A series of modelling tools have been developed for fractured media, where the problem of connectivity is the major mechanism governing flow, and mass or heat transport. These are Boolean models, where randomly distributed fractures are generated in space. Flow and transport properties are then distributed at a local scale for calculating global hydraulic and dispersive behaviour. Ensembles of...
The paper presents the results of heat extraction modelling for a prototype Hot Dry Rock (HDR) system at the Soultz-Sous-Forets site, France. The significant data from the 1993 experimental HDR programme at the Soultz site are summarized. Geological field evidence indicates that two major fault structures are superimposed on the four natural fracture sets used in the fracture network model. The...
