About the Author
Prof. Aniko N. Toth is an internationally known expert on geothermal energy. A regularly featured speaker at the Stanford Geothermal Workshop over the past 9 years, she was also a 2011-2012 Fulbright Scholar at the Colorado School of Mines. She is currently leading several European Union projects to develop graduate-level degree programs in geothermal energy. Because of Prof. Toth's extensive experience in geothermal heat recovery, primarily dealing with Hungarian direct-use applications, the Hungarian government asked her to conduct a comprehensive survey of the nation's geothermal resources - the first of its kind in Hungary. Prof. Toth's international reputation as a geothermal-energy researcher is such that she was selected to teach a summer course at the University of Colorado in 2014, 2015 and again in 2016. Prof. Toth's research currently focuses on devising models to match various kinds of reservoir responses. These "inverse problems" seek the values of unknown reservoir parameters by inference rather than by direct measurement. Her specific interests are geothermal heat and flow transfer through porous materials, fractures, geothermal reservoirs, geothermal and CH wells, and geothermal surface facilities. Elemer Bobok is Professor Emeritus of Petroleum Geology and Engineering at the University of Miskolc in Hungary. For more than forty years, his scientific rigor and practical experience has prepared numerous Hungarian and international students for their doctorate degrees, and helped them find success later on as professors and field engineers.Recognized as an international expert on flow dynamics for the oil and gas industry, Prof. Bobok has more than 200 international publications to his credit. His classic 1993 Elsevier publication Fluid Mechanics for Petroleum Engineers, also available as an e-book, was written primarily to provide petroleum engineers with a systematic analytical approach to solving fluid-flow problems. In the years since this book first appeared, many geologists, hydrologists, mining-, mechanical- and civil engineers have also benefited from consulting this valuable resource.
