Geothermal systems are commonly investigated with numerical simulations, and these simulations are subject to uncertainties. In recent years, many methods have been developed to address the analysis of uncertainties in simulations. Several of these methods can directly be applied to the analysis of geothermal systems, but we often face specific additional problems, for example related to the consideration of boundary conditions, the complexity of coupled processes, and flow in fractured porous media.

In this session, we aim to provide a platform to discuss recent developments and applications of suitable methods from the areas of model calibration, inversion, stochastic modeling, optimization and subsequent analyses of uncertainty quantification with applications to the broad range of geothermal systems. Nonlinearities and the associated parameter sensitivities are in addition of specific interest, as well as approaches for history matching in engineered or operating systems. We are looking forward to your contributions to foster an active discussion on these relevant aspects related to numerical simulations of geothermal systems.
