Abstract
Émulsions gélifiées contenant (i) une phase externe formée d'une solution aqueuse de solvant hydrosoluble, d'un agent viscosifiant et, de manière facultative, d'un agent de fractionnement oxydatif et/ou acide; (ii) une phase interne composée d'un fluide organique dispersé. La solution aqueuse de solvant hydrosoluble constitue environ 15 à environ 50 pour cent en volume de l'émulsion gélifiée, et le fluide organique dispersé est présent dans l'émulsion gélifiée en une quantité correspondant à environ 50 à environ 85 pour cent en volume. Les émulsions gélifiées ont diverses applications, notamment, sans en exclure d'autres, des applications dans les champs pétrolifères, les pipelines et les installations de transformation.
