We investigate the potential of scattered seismic waves to remotely sense geological sequestration of CO2 in basalt. Numerical studies in horizontally layered models suggest that strong scattering quickly complicates the wave fields, but also provides a sensitive tool to monitor physical changes in and around the reservoir. These results go hand-in-hand with recent laboratory work and rock-physics modeling that has shown significant changes in the seismic properties of a reservoir undergoing CO2 sequestration, due to fluid substitution and mineral precipitation.
