THE CHARACTERISTICS OF PORE SPACE IN LOWER TRIASSIC SANDSTONES OF THE WARSAW REGION
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2019, Vol 474, Issue 474
Abstract
Reservoir and sealing properties of Lower Triassic sandstones from seven boreholes of the central part of the Koszalin-Zamość Synclinorium were investigated in terms of potential levels for underground storage of carbon dioxide. Extensive petrographic studies, image analysis, and investigations of petrophysical properties of rocks and pore space were carried out. The research shows that diagenetic processes both variously affected the intensity of alteration and variously shaped the pore space. Not only primary but also secondary porosity, resulting from diagenetic alteration and dissolution, is observed in the rocks. Microscopic observations revealed that the pore space in studied samples is dominated by macropores. The results obtained indicate a poor suitability of the Lower Triassic deposits for the purpose of carbon dioxide sequestration.<br/><br/>
