摘要： A copolymer containing a unit including an optionally neutralized styrene sulphonic acid unit and a unit containing at least one optionally neutralized (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, including the injection of a fluid containing the abovementioned copolymer into a wellbore, a subterranean formation or a gas or oil well.

摘要： Novel hybrid nanoparticles, useful for inhibiting or slowing down the formation of sulfur deposits or minerals in a well during the extraction of gas or oil. Specifically, the nanoparticles each include (i) a polyorganosiloxane (POS) matrix; and, optionally as a coating over a lanthanide oxide core, (iii) at least one polymeric scale inhibitor during the extraction of gas or oil. The invention also relates to the method for obtaining the nano-inhibitors and the application of same.

摘要： A method for detecting and quantifying additives in a complex aqueous fluid, and a method for detecting an inhibitor of mineral deposition or corrosion, injected in a gas or oil well. The invention also relates to a developer solution including a lanthanide and a chelating agent for detecting said additives or inhibitors.
