In dry samples,the pressure dependence of velocity is ascribed to the difference in pore structures. Velocities were also measured to map the movement of the injected CO2 within water-saturated samples during CO2 injection. In the water-saturated samples, velocity changes caused by the CO2 injection are typically on the order of 10%. A series of seismic tomography experiments are conducted on porous sandstone samples to demonstrate the use of cross-well seismic profiling for monitoring the migration of CO2 in geological sequestration projects. %K P-wave velocity %K sandstone %K pore structure %K monitoring %K carbon dioxide %K geological sequestration
