Modeling of Liquid Injectivity in Surfactant-Alternating-Gas Foam Enhanced Oil Recovery

An Experimental Study of Surfactant Alternating CO2 Injection for Enhanced Oil Recovery of Carbonated Reservoir

Core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating CO2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. The core samples were provided from a low permeability mixed wet oil reservoir at 156 °F and 1900 psia. In addition, very few studies of surfactant adsorption on car...

Theory of Three-phase Flow Applied to Water-alternating-gas Enhanced Oil Recovery

Surfactant Stabilized Nanoemulsion: Characterization and Application in Enhanced Oil Recovery

Nanoemulsions are a class of emulsions with a droplet size in the range of 50–500 nm and have attracted a great deal of attention in recent years because it is unique characteristics. The physicochemical properties of nanoemulsion suggests that it can be successfully used to recover the residual oil which is trapped in the fine pore of reservoir rock by capillary forces after primary and second...

Fractional-Flow Models for Foam Enhanced Oil Recovery

George E. P. Box wrote, "All models are false, but some models are useful." In that spirit, we examine fractionalflow models for foam enhanced oil recovery (EOR). This approach has long fascinated practitioners by transforming a physics problem first into a mathematics problem and then into a geometry puzzle. This approach, sometimes called the method of characteristics (MOC), makes many seriou...
