Abstract Summary
The Rock Springs Uplift (RSU) located in southwest Wyoming USA is one of several sites across the country to be characterized for suitability for CO2 sequestration. Original rock cores of the Weber Sandstone and Madison Limestone formations from the RSU were prepared into 25-mm diameter rock samples. These samples were saturated with brine, aged with brine, and aged with CO2-rich brine. Laboratory triaxial experiments were performed at in-situ reservoir conditions. The effects of brine and COs on the mechanical behaviors of these samples are presented.
