Different enhanced oil recovery (EOR) methods have been implemented in oil fields over the
past decades. Gas flooding is widely used, but its effectiveness is hindered by mobility …

This study investigates the potential of foam flooding for enhanced oil recovery in oil-wet
fractured systems under reservoir conditions. Two surfactants with distinct ionic properties …

In the coming decades, regarding the enormous demands of fossil fuels in numerous
industries, petroleum engineers try to find novel solutions to produced more oil volume and …

Deep fractured vuggy reservoirs are characterized by complex structures, harsh formation
conditions and strong heterogeneity. Accordingly, foam stability was first assessed under …

The novel enhanced oil recovery (EOR) technique combining the reduction of oil/water (o/w)
interfacial tensions (IFT) to ultralow values and generation of a foam drive for mobility control …

Accurate understanding and quantitative characterization of the three-dimensional (3D)
immiscible water–oil two-phase displacement process and of the factors that affect this …

Foam flooding is an effective enhanced oil recovery (EOR) technology and has been widely
applied in conventional reservoirs. However, its application in fractured low-permeability …

We present a CT coreflood study of foam, both pre-generated and generated in-situ,
displacing oil, as a function of oil type and saturation. Foam generation and propagation are …

In this study, effect of pore-throat structure on air-foam displacement performance in a low-
permeability reservoir has been experimentally examined. More specifically, porosity and …

Foam flooding is an effective tertiary recovery method for oil and gas reservoirs. However,
foam performance is very sensitive to the reservoir temperature and pressure. In this study …
