Abstract:

This study introduces a novel surveillance approach for CO2 geological storage, deviating from regular time-lapse measurements. The proposed workflow utilizes attributes derived from flow simulator output to identify critical locations in space and time to be monitored with focused seismic monitoring to effectively reduce uncertainties. The method serves as a frequent, environmentally friendly “trigger monitoring” tool that can be integrated into Monitoring, Measurement, and Verification (MMV) planning. Each spot’s expected behaviour is known before measurement, adding transparency. This transparency, combined with higher monitoring frequency, can contribute to constructive discussions with regulators and enhance societal acceptability of CCS projects.
