Abstract: Abstract. Foam flooding is an effective enhanced oil recovery method for deep fractured vuggy carbonate reservoirs, but its application is limited by reservoir heterogeneity and foam stability. We systematically investigated ...

Abstract: In the late stage of exploiting heavy oil reservoirs with edge-bottom water, we are faced with problems such as high crude oil viscosity, channeling of bottom water, and rapid rise in water cut. To clarify the synergistic ...
