Prediction-Focused Subsurface Modeling: Investigating the Need for Accuracy in Flow-Based Inverse Modeling

Scheidt, Céline ; Renard, Philippe ; Caers, Jef

In: Mathematical Geosciences, 2015, vol. 47, no. 2, p. 173-191

The objective of most formulations of inverse modeling in the Earth Sciences is to estimate the model parameters given the observation data. In this paper, an additional element to these formulations is considered, namely, the prediction for which the models are built. An example of such modeling is the prediction of solute transport using geological models of the subsurface constrained to...
