Abstract
Foaming formulations and methods and systems for using foaming formulations are disclosed. Concentric tubing can be positioned in a wellbore in a subterranean formation to position an exit orifice of the concentric tubing at a target zone. A foaming formulation can be injected through a first flow path of the concentric tubing and a blowing gas can be injected through a second flow path of the concentric tubing to maintain separation until the foaming formulation and the blowing gas exit the concentric tubing. Mixing of the foaming formulation and the blowing gas at the target zone can generate foam.
