Carbon dioxide (CO2) from carbon capture and storage and direct air capture operations is often injected into deep geologic formations. These storage sites can be monitored for CO2 leakage. Monitoring can be done at both the surface and subsurface levels.[1] The dominant monitoring technique is seismic imaging, where vibrations are generated that propagate through the subsurface. The geologic structure can be imaged from the refracted/reflected waves.[1]
