... The in situ generation of foam is one of the methods that has been tried to overcome the gas mobility challenges and improve the volumetric sweep efficiency ( Kovscek and Radke 1994 ). The foam can be defined as a dispersion of gas (discontinuous) in liquid phase (continuous). By increasing...

... Abstract The steam-foam process is an Enhanced Oil Recovery (EOR) method which aims to improve the performance of a traditional steam drive by using a foaming surfactant. A Canadian thermal project under development in NW Alberta, which will use steam drive to recover extra heavy oil from...

... In the subsurface applications, the generated foam should have a long lifetime to deliver the desired function. Depending on the purpose of the application, foam properties can be tuned. For example, when foam is used to mitigate the liquid loading problem in gas wells, generally it should...
