Abstract:Sedimentary basins can contain close to 20% by volume of pore fluids commonly classified as brines. These fluids can become undersaturated with respect to calcite as a result of migration, dispersive mixing, or anthropogenic injection of CO2. This study measured calcite dissolution rates in geologically relevant Na-Ca-Mg-Cl synthetic brines (50-200 g L−1 TDS). The dissolution rate dependency on brine composition, pCO2 (0.1-1 bar), and temperature (25.0-82.5 °C) was modeled using the empirical rate equation
R=k(1-Ω)n
