 en Modeling gas–rock–water interactions in carbon dioxide storage capacity assessment: a case study of Jurassic sandstones in Poland
Labus, K.; Tarkowski, R. & Wdowin, M.

Abstract

This paper presents the results of the modeling of gas–rock–water interactions for reservoir formation of one of potential geological carbon dioxide storage sites in the Polish Lowlands (Chabowo Anticline). The modeling performed with the use of a geochemical simulator was preceded by mineralogic-petrographical and petrophysical analysis of sandstones sampled together with pore water at the depths of 856–857 and 1,240–1,241 m. The study focused on determining the changes in rock matrix and reservoir parameters that take place as a result of carbon dioxide injection, and on the assessment of the formation suitability for carbon dioxide storage. The results have shown that in the analyzed gas–rock–water systems, in the modeled period of 20,000 years, the minerals able to trap carbon dioxide are calcite and dolomite. Mineral-trapping capacity of carbon dioxide, calculated for the sandstones considered, equals to 9.19 and 12.0 kg per one cubic meter of the formation.
