...-logs. We employ a local Gauss-Newton (GN) optimizer that requires about half the number of simulations compared to equivalent gradient-based or serial optimizers. We approximate the sensitivity matrix by interpolating the resulting predictions with Duchon splines, i.e., radial basis functions, opposite...

... is essential to predict how much CO2 will be effectively trapped and how quickly this trapping occurs, and may necessitate fine grids in regions with steep gradients, while other areas with minor variations can be more coarsely resolved. Additionally, the expected gravity-driven convective mixing at field...

... variables from a high-dimensional space to a low-dimensional space, a linear transition network for predicting the evolution of state variables in the latent space, and a linear transition output for extending predictions to well output evolution over time. The E2CO framework is implemented using Proper...

... to use in history matching, optimization and uncertainty quantification workflows. We propose a novel machine learning architecture to auto-regressively predict state variables and well outputs of a reservoir for an ensemble of cases with varying well configurations. This new approach constructs a Graph...

... part of this paper therefore describes a new phase labeling method that uses both the critical temperature and saturation pressure predictions from the ML models to generate accurate labels. Results are presented for CO 2 rich fluids. We show that this ML approach can result in accurate labeling...

... Abstract Integrated reservoir studies for performance prediction and decision-making processes are computationally expensive. In this paper, we develop a novel linearization approach to reduce the computational burden of intensive reservoir simulation execution. We achieve this by introducing...
