| titleOfInvention | Process for treating aqueous fluid containing polymers with zirconium salts and alkali metal carboxylates |
| abstract | The invention relates to a process for treating an aqueous fluid comprising at least one water-soluble polymer bearing carboxylate or sulfonate functions in aqueous phase, said process comprising a step of contacting said aqueous fluid with at least one tetravalent zirconium salt and at least one alkali metal carboxylate selected from alkali metal citrates or alkali metal propionates, enabling a reduction in the viscosity of said aqueous fluid, so as to produce an aqueous fluid having a lowered viscosity preferably close to that of water. The invention likewise relates to a process for enhanced recovery of crude oil present in a geological reservoir, in which the production water obtained is treated with said process for treating an aqueous fluid. |
