Title
(EN) SURFACTANT FOR ENHANCED OIL RECOVERY
(FR) TENSIOACTIF POUR RÉCUPÉRATION AMÉLIORÉE DE PÉTROLE
Abstract
(EN)
The invention relates to a method of extracting hydrocarbons from a subterranean formation, comprising: - injecting a surfactant composition into the subterranean formation, and - collecting hydrocarbons displaced by the injected surfactant composition; wherein the surfactant composition comprises at least one surfactant compound of formula (I) wherein x is an integer from 0 to 3, R1, R2, R3, R4 and each R are independently a hydrogen atom or an alkyl group, each A is an alkylene group, and the total number of carbon atoms in the surfactant compound of formula (I) is from 10 to 21. The invention also relates to a composition comprising liquid or supercritical carbon dioxide and at least one surfactant compound of formula (I).
(FR)
L'invention concerne un procédé d'extraction d'hydrocarbures à partir d'une formation souterraine, comprenant : - l'injection d'une composition de tensioactif dans la formation souterraine, et - la collecte d'hydrocarbures déplacés par la composition de tensioactif injectée ; la composition de tensioactif comprenant au moins un composé tensioactif de formule (I) dans laquelle x est un nombre entier de 0 à 3, R1, R2, R3, R4 et chaque R représentent indépendamment un atome d'hydrogène ou un groupe alkyle, chaque A est un groupe alkylène, et le nombre total d'atomes de carbone dans le composé tensioactif de formule (I) est de 10 à 21. L'invention concerne également une composition comprenant du dioxyde de carbone liquide ou supercritique et au moins un composé tensioactif de formule (I).
