Volatile surfactant treatment for subterranean formations

摘要

A method of treating a treatment zone of a well, the method comprising: (A) forming a treatment fluid comprising: (i) a continuous gas phase comprising a gas; and (ii) a surfactant, wherein the surfactant has the following characteristics: (a) a normal boiling point less than 500 °F (260 °C) without significant thermal decomposition; and (b) providing a dynamic surface tension of less than about 40 dynes/cm for a 0.1 wt% solution, or having an HLB (Griffin) in the range of about 2 to about 20, or both; wherein the surfactant is dispersed in the gas; and (B) introducing the treatment fluid into the treatment zone.
