Abstract

The hydrocarbon industry has dominated and led the development of downhole measurements and subsurface data collection. Throughout the continuous development of borehole geophysical methods and technologies, many of the sophisticated techniques developed have been focused on the evaluation of hydrocarbon bearing formations. However, there is a lack of focus on the rapidly growing need for techniques applicable to geothermal energy development. Many questions still need to be satisfied in adapting these measurements to the special needs of the geothermal industry. What is really needed for the geothermal energy development? What is absolutely essential to know about the subsurface? What are desirable downhole measurements?
