Experimental investigation of CO2-brine-calcite interactions under reservoir conditions

Deep geological formations such as saline aquifers and depleted oil and gas fields are potential sites for CO2 geological storage. The local host rock in these formations can have significant quantities of calcite present, such as in limestone or where carbonate formations have overlying chalk intervals. Therefore, the objective of this work is to understand how CO2-saturated brine interacts with calcite under reservoir conditions. Hydrothermal...
