Liquid nitrogen pre-injection assisted fracturing in hot dry rock reservoirs

The Physics of Fluids
Hot dry rock (HDR) is one of the clean geothermal energy sources to develop. Geothermal energy extraction from HDR targets depths shallower than 5 km and temperatures up to 400 °C.

Semi-analytical model for heat transfer of supercritical CO₂ in parallel-fractured hot dry rock (HDR) reservoirs

Heat transfer is the critical process controlling the performance of heat extraction from hot dry rock (HDR) involved in enhanced geothermal systems (EGS). To facilitate the exploitation of EGS, this paper establishes a semi-analytical model for the flow and heat transfer of heat-carrying fluid in a parallel-fractured HDR reservoir.
