), have been presented. The rocks are represented by a finegrained quartz sandstone with various sorting and grain roundness, type of cementation and clay content. The character of section suites changes for the material composition of the rocks and their physical properties have been set. The examined properties specify reservoir rocks characteristics which are widely used for integrated geophysics well data interpretation, geological and hydrogeological UGS modeling, making recommendations for increasing efficiency of pore volume usage during gas storage operation. Rock intervals with poor porosity and permeability are detected inside the examined rock series.
