COMPLETION OF HOT DRY ROCK GEOTHERMAL WELL SYSTEMS

Proceedings of SPE Annual Technical Conference and Exhibition, 1979
Abstract 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 ...

The Future of Hot Dry Rock Geothermal Energy

2012
As detailed in preceding chapters, the technical feasibility of HDR geothermal energy was clearly demonstrated at Fenton Hill, with the testing of two separate confined reservoirs. The major task now in view is moving this revolutionary new technology to its appropriate place in the world’s energy supply mix.

Borehole measurements in the field of hot dry rock experiments

Geothermics, 1987
Abstract The logging group examined the value of different types of borehole logging in the context of HDR developments and considered the limitations of current techniques and the scope for further development. They recommended that the main development effort should concentrate on methods of fracture detection, both at the borehole wall and in the ...

The status of hot dry rock as an energy source

Energy, 1992
Abstract Hot dry rock (HDR) is a deeply buried crustal rock at a usefully high temperature. Current engineering designs plan to tap its heat by drilling a wellbore, fracturing or stimulating pre-existing joints around the wellbore, and directionally drilling another wellbore through the fracture network.

High-Temperature Slurry System for Dry Hot Rock

Chemistry and Technology of Fuels and Oils, 2017
Dry hot rock (DHR) is a kind of rock without water or steam lying 2-6 km underground with a temperature of 150-650°C. Domestic DHR at 3.5-7.5 km depth had a temperature of 150-250°C with a total energy of 6.3· 1024J, which was 1320 times the total energy consumption of China in 2010 assuming 2% of available exploration volume. Mixing of H2S, H2SO3, etc.

Hot Dry Rock Geothermal Resources in Southwestern China

2017
This chapter discusses Hot Dry Rock geothermal resources in southwest China and establishment of EGS system. Chinese terrestrial heat flow data amounts to 921 in 2001, which is the foundation assessing HDR geothermal resource. The highest heat flow values widely appeared in the Tibetan Plateau.
