Abstract

Basalt appears to have geochemical advantages as a reservoir for CO₂ sequestration, but it poses considerable challenges in terms of measurement, monitoring and verification with geophysical techniques. First, it is poorly understood how CO₂ injection in basalt influences the elastic properties. Second, layering of the basalt causes strong multiple scattering, complicating (surface) seismic imaging. To investigate the possibilities and limitations of time-lapse seismic monitoring of CO₂ injection in a layered basalt reservoir, we estimate wave speed variations due to fluid substitution, and perform numerical simulations of CO₂ reservoir monitoring.
