Title (EN) TREATING A FORMATION USING A FOAM FORMING COMPOSITION
(FR) TRAITEMENT DE FORMATION AU MOYEN D'UNE COMPOSITION MOUSSANTE
Abstract: front page image
(EN)A method of treating a formation around a wellbore extending from a hydrocarbon-bearing zone comprising the steps of interrupting production from the hydrocarbon-bearing zone; introducing into the hydrocarbon-bearing zone a foam forming composition comprising a surfactant-in-oil solution; and resuming production from the hydrocarbon-bearing zone.
(FR)L'invention concerne un procédé de traitement d'une formation située autour d'un puits de forage partant d'une zone contenant des hydrocarbures. Ce procédé consiste à interrompre la production à partir de cette zone, à y introduire une composition moussante contenant une solution tensioactif/huile, puis à reprendre la production à partir de ladite zone.
