WP3.07 software by Guy Drijkoningen

As part of the PhD work done in this work package, software has been developed to address issues related to 3D geophysical monitoring of CO2 storage. The focus has been on the seismic and the EM technique. One PhD focusses on seismic wave propagation effects in partly saturated media, and software has been developed that simulates seismic responses for such media. As part of the CATO2 work, this PhD has developed a new effective model which turned out to give good results for weak-frame and/or highly permeable rocks where conventional effective models fail. The software developed determines responses using this new effective model, next to exact solutions and other effective models. The responses simulate fluid-pressure and stress measurements.
