FIELD: technological processes.
SUBSTANCE: invention relates to a method for inhibition of scale, for instance, barium-containing deposits, in a water system. The method includes pumping an aqueous solution of a scale inhibitor into wells of oceanic field, and the scale inhibitor is an amino acid modified with alkyl phosphonic acid in concentration from 0.1 to 100000 parts per million. A fragment of an amino acid may represent α-amino-acid or amino-acid that contains two or more atoms of carbon between a carboxyl group and an amino group.
EFFECT: method makes it possible to perform continuous oil production with efficient monitoring of scale formation using lower concentrations of an inhibitor.
