Hot dry rock reservoir modelling
, 2018 Geothermal energy reserves are significantly underdeveloped resources, and field experiments have shown the energy produced from this resource is clean and sustainable. Deep geothermal resources represent one form of geothermal energy, and the most widely used, in terms of commercial viability, are the hot dry rock (HDR) geothermal reservoirs.

Geothermal resource distribution and prospects for development and utilization in China
Natural Gas Industry BChina is tectonically composed of a series of plates and orogenic belts and has been influenced by the Pacific and Indian plates since the Late Paleozoic, forming a regular distribution of Mesozoic and Cenozoic granites.

Hot-dry-rock energy: review of environmental aspects [PDF]
, 1981 The potential environmental and socioeconomic impacts of the production of energy contained in hot dry rock (HDR) is surveyed here. In general, careful siting and timing and routine control measures should be adequate to prevent significant environmental harm; sites of particular ecological or visual and recreational value, however, may require more ...

A thermal stress loading technique for large‐sized hot dry rock mechanical tests
Deep Underground Science and EngineeringTesting of large‐sized specimens is becoming increasingly important in deep underground rock mechanics and engineering. In traditional mechanical loading, stresses on large‐sized specimens are achieved by large host frames and hydraulic pumps, which ...
