Abstract

Using a multidisciplinary approach, the present study aims to understand the potential of a new and novel type of geothermal system for high temperature and electricity production: Crustal Fault Zones (CFZ). Due to an intensive multivariate dataset, the Pontgibaud fault zone emerges as an ideal case study for understanding the factors controlling fluid flow in a fault zone system. 2D and 3D numerical modelling, as well as field and laboratory data, made it possible to quantify this new geothermal resource.
