A problem associated with many gas injection projects is the inefficient gas utilization, poor
sweep efficiency, oil recovery due to viscous instabilities (channelling or fingering), and …

Foam assisted CO 2 enhanced oil recovery has attracted increasing attention of oil
companies and research institutions, mainly due to the potentially high benefit of foam on …

Surfactant-stabilized foams have been used in the past for vertical conformance and mobility
control in gas-enhanced oil recovery processes. Lack of stability of these foams often limits …

Foam-enhanced oil recovery (EOR) is poised to become one of the most promising tertiary
recovery techniques to keep up with the continuously increasing global energy demands …

Two significant problems, steam override and steam channeling, decrease the sweep
efficiency of steam to result in a lower oil recovery in heavy oil reservoirs. Thermal foam …

Foam assisted CO2 enhanced oil recovery has attracted increasing attention of oil
companies (operators and service companies) and research institutions mainly due to the …

A detailed laboratory study of nitrogen-foam propagation in natural sandstones in the
absence of oil is reported. The goal of this study was to elucidate further the mechanisms of …

Nanoparticles have gained attention for increasing the stability of surfactant-based foams
during CO2 foam-enhanced oil recovery (EOR) and CO2 storage. However, the behavior …

Enhanced oil recovery (EOR) from heavy oil reservoirs is challenging. High oil viscosity,
high mobility ratio, inadequate sweep, and reservoir heterogeneity adds more challenges …

Injecting foam into hydrocarbon reservoirs in order to transport the fluid is amongst the novel
methods for enhanced oil recovery (EOR). Stability of foam is the main challenge to …
