Temperature effects on anionic/nonionic surfactant mixture and silica nanofluid dispersion for foam-EOR
Foam-assisted gas has been widely employed in enhanced oil recovery (EOR) by improving the volumetric sweep efficiency gas mobility of injected gas. However, the major obstacle of foam-assisted gas EOR is maintaining foam lamellae�s stability, especially in harsh reservoir conditions. As mentioned...
