An evaluation of brine acquifer for the CO2 sequestration using seismic inversion


Abstract
The CO2 sequestration into brine aquifer is considered as one of the most feasible methods. However, we must evaluate the target aquifer to conduct the simulation before the operation of injection starts. The depth of the target aquifers is not less than 800m, so that seismic reflection method is the most effective tools to investigate a geological structure of such a deep underground. In addition, the seismic method can provide with reservoir properties using seismic inversion with log analysis. Thus we have conducted preliminary study and evaluated a potential of brine aquifer as a CO2 reservoir.
