Abstract (en)
[origin: WO2017121669A1] The invention relates to a method for the tertiary recovery of petroleum from underground deposits having a deposit temperature of ≤ 70°C, wherein a copolymer comprising (meth)acrylamide or derivatives thereof, monoethylenically unsaturated carboxylic acids, in particular acrylic acid, and an associative monomer is used, wherein the amount of the associative monomer is 0.1 to 0.9 wt%. A water-soluble copolymer comprising (meth)acrylamide or derivatives thereof, monoethylenically unsaturated carboxylic acids, in particular acrylic acid, and 0.1 to 0.9 wt% of an associative monomer.
