Method for enhanced oil recovery by injecting an aqueous polymeric composition containing microgels |
| abstract |
The present invention relates to a method for enhanced oil recovery by flushing an underground formation, comprising the injection into the underground formation of an aqueous composition comprising microgels having at least one crosslinked polymer, characterized in that the polymer is crosslinked with at least one crosslinking agent capable of being degraded under the temperature conditions of the underground formation, and a content of crosslinking agent between 1 and 90 ppm per mole with respect to the total number of moles of monomer constituting the polymer. |
