(EN) POLYMER-SURFACTANT COMPOSITIONS FOR ENHANCED OIL RECOVERY PROCESS
(FR) COMPOSITIONS DE POLYMÈRE-TENSIOACTIF POUR UN PROCESSUS DE RÉCUPÉRATION ASSISTÉE DU PÉTROLE
Abstract
(EN) The present invention relates to a composition for an enhanced oil recovery process, said composition comprising (a) one or more anionic cocogem surfactants; b) one or more surfactants based on nonionic vegetable fatty acids (or their synthetic analogues); c) optionally one or more, preferably commercially available, co-surfactants; d) optionally one or more agents with phase transfer property, preferably an alcohol; and e) polyacrylamide as a flow modifier.
(FR) La présente invention concerne une composition pour un processus de récupération assistée du pétrole, ladite composition comprenant (a) un ou plusieurs tensioactifs anioniques géminés couplés à des contre-ions (cocogem); b) un ou plusieurs tensioactifs à base d'acides gras végétaux non ioniques (ou leurs analogues synthétiques); c) éventuellement un ou plusieurs co-tensioactifs, de préférence disponibles dans le commerce; d) éventuellement un ou plusieurs agents ayant une propriété de transfert de phase, de préférence un alcool; et e) un polyacrylamide en tant que modificateur de flux.
