AbstractBorehole geophysical methods are a key component of subsurface monitoring of geological CO2 storage sites as boreholes form a locus where geophysical measurements can be compared directly with the controlling geology. Borehole seismic methods including intra-well, crosswell and surface-to-borehole acquisition are useful for site characterization, surface seismic calibration, 2D/3D time-lapse imaging and microseismic monitoring. Here, we review the most common applications of borehole seismic methods in the context of storage monitoring and consider the role that detailed geophysical simulations can play in answering questions that arise when designing monitoring plans. Case study examples are included from the multitude of CO2 monitoring projects that have demonstrated the utility of borehole seismic methods for this purpose over the last 20 years.
Summary(Plain Language Summary, not published)
Geological CO2 storage sites require monitoring to ensure safe and secure long-term storage of CO2. Geophysical seismic methods that use boreholes for this purpose are important as the seismic images of the storage reservoir can be compared directly with the associated rock formations at the borehole. We review the most common applications of borehole seismic methods with case studies from the last 20 years.
