“…However, polyhedral foam is a mature structure with thinner lamella film, and it is termed as dry foam as the water content is less than the gas content. On the other hand, based on the bubble size, foam is classified as coarse and fine [25]. In general, a foam with a coarse texture contains numerous large bubbles, also known as low-density foam, whereas a foam with a fine texture, referred to as high-density foam, is composed of a substantial number of small bubbles.…”

Unconventional reservoirs, like shale gas, shale oil, tight gas sands, and coalbed methane deposits, pose unique challenges due to their low permeability, low porosity, and complex geological structures. These factors hinder the natural flow of hydrocarbons, necessitating advanced extraction techniques. Hydraulic fracturing is commonly used to increase permeability and enhance hydrocarbon recovery. However, this creates a challenge during gas injection due to significant permeability differences between fractures and matrix. Foam flooding is an innovative enhanced oil recovery method in heterogeneous systems. It reduces fracture transmissivity and improves matrix-fracture interactions, thus enhancing oil sweep efficiency. Yet, foam stability depends on the method of generation. Traditional foam pre-generation at the surface is ineffective in fractured systems as foam loses its properties during transport under high pressure and temperature. This study’s primary objective is to develop in-situ foam generation under reservoir conditions within fractured systems to enhance oil displacement. Achieving this involves optimizing factors like surfactant formulation, concentration, injection rate, and gas fraction. Additionally, the reservoir’s petrophysical properties like wettability, permeability, and mineral composition, are considered. As a result of these efforts, the foam generated in situ will possess the capability to adapt to prevailing conditions and boost hydrocarbon production from such reservoirs.

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.

“…However, foam is a thermodynamically unstable system; thus, it is crucial to select suitable surfactants or other foam stabilizers to increase its stability. As a result, foam mobility control capabilities are enhanced. , Polymers and nanoparticles can be added to the foaming solution to increase foam stability by lowering the pace at which liquid films discharge . This will enhance the strength of the liquid films and slow the diffusion of gas between bubbles .…”

CO 2 foam has been identified as having significant applications in carbon capture utilization and storage (CCUS). This is attributed to its proven capability to mitigate channeling during CO 2 injection effectively; meanwhile, the majority of injected CO 2 can be safely stored in reservoirs through geo-sequestration. However, the high injection pressure and poor foam stability severely affect the wide employment of CO 2 foam flooding. In this study, comprehensive investigations on a novel CO 2 -responsive foam (CRF) with desirable injectivity and noticeable longevity are presented. This novel foam system employs lauryl ether sulfate sodium (LES) and diethylenetriamine (DETA) as foaming agents, and it exhibits notable reversible CO 2responsive properties. This property enables the fluid to transit between low and high-viscosity states, enhancing foam injection performance and reducing the injection pressure. CRF is less detrimental to reservoirs compared to conventional polymer-enhanced foam (PEF) due to its ability to switch between gel-forming and gel-breaking phases using CO 2 /N 2 . In addition, rheological tests demonstrate that CRF exhibits superior high shear tolerance compared to PEF. Moreover, CRF shows greater stability and higher salt resistance compared to PEF. At a NaCl concentration of 5 × 10 4 mg/L, the half-life of CRF (152 min) was nearly 13 times longer than that of PEF (11 min). It is noted that CRF exhibits a higher resistance factor in high-permeability cores compared to low-permeability cores, indicating its outstanding capacity to block the channels and mitigate CO 2 breakthrough. The results of the enhanced oil recovery (EOR) experiments indicated that CRF is capable of displacing more oil than PEF in fractured cores with identical experimental conditions. It is believed that CRF may be applied as a viable CCUS technique and may enlighten investigations on novel CCUS strategies.
