Xu, F. (author), Hajibeygi, H. (author), Sluys, Lambertus J. (author)In fractured geological formations, as a result of the in-situ stress changes, fractures can propagate or slide. This phenomenon can be efficiently modeled by the extended finite element method (XFEM) when there are only a few fractures present. However, geological reservoirs contain many fractures which can also cross and are densely...journal article 2023

Wang, Y. (author), Vuik, Cornelis (author), Hajibeygi, H. (author)CO2 injection into deep saline aquifers has shown to be a feasible option, as for their large storage capacity under safe operational conditions.

Wang, Y. (author), Vuik, Cornelis (author), Hajibeygi, H. (author)Natural or induced fractures are typically present in subsurface geological formations. Therefore, they need to be carefully studied for reliable estimation of the long-term carbon dioxide storage. Instinctively, flow-conductive fractures may undermine storage security as they increase the risk of CO2 leakage if they intersect the CO2 plume. In...journal article 2022
