Two-phase flow simulation in low-permeability heterogeneous reservoirs with a fully implicit scheme-based enriched physics-informed neural network

Two-phase flow simulation in low-permeability heterogeneous reservoirs is challenging because low-velocity non-Darcy flow, capillary pressure, fractures, and heterogeneity produce tightly coupled and highly nonlinear pressure–saturation equations. A Fully Implicit Scheme-based Enriched Physics-Informed Neural Network (...
