A Streamline Based Lagrangain Method to Investigate Two-Phase Flow in Hydrocarbon Recovery

The study of miscible flow is an important topic in the field of petroleum science and engineering. The miscible displacement of hydrocarbon-like oil by a solvent such as carbon dioxide helps to enhance the recovery of the hydrocarbon. The use of CO₂ helps to reduce the viscosity of resident fluids like oil, In addition, the use of CO₂ would reduce its accumulation in the atmosphere to help a green environment. The production of hydrocarbons in the secondary or tertiary phase follows the mostly miscible flow. The Computational Fluid Dynamics (CFD) simulations can help with better understanding enchanch oil recovery in the two-phase flow system. The traditional simulations of such flow suffer numerical artifacts due to the appropriate methods. We present a generalized CFD model for studying the transient methodology for momentum transfer. We investigate an upscaling approach to resolve the small-scale features of miscible flow in a porous medium. A streamline-based Lagrangian model is developed to study the displacement of oil by CO₂ with sufficient accuracy and near-optimal computational cost.
