Abstract (en)
[origin: EP2457973A1] Use of a water soluble and hydrophobically associating copolymer comprising (a) at least one monoethylenically unsaturated water soluble and surface-active monomer, and (b) at least one monoethylenically unsaturated hydrophilic monomer that is different from monomer (a), as an additive in the development, exploitation and completion of underground crude oil and natural gas deposits, is claimed. A further component comprising (c) at least one non-polymerizable and surface active compound is added during the synthesis of the copolymer before initiating the polymerization reaction.
