Parameterization method of reservoir properties for ensemble-based data assimilation using intermediate latent space of StyleGAN

Excerpt

arXiv:2609.39626v1 Announce Type: new Abstract: Ensemble smoothers are the most successful and efficient techniques currently available for history matching. However, because these methods rely on Gaussian assumptions, their performance is severely degraded when the prior geology is described in terms of complex facies distributions (non-Gaussian). In this way, for these methods, we need to apply efficient parameterization techniques. Currently, the most efficient methods for performing paramete
