Abstract

Fracture patterns induced by supercritical-water fracturing show complex fracture networks with branched and isolated fractures. Such fracture patterns are expected to effectively increase permeability and significantly improve the heat exchange surface area. We clarify the mechanism of complex fracture induced by supercritical water using a coupled model and discuss the performance of the supercritical-water fracturing under geothermal environments. The numerical approaches to the coupled model are the pore-scale network method and finite element method with cohesive elements. Supercritical-water fracturing in granite at the laboratory scale was simulated and compared with the experimental results. The simulation results of fracture patterns are in good agreement with the experimental results.
