Artificial intelligence (AI) through deep learning offers new opportunities to solve complex problems such as structural geological modeling. In this work, we propose to use deep generative adversarial network (GAN) to generate unconditional geological models trained on a synthetic training dataset. The GAN is then used in a Bayesian context to find geological models that honor constraints such as drillholes. This approach makes it possible to simulate different geological models associated with different geological contexts. Finally, the proposed method offers better management of uncertainties.
