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.

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.

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 ...

A history of hot dry rock geothermal energy systems
Journal of Volcanology and Geothermal Research, 1983Abstract This is a short history, so far as it can now be assembled, of early speculations and observations concerning the existence and origin of natural heat in the earth's crust; of some of the many methods proposed to extract and use it; and of recent investigations designed to develop and demonstrate such methods. It is probably only the preface

Monitoring and interpretation of seismic observations in hot dry rock geothermal energy systems
Geothermics, 1987Abstract As the value of microseismic monitoring during development of HDR reservoirs is already proven, the discussion group concentrated on assessing what further improvements might be made. They suggested improvements both to the receivers and to the methods of analysis, with particular reference to the derivation of different source mechanisms ...

Heat transfer by water flow in rock fractures and the application to hot dry rock geothermal systems
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1993The heat transfer coefficient is an important fundamental parameter which is essential for numerical analysis of hot dry geothermal energy extraction systems. An investigation on joint rock-water heat transfer was successfully carried out using a test set-up for hydro-thermo-mechanical experiments on rock samples from the Carnmenellis granite.

Hot dry rock geothermal systems: Geochemical applications of transient field experiments
Geothermics, 1987Abstract Although geochemical investigations of Hot Dry Rock geothermal reservoirs may be useful to both their short and long term operation, most applications of geochemistry require a knowledge of the chemical processes occurring in the various parts of the reservoir during circulation.

Abstract Monitoring microseismic emissions during fracturing and circulation experiments at the Camborne School of Mines 2 km deep hot dry rock geothermal project has been carried out over the past 5 yr. These microseismic locations provide the only information on the position of the stimulated region within the granite rock mass.
