  • Use of rare earth complexes as markers of petroleum products, crude oils, biofuels or lubricants
    Patent number: 10975318
    Abstract: 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 a copolymer made from styrene sulphonic acid to inhibit or slow the formation of sulphide deposits
    Patent number: 10106722
    Abstract: 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.
