Experimental Study: Foam Generation and Propagation in Flow Across a Permeability Contrast

Foam is useful as an enhanced oil recovery method to reduce gas mobility and prevent gravity override to improve sweep efficiency. Foam is generated in porous media when exceeding a critical velocity and pressure gradient, that usually occur near to an injection well. There is the uncertainty of foam generation in the low-pressure gradient and...

Upscaling polymer flooding: Developing a workflow based on particle swarm optimization

In this research a workflow for upscaling polymer flooding is developed. The workflow generates pseudorelative permeabilities (pseudos) to represent flow behaviour affected by fine scale heterogeneities in a coarse grid. With this workflow, a better estimate of the difference in production from a polymer flood compared to a water flood can be...
