| Abstract |
Understanding of the geothermal reservoir, especially characterization of the cracks that form a subsurface fracture network, is essential for design, creation and control of engineered Hot Dry Rock/Hot Wet Rock (HDR/HWR) systems. Prediction of the energy production and lifetime remains a fundamental unsolved problem. Two projects are now aimed at solving these problems. While funded by Japan's NEDO, they bring together researchers from France, Germany, Japan, Switzerland, United Kingdom, and the U.S. They are focusing upon interdisciplinary work between seismology, reservoir engineering and rock mechanics to develop the required new methods. |
