Seismic Attenuation and Dispersion caused by CO2-EOR related Flood

Abstract

CO2 mixing with liquids in rock reduces seismic velocities and increases attenuation. Understanding the frequency dependence of velocity and elastic moduli can aid in monitoring EOR and CO2 sequestration. This study reports measurements of dynamic elastic properties on a rock sample from the Gullfaks field using the unique low frequency apparatus at Colorado School of Mines. The measurements quantify the velocity dispersion and attenuation caused by CO2 flooding and displacements in the oil saturated rock.
