Variations on bayesian optimization applied to numerical flow simulations
… problems. Despite its recent applications to numerical flow simulations, the efficiency of this method and its variants remains to be characterized in typical applications involving canonical flows. In this work, the efficiency of classical BO and alternative derivative-free methods is …

A New Analog for Numerical Flow Simulations Application to Direct Assessment of Reservoir Flow Performance Uncertainties
… a technique for directassessment of reservoir flow performance uncertainties, as compared to manytraditional, computationally expensive techniques such as Monte Carlo simulations. This is achieved via a single stochastic flow simulation that combineslocal geologic uncertainty with a new simple …

Jet mixing: the role of numerical flow visualization
… might be further enhanced by using the tool of numerical flow visualization to explore the results of numerical simulations and linear stability analysis. Because the results of preliminary numerical flow simulations were so topologically complex, linear stability analysis (LSA) was employed to …

Geometry-based finite volume methods for modelling transport on micro-CT images
… microscopic structure of reservoir rocks. Direct numerical flow simulations are a common approach to compute petrophysical properties of rocks by modelling fluid flow on rock micro-Computed Tomography (CT) images. However, they are computationally demanding and complicated to include additional …

Data-Driven Analytics for Oil and Gas Reservoir Production Forecasting
Detailed uncertainty analysis on numerical flow simulation models preserving a robust and reliable model of oil and gas reservoir is often deterministic, cumbersome and expensive (manpower and time consuming). Presence of a high-dimensional data space consisting of a large number of operational and …
