THE USE OF CHEMISTRY OF DEEP AQUIFERS IN THE POLISH LOWLANDS AS AN INDICATOR OF THEIR SUITABILITY FOR STORAGE OF CARBON DIOXIDE IN THE PRELIMINARY STUDIES
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2012, Vol 448, Issue 448
Abstract
A detailed study of site hydrogeology, hydraulic properties of formations, and identification of all potential leakage pathways must be performed during an analysis of suitability for carbon dioxide storage. Prior these investigations, a preliminary hydrogeochemical analysis might be carried out, based on investigations of the geochemical maturity of groundwater and isolation of aquifers, measured by TDS, Na/Cl and Cl/Br ratios. Six types of groundwater, according to the degree of geochemical maturity and isolation, have been identified in the Polish Lowlands; from the modern freshwaters that contact with meteoric waters (types 1 and 2), to the oldest, stagnant, highly mineralized brines (types 5 and 6). The Carboniferous, Permian, Triassic and Jurassic aquifers, between 290 and 4907 m depth, contain waters of 0.5–458.4 g/l TDS. The geochemical maturity of waters depends on the depth, presence of impermeable caprock, distance from the outcrops and presence of faults and fractures. The waters in the Jurassic reservoirs are of different types, from types 1 and 2, which are not suitable for CO[sub]2[/sub] storage, to types 3 and 4, which are more suitable. The Triassic reservoirs are mostly of types 4 and 6, which are more suitable for CO[sub]2[/sub] storage. The most suitable for CO[sub]2[/sub] storage are the Permian aquifers of types 4 to 6.
