Three‐Dimensional Thermoporoelastic Modeling of Hydrofracturing and Fluid Circulation in Hot Dry Rock

Geothermal energy, featured as a renewable low-carbon energy resource, exhibits great potential in mitigating global warming. However, efficient mining of geothermal from hot dry rock remains challenging due to the lack thermoporoelastic modeling approach that allows for integrated simulation hydrofracturing and fluid circulation, poor understanding mechanisms hydraulic stimulations. To conquer these challenges, we propose an advanced approach, which enables us deal with interplay between transport, heat transfer, deformation, three-dimensional fractures' growth interaction. Based on model, refined investigation is performed determine circulation processes, using data collected EGS Collab Experiment 1. This meso-scale testbed involves creating major fractures, accompanied by numerous secondary hydroshearing hydraulically connecting two horizontal wellbores build system. All were heavily instrumented monitoring devices, offering high-quality properly constrain geomechanical model. Our study provides insights into: (a) how responds propagating fractures strong stress shadowing long-term injection chilled water; (b) why parallel pattern distance much smaller than fracture dimension forms during multi-staged stimulations; (c) what are performance. Overall, this work not only contributes novel but advances our enhanced systems interconnected networks.
