ABSTRACT:
A novel method of injecting or squeezing a cross-linked scale inhibitor down a well into a subterranean formation which significantly lengthens its effective life is accomplished by cross-linking a carboxylic acid-containing polymeric or organophosphorus-containing inhibitor with a polyalcohol. The significant extension of life afforded by cross-linking with a polyalcohol improves the overall economics of oil production in fields prone to mineral scale.
