Los Alamos hot dry rock geothermal energy experiment

, 1976
Recent heat flow data indicates that about 95,000 sq. mi. in 13 western U.S. states is underlain, at a depth of 5 km (16,400 ft) by hot dry rock at temperatures above 290/sup 0/C (440/sup 0/F.).

Deterioration mechanisms of microscale mechanical properties in granite under ScCO2-water-rock interactions at high temperature and pressure

Meitan kexue jishu
To investigate the potential of supercritical carbon dioxide (ScCO2) as a heat-carrying fluid in Enhanced Geothermal Systems (EGS) and its impact on the mechanical properties of hot dry rock (HDR) reservoirs, this study conducted interaction experiments ...

Research and application of the cooling system for water-based drilling fluid in hot dry rock drilling

Journal of Physics: Conference Series
Abstract Hot dry rock (HDR) is a new source of environmentally friendly energy. However, during the former HDR drilling process without the cooling system, the high temperature resulted in the breakdown of drilling fluid and downhole drilling tools.

Hot dry rock geothermal heat extraction [PDF]

, 1979
A man-made geothermal reservoir has been created at a depth of 2.7 km in hot, dry granite by hydraulic fracturing. The system was completed by directionally drilling a second well in close proximity with the top of the vertical fracture.

Potential for hot-dry-rock geothermal resources: experimental results

, 1982
Hot dry rock (HDR) contains insufficient permeability and fluid for natural hydrothermal development, but water pumped in a circulation loop through a HDR reservoir (hydraulically fractured between two drill holes) is being tested and evaluated.
