Seismic and geoelectric modeling studies of parameters controlling CO2 geostorage in saline formations

► We model seismic and geoelectric sensitivities for monitoring CCS in saline aquifers. ► With CO2 saturation rise geoelectric anomalies increase higher than seismic ones. ► Seismic and geoelectric combination complement each others in quantifying CO2 saturations. ► Reservoir is mapped when dimensions are less than wavelengths and electrode spacings. ► Geoelectric resolution is strongly enhanced by a priori considering seismic results.
