... °C, applied pressure of 1 – 4 bar, and fixed fluid flowrate of 0.5 L/min. In this study, the presence of high saturates composition in the crude oil which at 45 – 75.8 % influence the foam stability of the fluids. This reflects the waxy types of crude oils with higher density properties of 0.8768...

... Abstract Foam injection is designed to reduce the effects of high reservoir heterogeneities and fluid viscosity contrasts during gas flooding, and hence, improve sweep efficiency. However, harsh reservoir conditions in the Middle Eastern reservoirs pose a serious problem to foam stability...

... stability. Foam effectiveness and stability depends on a number of factors and will typically diminish over time due to degradation as well as the foam-rock-oil interactions. In this study, the effect of crude oil on CO 2 -foam stability and mobility will be addressed. Two-phase flow emulsification test...

... potential to be a successful technique. However, the rapid degradation of foam at high temperature condition in the presence of light crude oil limits its application. Therefore, introduction of an additive to the surfactant is crucial to maintain foam stability. Nano-scale particle is a well-known material...
