Application of diffracted wave analysis to time-lapse seismic monitoring of CO2 geosequestration

Abstract

Successful implementation of carbon capture and sequestration technology requires monitoring techniques for tracking CO2 plume evolution in the subsurface and early leakage detection. Application of time-lapse seismic data for these purposes can often be challenging in low signal/noise ratio conditions. The research is focussed on developing a robust seismic imaging algorithm for CO2 geosequestration monitoring, based on diffracted waves analysis. The algorithm is tested on several datasets, including CO2CRC Otway project time-lapse seismic data.
