Available in PDF, EPUB and Kindle. Book excerpt: The geothermal resources of the Earth are enormous. The resource is considered to be an environmentally friendly clean energy source that could significantly contribute to the reduction of GHG emissions when utilized for electrical power generation or direct heating applications. The source of geothermal energy is the continuous heat energy flux flowing from the interior of the Earth toward its surface. Geothermal energy resources vary geographically, depending on the depth and temperature of the resource, the rock chemical composition, and the abundance of ground water. This book is the result of contributions from several experts and researchers worldwide. The introductory chapter highlights the principles of geothermal power generation using LEGE-ORC technology and presents a summary of the following book chapters. Due to its important utilization and future prospects, various interesting topics of research related to geothermal energy explorations are covered in this book. It is hoped that the book will become a useful source of information and basis for extended research for researchers, academics, policy makers, and practitioners in the area of renewable geothermal energy explorations.

Available in PDF, EPUB and Kindle. Book excerpt: Geothermal energy is being explored as a supplement to traditional fossil fuel resources to meet growing energy demand and reduce carbon emissions. Geothermal energy plants harvest heat stored in the Earth0́9s subsurface by bringing high temperature fluids to the surface and generating steam to produce electricity. Development of geothermal resources is often inhibited by large upfront risk and expense. Successful mitigation of those costs and risks begins with efficient characterization of the resource before development. A typically successful geothermal reservoir consists of a fractured reservoir that conducts hydrothermal fluids and a cap rock seal to limit convective heat loss through fluid leakage. The controls on the system include the density and orientation of fractures, mechanical rock properties, and the local stress field acting on those rocks. The research presented in this dissertation utilizes diverse data sets to characterize core, wireline borehole logs, and laboratory data to describe the distribution of fractures, rock properties, and the orientation and magnitude of stresses acting on the borehole. The research demonstrates there is a potential resource in the region and describes the controls on the vertical extent of the hydrothermal fluids. The distribution of fractures is controlled by the distribution of elastic rock properties and rock strength. A cap rock seal is present that limits hydrothermal fluid loss from a fractured artesian reservoir at 1,745 m (5,726 ft). In addition to characterization of the resource, this research demonstrates that an equivalent characterization can be used in future exploration wells without the expense and risk of collecting core. It also demonstrates that multiple methods of analysis can be utilized simultaneously when some data are not available. Data collection from deep wellbores involves risk and data loss or tool failure is a possibility. In these cases, our methods show that successful characterization is still possible, saving time and money, and minimizing the financial risk of exploration

Available in PDF, EPUB and Kindle. Book excerpt: The book provides the geoscientific context, that arises in gravimetric/magnetometric exploration. It essentially uses mathematics as a key technology for modeling issues on the basis of analysis and interpretation according to dense and precise gravitational/magnetic measurements. It is dedicated to surface and deep geology with potential data primarily of terrestrial origin. The book spans the interdisciplinary arc from geoengineering, especially geodesy, via geophysics to geomathematics and geology, and back again. It presents the recently published pioneering and groundbreaking multiscale mollifier methodologies realizing the bridging transfer from gravitational/magnetic measurements to approximative/numerical mollifier wavelet decorrelations with novel geologic prospects and layer-structure determination as outcome. Using the specific example of the German Saarland region, new important fields of application, especially for areas with mining-related cavities, will be opened up and subjected to an in-depth geologic detection.

Available in PDF, EPUB and Kindle. Book excerpt: Surface geophysical techniques are readily adaptable to exploration for and evaluation of geothermal reservoirs because existing equipment and interpretive models can be used. In contrast, the application of borehole geophysics for these same purposes requires the development of equipment to operate dependably in the very hostile environment of some geothermal wells. After equipment ahs been developed and tested, its response must be calibrated with respect to required parameters such as lithology and porosity. This is difficult in geologic environments where there is practically no experience in well-log interpretation. The desired final products are reliable data to guide exploration for geothermal systems, and to aid in reservoir evaluation, modeling, and development, in the ways in which well logs are routinely used in the petroleum industry. Researchers in geothermal exploration are still some years from achieving the level of application already attained in petroleum exploration and development. This deficiency is receiving some attention from the U.S. Energy Research and Development Agency (ERDA) and the U.S. Geological Survey. The two agencies cosponsored a workshop on Geophysical Measurements in Geothermal Wells in September 1975 (Baker, Baker, and Hughen, 1975). Sandia Laboratories had previously summarized the state-of-the-art in a report on "Well-Logging Technology and Geothermal Applications" (Baker, Campbell, and Hughen, 1975). For several years the U.S. Geological Survey has had a research program to develop logging instrumentation and log-interpretation techniques for geothermal applications. This summary describes some of the results of that research effort. 3 figs., 7 refs.
