Crustal Conditions Favoring Convective Downward Migration of Fractures in Deep Hydrothermal Systems
Halldorsdottir, Sæunn; Berre, Inga; Keilegavlen, Eirik; Axelsson, Gudni (Journal article; Peer reviewed, 2023)Cooling magma plutons and intrusions are the heat sources for hydrothermal systems in volcanic settings. To explain system longevity and observed heat transfer at rates higher than those explained by pure conduction, the ... -
Hydro-mechanical simulation and analysis of induced seismicity for a hydraulic stimulation test at the Reykjanes geothermal field, Iceland
Keilegavlen, Eirik; Duboeuf, Laure; Dichiarante, Anna Maria; Halldorsdottir, Sæunn; Stefansson, Ivar; Naumann, Marcel; Guðnason, Egill Árni; Ágústsson, Kristján; Eggertsson, Guðjón Helgi; Oye, Volker; Berre, Inga (Journal article; Peer reviewed, 2021)The combination of seismic analysis with advanced physics-based simulation provides an opportunity to further understand injection-induced fault reactivation, including the hydro-mechanical interplay between different ... -
Numerical Modelling of Convection‑Driven Cooling, Deformation and Fracturing of Thermo‑Poroelastic Media
Stefansson, Ivar; Keilegavlen, Eirik; Halldorsdottir, Sæunn; Berre, Inga (Journal article; Peer reviewed, 2021)Convection-driven cooling in porous media influences thermo-poro-mechanical stresses, thereby causing deformation. These processes are strongly influenced by the presence of fractures, which dominate flow and heat transfer. ...
