Abstract

Foam is widely used in oil and gas recovery operations as a mobility control and profile correction agent. A brief list of foam applications includes acid diversion during matrix stimulation, gas blocking and enhanced oil recovery. This paper aims to study the dynamics of foam flooding assisted liquid displacement in a porous media. We report core-flood experiments performed using Bentheimer sandstone and N2 foam with the aid of X-ray computed tomography. A detailed description of CT images and quantification of local fluid saturation revealed that foam is formed in-situ and giving a mobility control. Furthermore, oil can be produced by a liquid slug induced by this strong immiscible foam front.
