摘要:
The present invention relates to a method for detecting and quantifying additives in a complex aqueous fluid, and in particular 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 comprising a lanthanide and a chelating agent for detecting said additives or inhibitors.
摘要:
The invention relates to 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 invention relates to nanoparticles characterized in that they each comprise (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 said nano-inhibitors and the application of same.
摘要:
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.
摘要:
The invention relates to a method for adjusting, to a pre-determined value, the level of a mineral deposition or corrosion inhibitor injected into a gas or oil well. The invention also relates to the use of the time-resolved fluorescence method for detecting and quantifying a mineral deposition or corrosion inhibitor in a fluid from an oil or gas production well.
