Los Alamos Hot-Dry-Rock Project: Recent Results

, 1982
A new deeper reservoir is presently being investigated at the Laboratory's Fenton Hill Hot Dry Rock (HDR) site. The region surrounding the lower of two inclined boreholes, directionally-drilled to about 4 km in hot crystalline rock, has been pressurized ...

Analysis of thermal production effect of multi-horizontal U-shaped well

Case Studies in Thermal Engineering
The multi-horizontal section hot dry rock (HDR) heat extraction system is proposed for efficient deep geothermal resources mining in this study. The thermal-hydraulic numerical model of the multi-horizontal section geothermal exploitation system is set ...

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

Journal of Physics: Conference Series
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.

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.

Sizing of a hot dry rock reservoir from a hydraulic fracturing experiment [PDF]

, 1985
Hot dry rock (HDR) reservoirs do not lend themselves to the standard methods of reservoir sizing developed in the petroleum industry such as the buildup/drawdown test. In a HDR reservoir the reservoir is created by the injection of fluid. This process of

New quantitative characterizations of flow and heat transfer in hot dry rock fracture

Journal of Rock Mechanics and Geotechnical Engineering
The overall heat transfer coefficient (OHTC) of rock fractures is a fundamental parameter for characterizing the heat transfer behavior of rock fractures in hot dry rock (HDR) geothermal mining.

An estimate of the cost of electricity production from hot-dry rock [PDF]

, 1993
This paper gives an estimate of the cost to produce electricity from hot-dry rock (HDR). Employment of the energy in HDR for the production of electricity requires drilling multiple wells from the surface to the hot rock, connecting the wells through ...
