Abstract
We present a stochastic approach for estimating geothermal and hydraulic properties in a medium-enthalpy geothermal reservoir Southern Tuscany (Italy) on a regional scale. The approach combines interpretations of different types of geophysical field data geophysical and geological borehole logs and laboratory data with hydro-geothermal numerical simulations. Special attention is paid to quantifying the uncertainties of the derived 3D model. For estimating model uncertainties, distribution functions are derived or estimated for all geophysical properties involved based on borehole measurements, careful seismic velocity analysis and forward modeling.
