Data-Space Inversion with Ensemble Smoother

Mateus M. Lima, Alexandre A. Emerick, Carlos E. P. Ortiz

Reservoir engineers use large-scale numerical models to predict the production performance in oil and gas fields. However, these models are constructed based on scarce and often in…

Analysis of Geometric Selection of the Data-Error Covariance Inflation for ES-MDA

Alexandre A. Emerick

The ensemble smoother with multiple data assimilation (ES-MDA) is becoming a popular assisted history matching method. In its standard form, the method requires the specification o…

Numerical simulation of salt migration -- Large deformation in viscoelastic solid bodies

I-Shih Liu, Rolci Cipolatti, Mauro A. Rincon +1

We consider instability of a two layered solid body of a denser material on top of a lighter one. This problem is widely known to geoscientist in sediment-salt migration as salt di…
