Foam increases sweep efficiency during gas injection in enhanced oil recovery processes. Surfactant alternating gas (SAG) is the preferred method to inject foam for both operational and injectivity reasons. Dynamic SAG corefloods are unreliable for direct scaleup to the field because of core-scale artifacts. In this study, we report fit and...

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 is able to increase gas’s sweep efficiency in Enhanced-Oil-Recovery applications. A surfactant-alternating-gas, or SAG, process is usually preferred for placing foam in the reservoir. During a SAG process, foam is generated away from the wellbore, offering both good injectivity and good mobility control at the leading edge of the foam bank....

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...
