Enhancing Immiscible Fluid Mobilization in Porous Media Using Solute Deposition induced Permeability Control

Secondary imbibition is the process by which a wetting fluid displaces a non-wetting fluid in a partially saturated porous medium. Researchers at Princeton University have developed a novel process for mobilizing an immiscible fluid in a porous medium. An increase in the viscous pressure drop across trapped immiscible fluids in a porous medium can be...
