To enhance solver performance and convergence, various strategies are employed, including inexact Newton methods, preconditioning techniques, multiscale solvers, and others. This internship explores the integration of a Neural Network (NN) single-cell method as a preconditioner for the non-linear system. The approach involves collecting simulation runtime data for each grid cell and feeding it into a pre-trained neural network to generate improved initial guesses prior to invoking the non-linear solver. This technique is inspired by the methodology presented in “Learning to Solve Parameterized Single-Cell Problems Offline to Expedite Reservoir Simulation” by Abdul-Akeem Olawoyin and Rami Younis (SPE-212175-MS, 2023). Responsibilities The intern will work closely with the Intersect innovation team to implement and test the pre-conditioner inside Intersect code. By the end of the internship the following technical deliverables are expected: Coupling pre-trained neural-network models with an existent commercial simulator to create a pre-conditioner for the non-linear solvers Testing different neural-network architectures to identify how to best solve this problem Propose an automatic method to export simulation data in a structured format, to be used as training data for the pre-conditioner This an innovation work, with an opportunity to publish it in a research journal.
