... ; Panahi, 2004 ; Le et al., 2008 ). The need for mobility control during CO 2 flooding has led to the study of foam processes, which involves the injection of CO 2 together with an aqueous solution of a CO 2 -foaming agent ( Chang and Grigg, 1999 ). CO 2 has a very low viscosity in comparison...

Abstract Although our primary interest in studying the technique of mobility control by foaming agents was for steam injection processes, this method seems to offer excellent prospects of improving oil recovery efficiency in any type of gas drive process. Laboratory studies showed that gravity...

.... In this process foam performs the role of a mobility control agent. By FAWAG process, reducing gas mobility can be achieved by creating more resistance to gas flow since gas bubbles are surrounded in foam by lamella. Oil displacement by foam is strongly dependent on reservoir temperature, pressure and crude oil...

... Placement. A considerable volume of theoretical, laboratory, and field work has been performed to evaluate the use of foams as mobility-control agents during steam and high-pressure gas floods (see Refs. 2-69 in Ref. 2). Much less work has been done to evaluate the use of foams as blocking agents...
