AB - This study combines water and CO2 core flooding experiments on both homogeneous and heterogeneous sandstone samples at varying pressure states with simultaneous acquisition of ultrasonic acoustic measurements of P- and S- wave velocities and X-ray CT imaging. Experiments have been conducted at confining pressures of up to 12 MPa, with effective pressures up to 11 MPa. Ultrasonic acoustic measurements were conducted utilizing transducers which are optimized for the production of shear waves, placed in an axial direction along the core. X-ray CT images were acquired with a medical CT scanner. Boise and Nugget sandstones have been studied. Boise sandstone has high porosity and permeability and is homogeneous whilst the heterogeneous Nugget sandstone has lower porosity and permeability. In both samples a reduction in P- and S- wave velocity was observed during CO2 flooding versus during water flooding.
