Salazar Castillo, R.O. (author), Ter Haar, Sterre F. (author), Ponners, Christopher G. (author), Bos, Martijn (author), Rossen, W.R. (author) 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...
