Laboratory seismic monitoring of supercritical CO2 flooding in sandstone cores using the Split Hopkinson Resonant Bar technique with concurrent x-ray CT imaging

ESD’s Seiji Nakagawa led a team of investigators (including ESD’s Tim Kneafsey, Tom Daley, and Barry Freifeld) in conducting laboratory measurements of the seismic properties of sandstones during supercritical CO2 injection. Accurate estimation of CO2 saturation in a saline aquifer is essential for the monitoring of supercritical CO2 injected for geological sequestration.
