摘要

A new general purpose foaming agent having application as drilling fluid foaming agents or as any foaming agent needed an a wide variety of applications is disclose d, where the agent includes at least one anionic surfactant, at least one cationic surfactant, and mixtures thereof and one or more zwitterionic compounds. A method for using the foaming agent in capillary coiled tubing application is also disclosed. The foaming agents can also include additive to augment the properties of the foaming agent for a given application. A diluted foaming agent can be used to decrease the pressure drop through the tubing and to prevent the formation o f solids that may form from the use of neat foaming agent.
