Alkyl Polyglucosides stabilized foam for gas controlling in high-temperature and high-salinity environments

Abstract APG can be employed as a promising foaming agent due to its largely independent of temperature and salinity. Aiming at the APGs foam, we conducted the experiments about adsorption behaviors, surface viscoelasticity, bulk foam properties and core flooding under conditions of high-temperature and -salinity. Our results demonstrated that APG (n = 10) foam presents a good foam performance and foam properties are highly depended on the surface viscoelasticity and are not completely determined by the adsorbing capacity at the interface of gas–water. In the porous media, an appropriate foam quality of APG foam is contributed to increase the foam strength and gas trapping.
