Renewable energy exploration and development is currently enjoying new interest as the nation seeks to lessen its dependence on foreign oil sources. Geothermal energy is competitive in areas where high heat flow and crustal water circulation combine to provide a readily accessible resource. Nevada in particular has abundant potential for geothermal energy development. The effort at present with...

Efforts to characterize geothermal supply have long been focused on the aspect of power generation [Petty, et al., 1992], [Petty, et al., 2007], and [Augustine, et al., 2010]. This paper focuses on an approach to characterize the supply curve of hydrogeothermal energy that can be used for direct use in the United States. It aims to compensate for the absence of research on thermal uses and prov...

A brief summary of the importance of the electrical resistivity of rocks in geothermal exploration is given as well as some of its is main relationships with some of the characteristics of geothermal reservoirs. Special emphasis is on the resistivity of rocks in high temperature geothermal fields where the dominant factor is the hydrothermal mineral alteration and how it relates to temperature....

Background (Ba,Sr)SO4 solid-solutions range among the most important scaling minerals, not only in geothermal energy production, but generally in applications involving hydrothermal brines, e.g. including petroleum production [e.g. (Todd and Yuan 1990, 1992; Kühn et al. 1997)]. Besides the general difficulties related to scale formation, like blockage of pipes, related decrease of well producti...

The dynamical role of geothermal heating in abyssal circulation is reconsidered using three independent arguments. First, we show that a uniform geothermal heat flux close to the observed average (86.4mWm−2) supplies as much heat to near-bottom water as a diapycnal mixing rate of ∼10−4 m2 s−1 – the canonical value thought to be responsible for the magnitude of the present-day abyssal circulatio...

Understanding and predicting how global warming affects the structure and functioning of natural ecosystems is a key challenge of the 21st century. Isolated laboratory and field experiments testing global change hypotheses have been criticized for being too small-scale and overly simplistic, whereas surveys are inferential and often confound temperature with other drivers. Research that utilize...

Ziagos, J.P. and Blackwell, D.D., 1986. A model for the transient temperature effects of horizontal fluid flow in geothermal systems. J. Volcanol. Geotherm. Res., 27: 371-397. A characteristic temperature versus depth (T-D) profile is observed in various geothermal environments. Particular features of the T-D profile can be explained in terms of a simple time-dependent two-dimensional (x, z) hy...

Background After decades of research carried out in India by several government organizations, a decision has been taken to generate 1000 MW of electricity using geothermal energy by 2022. Geothermal energy is perceived as a hidden potential in the earth’s crust. The USA, Indonesia, Philippines, Italy, Mexico and Iceland are the leading nations in utilizing this potential. Research efforts in I...
