ABSTRACT:
A process for fixing of a scale inhibitor in a subterranean formation, which comprises:
a) injecting into the formation a solution comprising a polymeric scale inhibitor, a metal cation, a precursor and a weak organic acid, wherein the polymeric scale inhibitor and metal cation are slightly soluble in water in the formation and wherein the precursor reacts in the formation to produce an alkaline compound which causes the polymeric scale inhibitor to precipitate in the formation; and
b) allowing the polymeric scale inhibitor to precipitate in the formation in an amount which is effective in inhibiting scale formation for a given period of time.
