Title (EN) METHOD FOR PRODUCING WATER FOR ENHANCED OIL RECOVERY
(FR) PROCÉDÉ DE PRODUCTION D'EAU POUR UNE RÉCUPÉRATION ASSISTÉE DU PÉTROLE
Abstract: front page image
(EN)A combination of membrane processes is disclosed which can produce designer salt brine for enhanced oil recovery using seawater as the only feed source. The membrane processes used are reverse osmosis, nanofiltration and electrodialysis. The chemistry of the brine can be tightly controlled in terms of TDS, low sulfate levels and ratio of monovalent cations to divalent cations.
(FR)L'invention concerne une combinaison de traitements par membranes permettant de produire une saumure pour une récupération assistée du pétrole au moyen de l'eau de mer comme source d'alimentation unique. Les traitements par membranes utilisés sont l'osmose inverse, la nanofiltration et l'électrodialyse. La composition chimique de la saumure peut être strictement contrôlée en termes de TDS, de faibles taux de sulfates et de rapport de cations monovalents à cations divalents.
