Applications are being accepted for a fully funded PhD position at the University of Auckland on fracture and recharge modeling in superhot geothermal systems.
The Geothermal Institute at the University of Auckland in New Zealand is advertising a fully funded PhD position as part of the MBIE-funded DeepHeat Programme, delivered in collaboration with Earth Sciences New Zealand, focusing on modelling fracture-controlled permeability evolution and fluid flow in superhot geothermal systems.
This PhD will investigate how evolving fracture networks control fluid flow under injection and production conditions in superhot geothermal systems. The research will develop Discrete Fracture Network (DFN)-based models of fracture geometry and connectivity, coupled with geomechanical and thermo-hydro-mechanical (THM) processes governing fracture reactivation, propagation, and permeability evolution. It will integrate geological datasets, laboratory-derived behaviour, and reservoir-scale simulations to construct dynamically evolving fracture networks.
Key components include stochastic DFN generation, coupled THM–fracture modelling, and upscaling to continuum-reservoir properties using statistical and AI/ML approaches. The outcomes will support quantitative assessment of stress- and temperature-dependent permeability evolution, recharge efficiency, and permeability enhancement in superhot geothermal systems.
