“…The value of ∼0.8 refers to that convection should be also considered (P e > 0.5) in the process of heat transfer but not as the main driving force (P e > 1). Accordingly the components of conduction and convection mean approximately 10-10°C positive temperature difference at the top of the overpressured basement high (Vass, 2013). It should be noted that low permeability can cause reduced effect of convective heat transfer in several areas in the Pannonian Basin.…”

Fractured rock bodies are especially important in Hungary, where numerous hydrocarbon reservoirs and geothermal fields occur in the fractured crystalline basement of the Pannonian Basin. To simulate a 3D fracture network for both near well regions and at reservoir scale, a fractal geometry based DFN (discrete fracture network) modelling system (RepSim) was used. To perform numerical simulation of the geological-hydrogeological problem, in which the hydraulic interaction is investigated between porous and fractured rock bodies, a finite element modelling system called FeFlow was applied. Modelling results suggest that the protruding basement highs govern heat transfer and fluid flow like a "hydro-geothermal chimney" owing to their stratigraphic and structural position as well as favourable hydraulic and thermal conductivities. Thus such fractured basement highs are deemed prospective for further geothermal investigations.
