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 En...

An efficient surrogate-assisted hybrid optimization framework for polymer flooding management

<title>Abstract</title> Reservoir injection-production optimization plays a critical role in enhancing recovery in high-water-cut oilfields. While polymer flooding improves development efficiency by increasing viscosity and controlling fluid flow, its optimization faces several c...
