Parametrization of stochastic inputs using generative adversarial networks with application in geology

no code implementations7 Apr 2019 Shing Chan, Ahmed H. Elsheikh

The method is assessed in subsurface flow problems, where effective parametrization of underground properties such as permeability is important due to the high dimensionality and presence of high spatial correlations.

Exemplar-based synthesis of geology using kernel discrepancies and generative neural networks

no code implementations20 Sep 2018 Shing Chan, Ahmed H. Elsheikh

We synthesize new realizations such that the discrepancy in the patch distribution between the realizations and the exemplar image is minimized.

Parametric generation of conditional geological realizations using generative neural networks

1 code implementation13 Jul 2018 Shing Chan, Ahmed H. Elsheikh

This inference network is a neural network trained to sample a posterior distribution derived using a Bayesian formulation of the conditioning task.

Parametrization and generation of geological models with generative adversarial networks

1 code implementation5 Aug 2017 Shing Chan, Ahmed H. Elsheikh

One of the main challenges in the parametrization of geological models is the ability to capture complex geological structures often observed in the subsurface.
