Abstract: Abstract We propose the use of CO 2 in push-pull well tests to improve geophysical identification and characterization of fractures and faults at enhanced geothermal system (EGS) sites. Using TOUGH2/ECO2N, we carried out numerical experiments… read more here.

DOI: 10.1109/access.2020.3010507
Abstract: Fast electromagnetic (EM) simulation of thin layers, such as geological fractures and faults, is still a challenge since the local mesh refinement near such structures dramatically increases the number of degrees of freedom (DoFs), thus… read more here.

DOI: 10.3390/en13236275
Abstract: Fractures and faults are critical elements affecting the geomechanical integrity of CO2 storage sites. In particular, the slip of fractures and faults may affect reservoir integrity and increase potential for breach, may be monitored via… read more here.
