An Overview of the Present Stability and Performance of EOR-Foam

Abstract

Foam flooding technique, commonly known as foam assisted water alternating gas method (FAWAG)

Recovery of Crude Oil by Chemical Flooding Method using SDS and Gum Arabic Mixtures

“…One of the methods in enhanced oil recovery, EOR is surfactant flooding method employed to recover part of the residual oil left behind by water flooding. Surfactant flooding has been around for more than four decades and several reviews have been reported with the recent ones on surfactant flooding 1 , foam assisted 2 and nanotechnology for EOR 3 . Surfactants are special compounds that combine hydrophobic and hydrophilic molecules that constitute stable configuration in water and crude oil interfaces.…”

“…The use of surfactant in the oil recovery is well documented [1][2][3] . However, several works reported different result by using surfactant and polymer.…”

Investigation on the Stability of Janus SiO2-n Nanoparticle-Assisted Nonionic Surfactant-Stabilized Foam and Its Application in Enhanced Oil Recovery

“…Therefore, the oil resistance of the foam is evaluated via recording its volume decay under the impact of crude oil (Figure ). The crude oil can easily enter the foam film, resulting in the fabrication of the hydrophobic bridge among neighboring foam bubbles and high disjoint pressure, which directly leads to the rapid rupture of foam bubbles. − Then, the PMIE-stabilized foam almost completely disappears at 30 min, whereas the PMIE–JS n -stabilized foam, especially the PMIE–JS3 system, displays remarkable oil resistance with the remaining relative foam volume of about 35% at even 500 min, which should be attributed to the highly improved intensity of the foam film by the irreversibly adsorbed JS3 NPs.…”
