Geothermal reservoirs and hot dry rock systems
1999Most geothermal reservoirs and hot dry rock (HDR) systems are located in fractured low porosity geological formations. In such settings, fractures provide conduits for fluid flow through such rocks. Therefore fractures, either natural or those artificially created, are important for the successful operation of geothermal reservoirs and HDR systems.

Physics of Fluids
A deeper understanding of interaction dynamics between hydraulic and natural fractures remains essential, especially for finite-scale natural fractures. In this paper, a three-dimensional hydraulic fracturing model is developed by using the discrete lattice method, which can simulate meticulously the dynamic evolution of both hydraulic and natural ...

Recent progress and technical directions in drilling technology for hot dry rock geothermal systems
Sixth International Conference on Green Energy, Environment, and Sustainable Development (GEESD 2025)Hot dry rock (HDR) geothermal energy, with its abundant reserves and high-temperature, is important for achieving carbon neutrality. However, its utilization is constrained by inefficient drilling technologies caused by extreme thermomechanical ...

Geochemical research in relation to hot dry rock geothermal systems
Geothermics, 1987Abstract This paper summarises the discussion of the potential value of geochemistry in HDR technology. The applications of geochemistry are discussed in terms of the nature and origins of fluids in granitic systems and the mineralogy of the granite. The use of chemical species as reservoir diagnostic tools is also discussed.

COMPLETION OF HOT DRY ROCK GEOTHERMAL WELL SYSTEMS
Proceedings of SPE Annual Technical Conference and Exhibition, 1979Abstract In the hot dry rock (HDR) concept of extracting geothermal energy, as developed by the Los Alamos Scientific Laboratory (LASL), a manmade geothermal reservoir is created by drilling a deep hole into relatively impermeable hot rocks, creating a large surface area for heat transfer by hydraulic fracturing ...
