CA 2491004
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 disclosed, 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 of solids that may form from the use of neat foaming agent.
On décrit un nouvel agent de moussage à usage général présentant des applications comme agents moussants de fluide de forage ou comme tout agent moussant nécessaire dans une grande variété d'applications, ledit agent comprenant au moins un surfactant anionique, au moins un surfactant cationique, et des mélanges de ceux-ci et un ou plusieurs composés zwittérioniques. Un procédé d'utilisation de l'agent moussant dans une application de tube spiralé capillaire est également décrit. Les agents moussants peuvent également comprendre un additif pour augmenter les propriétés de l'agent moussant pour une application donnée. Un agent moussant dilué peut être utilisé pour réduire la chute de pression à travers le tube et empêcher la formation de solides susceptibles de se former à cause de l'utilisation de l'agent moussant pur.
