摘要： 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. Using 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.

摘要： 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.
