The U.S. Deepwater Gulf of Mexico (DGOM) area that has some the most prolific oil reservoirs is still awaiting development a viable enhanced recovery (EOR) process. Without it, DGOM will remain severely untapped. Exorbitant well costs, in excess $200 million, preclude having extensive injection patterns, commonly used EOR design frameworks. Aside from even operationally waterflooding met with s...

– Experiments on foam drainage have so far only been performed in essentially one-dimensional flow geometries aligned with the direction of gravity. Here a foam-filled HeleShaw cell is used to examine pulsed drainage, which is the flow of a finite liquid volume, both along and perpendicular to the direction of gravity. An exact similarity solution to the generalized foam drainage equation exist...

Abstract The instability at the interface between two parallel flows of immiscible liquids through a uniform planar pore is studied by using linear stability analysis. A characteristic equation determines growth rate versus wavenumber, and conditions are determined. governed dimensionless group relating ratio gravity to interfacial tension. Interfacial tension has stabilizing effect resisting d...
