Summary: | The present invention relates to the use of a copolymer containing a unit comprising an optionally neutralised styrene sulphonic acid unit and a unit containing at least one optionally neutralised (poly)carboxylic acid unit or a (poly)amido-amine unit, to inhibit or slow the formation of sulphide deposits during the extraction of gas or oil. It also relates to a method to inhibit or slow the formation of sulphide deposits during the extraction of gas or oil, comprising the injection of a fluid containing the abovementioned copolymer into a wellbore, a subterranean formation or a gas or oil well. |
