Abstract
La présente invention concerne une composition de récupération de pétrole d'une solution aqueuse d'un ou plusieurs sels et d'un polymère dilué et des procédés d'amélioration de la récupération de pétrole faisant appel à la composition de récupération de pétrole. Une composition de récupération de pétrole peut comprendre une solution aqueuse d'un ou de plusieurs sels ayant une salinité d'environ 4 000 parties par million (ppm) de matières dissoutes totales (MDT) à environ 8 000 ppm de MDT, un polymère ayant une concentration de 250 ppm à 500 ppm, des nanoparticules d'oxyde métallique à une proportion allant jusqu'à 0,1 % en poids, et du CO2 dissous. Le ou les sels peuvent comprendre du chlorure de sodium (NaCl), du chlorure de calcium (CaCl2), du chlorure de magnésium (MgCl2), du sulfate de sodium (Na2SO4) et/ou du sulfate de magnésium (MgSO4). Le polymère peut comprendre un copolymère d'acrylamide et d'acrylamido-sulfonate de butyle tertiaire (ATBS). Les compositions de récupération de pétrole selon l'invention peuvent convenir pour l'amélioration de la récupération de pétrole dans des réservoirs de carbonate présentant des viscosités in situ du pétrole inférieures à 3 centipoises (cP).
