A method for the detection and quantification, in a complex aqueous fluid, of additives and water-soluble polymers used in the enhanced recovery of oil and shale gas.

Method for detecting and quantifying additives used in the enhanced recovery of oil and shale gas

The present invention relates to a method for determining the anionic charge density of at least one polymer present in a sample, according to the following steps:

Method for determining the anionic charge density of a polymer

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.

Method and solution for assaying inhibitors in a petroleum fluid containing water

The use, as markers of petroleum products, crude oils, biofuels or lubricants, of rare earth complexes or one of the constituents thereof chosen from rare earth ligands or salts, being capable of forming a rare earth complex after the addition of a developing solution. Preferably, the rare earth complex can be detected by time-resolved fluorescence. Also, a marking method and a method for detecting a rare earth complex as a marker of petroleum products, crude oils, biofuels or lubricants.

Use of rare earth complexes as markers of petroleum products, crude oils, biofuels or lubricants

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.
