Abstract
Methods including providing a treatment fluid comprising: a gas; and a volatile surfactant dispersed in the gas, wherein the volatile surfactant has a normal boiling point of less than 260° C. without substantial thermal decomposition and a dynamic surface tension of less than about 40 dynes/cm for a 0.1% solution; and intermittently introducing the treatment fluid and an aqueous fluid into a treatment zone in a subterranean formation.

A method comprising:
- providing a treatment fluid comprising:
- a gas;
- and
- a volatile surfactant dispersed in the gas, wherein the volatile surfactant has a normal boiling point of less than 260° C. without substantial thermal decomposition and a dynamic surface tension of less than about 40 dynes/cm for a 0.1% solution;
- and
- intermittently introducing the treatment fluid and an aqueous fluid into a treatment zone in a subterranean formation, wherein the treatment fluid and the aqueous fluid are intermittently introduced into the treatment zone in the subterranean formation through an injection well, so as to displace hydrocarbons in the subterranean formation toward a production well.
