Since the fluid velocity within the geothermal reservoirs created in the fractured rock can be relatively high and the characteristic sizes of the solid blocks of the rock, which constitute the fissured reservoir media, are relatively large, the high mean values of heat flow rates are typically attained within the stimulated region. In this situation the effect of thermal dispersion is an important factor that should be included into the mathematical model of the heat transport within the natural or artificially developed fissured geothermal reservoirs. Employing different... [Pg.652]

Fractures are important for fluid flow in oil, gas, and water production and geothermal processes. In such cases, the fluids are stored mainly in the matrix porosity but produced primarily using fracture permeability. Fractures penetrating impermeable shale layers create hydraulic conductivity and can develop a reservoir. Artificial fracturing (hydrofrac) can create new fractures or magnify existing fracture. On the other hand, fractures significantly reduce mechanical rock properties. [Pg.35]
