Experimentally determined rock-fluid interactions applicable to a natural hot-dry-rock geothermal system [PDF]

, 1981
The field program cnsists of experiments in which hot rock of low permeability is hydraulically fractured between two wellbores. Water is circulated from one well to the other through the fractured hot rock.

Kinetic characterisation of sandstone exposed to high temperature-water cooling cycle treatments under the impact loading: from the perspective of geohazard

Geohazard Mechanics
Enhanced Geothermal Systems (EGS) improve geothermal energy extraction but can rapidly cool high-temperature rocks, leading to internal fractures that weaken mechanical properties and pose risks such as well collapses and seismic events.

Mechanical Sealing Method for Laboratory-Scale Hydraulic Fracturing Tests of Granite Rocks Under High-Temperature and High-Pressure Conditions

Applied Sciences
Deep hot dry rock (HDR) geothermal energy is a widespread and sustainable renewable energy that could be extracted for the decarbonisation of electricity generation. Measurements are essential for hydraulic fracturing in HDR monitoring, which can be used

Future of hot dry rock geothermal energy systems [PDF]

, 1979
Where natural groundwater circulation does not exist, the obvious method of extracting heat from the earth's crust is to imitate nature by creating it. A means of doing so by hydraulic fracturing has been demonstrated.

Session 8: Hot Dry Rock Update

, 1983
In 1970, Los Alamos began an informal study of the possible usefulness of hot dry rock (HDR) energy systems based on circulation of water through hydraulic fractures connecting two wellbores drilled into hot crustal rock of low initial permeability and ...

Hot dry rock fracture propagation and reservoir characterization [PDF]

, 1988
North America's largest hydraulic fracturing opeations have been conducted at Fenton hill, New mexico to creae hot dry rock geothermal reservoirs. Microearthquakes induced by these fracturing operations were measured with geophones.

Research progress on mechanisms of induced seismicity and microseismicity during full life cycle of EGS

Meitan xuebao
Enhanced geothermal systems (EGS) offer a practical route for extracting heat from hot dry rock, yet their operation can be accompanied by seismicity or microseismicity during hydraulic stimulation, after shut-in, and throughout later circulation.

Study on the evolution of mechanical properties of hot dry rocks after supercritical CO2 injection

Geothermal Energy
Characterizing the evolution of mechanical properties of hot dry rock (HDR) after supercritical CO2 (CO2(sc)) injection is crucial for assessing the heat extraction rate and reservoir security of CO2 based enhanced geothermal systems. This study designed
