True-triaxial apparatus for simulation of hydraulically fractured multi-borehole hot dry rock reservoirs

摘要

Drilling and stimulation are instrumental tools for underground injection and extraction of fluids for geo-environmental applications (e.g., CO_2 geological sequestration) and energy extraction (e.g., oil, gas or geothermal energy production). These tools have been proven successful for both traditional high permeability reservoirs and unconventional low-permeability resources (e.g., shale-gas formations). However, current methods become increasingly challenging and unreliable when implemented in deeper, hotter and more difficult geological resources.
