A deployment strategy for effective geophysical remote sensing of CO2 sequestration: Final report

The report examines alternative geophysical methods to time-lapse seismic that might be deployed to monitor commercial volumes of stored CO2. It uses simple geological models for the South Perth and Gippsland basins to simulate the resolution of various techniques or combinations of techniques. Topics covered include lowering noise levels in data processing workflows, estimate noise in a time-lapse sense for shallow well receivers as well as ambient noise imaging for ocean bottom receivers. Whilst no alternative method or combination of methods appears to have the sensitivity to adequately replace a time-lapse seismic approach, the added information could greatly improve the resolution and sensitivity of time-lapse geophysical methods alone.
