Compositional Modeling and EOR for Liquid Rich Shales

• Compositional Rate Transient Analysis
• EOR Potential


Driving Forces: Gravity, Darcy and Molecular Diffusion (mostly important but often overlooked). Combined effects (oil swelling effect, viscosity reduction and IFT reduction at Matrix and Fracture interface) were able to match the CO2 soaking experiments for Mid-Bakken. NGL may be better that CO2 for higher RF.
