The obtained results have shown that by engineering proper cement solutions, the risks of casing failure in geothermal wells can be minimized to sustainably harvesting green power from superhot geothermal reservoirs. 1. INTRODUCTION To answer the growing need for energy and at the same time fighting...

... productivity of an EGS is controlled by the temporal evolution of induced fractures in geothermal reservoirs because the fracture network is the path by which heat (resource) is extracted from the subsurface. Therefore, it is essential to monitor the variation in fracture network characteristics over time...
