Deeply Buried Sandstones - Diagenesis and Reservoir Quality

Abstract

SUMMARYDuring development of sedimentary basin, pore space of sandstones undergo transformations related to diagenetic stages. These processes include compaction, cementation, dissolution, replacement and recrystalisation, and become more and more advanced with depth. This interactions amends primary porosity, leading to deterioration of reservoir properties. The paper presents diagenetical changes occurred within deeply buried tight Rotliegend sandstones from Polish part of Southern Permian Basin and its impact on reservoir properties
