Foam is utilized in enhanced oil recovery and CO<sub>2</sub> sequestration. Surfactant-alternating-gas (SAG) is a preferred approach for placing foam into reservoirs, due to it enhances gas injection and minimizes corrosion in facilities. Our previous studies with similar permeability cores show that during SAG injection, several banks occupy...

Aqueous foam is a dispersion of gas in liquid, where the liquid acts as the continuous phase and the gas is separated by thin liquid films stabilized by a surfactant. Foam injection is a widely used technique in various applications, including CO2 sequestration, enhanced oil recovery, soil remediation, etc. Surfactant-alternating-gas (SAG) is a...

Surfactant-alternating-gas (SAG) is a preferred method of foam injection, which is a promising means of enhanced oil recovery. Liquid injectivity in a SAG process is commonly problematic. Our previous studies suggest that the liquid injectivity can be better than expected due to the existence of a collapsed-foam region formed during the gas...

Surfactant-alternating-gas (SAG) is a favored method of foam injection, which has been proved as an efficient way for enhancing oil recovery. However, foam flow is extremely complicated, and there are still unsolved problems for foam application. One is liquid injectivity. Our previous studies suggest that the injectivity in a SAG process is...

Foam increases sweep efficiency during gas injection in enhanced oil recovery (EOR)<br/>processes by reducing gas mobility. In fact, foam is the only EOR technology that is<br/>able to fight against both gravity segregation and geological heterogeneity. Surfactant Alternating Gas, or SAG, is the preferred method to place foam into the reservoir...

Foam can improve sweep efficiency in gas-injection-enhanced oil recovery. Surfactant-alternating-gas (SAG) is a favored method of foam injection. Laboratory data indicate that foam can be non-Newtonian at low water fractional flow f<sub>w</sub>, and therefore during gas injection in a SAG process. We investigate the implications of this...

Scope: Surfactant-alternating-gas (SAG) is the preferred method of foam injection to improve sweep efficiency in enhanced-oil-recovery (EOR). Here, for the first time, fractional-flow theory is extended to include the shock for gas injection in the high-quality regime for radial flow in a non-Newtonian SAG process for shear-thinning and shear...

Chemical enhanced oil recovery (EOR) is relatively expensive due to the high cost of the injected chemicals such as surfactants. Excessive use of these chemicals leads to processes that are not economically feasible. Therefore, optimizing the volume of these injected chemicals is of extreme importance. We intend to maximize the long-term...
