Title (EN) COMPOSITION AND METHOD FOR ENHANCED OIL RECOVERY FROM SUBTERRANEAN DEPOSIT
(FR) COMPOSITION ET PROCÉDÉ POUR RÉCUPÉRATION AMÉLIORÉE DE PÉTROLE À PARTIR D'UN DÉPÔT SOUTERRAIN
Abstract:
(EN) The present invention relates to a composition for enhanced oil recovery comprising a) at least one alkali metal dialkylbenzene sulfonate, b) at least one alkyl diphenyl ether disulfonate, c) at least one polyacrylamide selected from (c1) a partially hydrolyzed polyacrylamide, (c2) a sulfonated polyacrylamide and (c3) a sulfonated partially hydrolyzed polyacrylamide, d) at least one alkaline agent selected from sodium metaborate, sodium hydroxide, sodium tetraborate or sodium carbonate,and e) water. The present invention also relates to a method of enhanced oil recovery in which said composition is used.
(FR) La présente invention concerne une composition pour la récupération améliorée de pétrole comprenant a) au moins un dialkylbenzènesulfonate de métal alcalin, b) au moins un (éther diphénylique)disulfonate d'alkyle, c) au moins un polyacrylamide choisi parmi (c1) un polyacrylamide partiellement hydrolysé, (c2) un polyacrylamide sulfoné et (c3) un polyacrylamide partiellement hydrolysé sulfoné, d) au moins un agent alcalin choisi parmi le métaborate de sodium, l'hydroxyde de sodium, le tétraborate de sodium ou le carbonate de sodium, et e) de l'eau. La présente invention concerne en outre un procédé de récupération améliorée de pétrole dans lequel ladite composition est utilisée.
