“…The onset of the pending energy crisis and the recognition ofthe significant heat in the earth's crust prompted LANL to recognize that if artificial fractures could be created in areas of high heat flow, the earth's heat could be recovered by circulating water through these artificial fractures, and the concept of Hot Dry Rock was proposed (Robinson et al 1971), then further developed and patented.…”

(Dennis andPotter, 1974 PREFACEIn geology, the term "basement" generally refers to the crystalline rock that underlies the soils, gravels, and sedimentary formations that in most places constitute the uppermost layers of the earth's crust. Actually, however, the word is poorly defined since, with the exception of a few glassy materials such as obsidian, all rocks in fact are crystalline. Also, it covers a wide variety of rock types, including the metamorphic formations produced by the action of heat and pressure on such sedimentary rocks as sandstones and shales.In the present context, the meaning of the word is specialized further. Here it is taken to mean the igneous, plutonic, and metamorphic formations that-unless they have been fractured by earth movements or thermal effects-in general have very low permeability and free-water content; are likely to contain significant concentrations of naturally occurring unstable isotopes whose spontaneous decay produces heat; and through which heat is also conducted upward from the lower crust and mantle toward the earth's relatively cool outer surface. It is this general kind of rock that is most likely to exist in nature at usefully high temperatures and accessible depths in the earth's upper crust and to have permeability low enough to contain a pressurized-water circulation loop that can extract heat from the rock and transport it to the surface. Accordingly, basement rock so described has received primary attention in the Hot Dry Rock Geothermal Energy Program that is the subject of this report. There are, of course, other rock types that qualify as natural sources of thermal energy, but these are the subjects of other reports.This report describes the early history of the pioneer effort to develop a practical method of recovering useful energy from naturally heated rock in the earth's upper crust. It describes minor triumphs and disappointments and presents new evidence of the inherent perversity of nature, inanimate objects in general, much of mankind, and most bureaucracies. And it is undoubtedly biased by the fact that its author...

“…Three experiments, being conducted simul taneously (Kruger and Ramey, 1974), are providing data on mass transfer in porous media with tritiated water (HTO) as a tracer, heat transfer in microfractured rocks with needleprobe thermal conductivity measurements, and surface emanation porosity with natural radon measurements (Stoker and Kruger, 1975) , which may indicate the change in emanating power or porosity resulting from stimulation processes.
