N2 - We investigate the potential of scattered seismic waves to remotely sense geological sequestration of CO 2 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 CO 2 sequestration, due to fluid substitution and mineral precipitation.
