“…Synthetic polymers and biopolymers have shown sterling properties for stabilizing foam [ 88 , 89 ]. Wang et al [ 90 ] examined the influence of HPAM on alpha olefin sulfonate (AOS) foam stability. The biggest foam volume and best foam stability were obtained at 0.1 wt.%.…”

“…Finally, some areas of contention exist among researchers on the foaming properties of polymer-stabilized foam, which need to be clarified. For example, some research stated that the molecular weight of foam has little or no influence on the foaming capability, while others opined that the increase in molecular weight of the polymer causes high foam stability [ 90 , 95 ].…”

Polymers play a significant role in enhanced oil recovery (EOR) due to their viscoelastic properties and macromolecular structure. Herein, the mechanisms of the application of polymeric materials for enhanced oil recovery are elucidated. Subsequently, the polymer types used for EOR, namely synthetic polymers and natural polymers (biopolymers), and their properties are discussed. Moreover, the numerous applications for EOR such as polymer flooding, polymer foam flooding, alkali–polymer flooding, surfactant–polymer flooding, alkali–surfactant–polymer flooding, and polymeric nanofluid flooding are appraised and evaluated. Most of the polymers exhibit pseudoplastic behavior in the presence of shear forces. The biopolymers exhibit better salt tolerance and thermal stability but are susceptible to plugging and biodegradation. As for associative synthetic polyacrylamide, several complexities are involved in unlocking its full potential. Hence, hydrolyzed polyacrylamide remains the most coveted polymer for field application of polymer floods. Finally, alkali–surfactant–polymer flooding shows good efficiency at pilot and field scales, while a recently devised polymeric nanofluid shows good potential for field application of polymer flooding for EOR.

A Review on Foam Stabilizers for Enhanced Oil Recovery

The application of foam in the upstream petroleum industry has gained significant interest in the past few years. Foam usage can mitigate challenges associated with the gas flooding; it simply reduces the gas’s mobility, which could significantly enhance the sweep efficiency. Foam is generated using CO2 or N2 and stabilized by different materials such as surfactants, nanoparticles, polymers, or a combination thereof. The success of foam injection mainly depends on the stability of the flowing foam; the harsh reservoir conditions is one of the major challenges in this regard. Historically, surfactants have been used to generate and stabilize foams. However, recently, nanoparticles have gained attention due to their higher adsorption energy at the gas–liquid interface. In this paper, foam stabilizers such as surfactants, nanoparticles, and polymers are reviewed. Relevant advantages/disadvantages of different foam stabilizers and associated challenges are also highlighted. The results obtained in previous studies are discussed, and conflicting findings are highlighted and critically analyzed. Field applications of CO2 foam are also discussed in this Review. There are only a few field trials using surfactant stabilized foam. However, nanoparticle stabilized foam has not been tested in the field.

Foam flooding is one of the enhanced oil recovery (EOR) methods. Stability of the produced foam plays a significant role in overall efficiency of foam flooding. Polymers can be added to foam solutions to improve foam stability and enhance its characteristics. In this study the feasibility of improving foam stability by polymer addition is investigated. Alkyl Ethoxy Sulfate (AES) surfactant as the anionic surfactant and Cetyl Trimethyl Ammonium Bromide (CTAB) as the cationic surfactant are used as the foaming agents. The effects of polymer addition on foam stability is determined by the addition of different concentrations (0-3000 ppm) of PHPA and xanthan to foam solution and finally foam stability as the time taken for 80% of the foam to collapse was determined accordingly. The experimental results showed that CTAB performed better than AES as the foaming agent. Foam stability was enhanced by the addition of both PHPA and xanthan to foam solutions. Xanthan was more compatible with formation brine and PHPA was more compatible with fresh water to enhance foam stability.
