Modelling the FluidFlower: Insights from Characterisation and Numerical Predictions

The FluidFlower International Benchmark Study is a unique chance to assess the uncertainties introduced by numerical modelling through comparison to high-quality experimental data. A complete description of how the experiment was modelled by CSIRO is presented here, from the simplified model of the tracer tests and subsequent inversion of the permeability data using the spatial tracer concentration, the rapid development of an open-source finite volume simulator capability, through to the final numerical predictions and the reporting of key metrics.
