A new class of multifunctional tracers has been synthesised for use in the oil industry, specifically during waterflooding operations. They are used either in a traditional way (i.e. mapping the connections of oilfield selections) or to provide information on important physical- chemical parameters (such as oil content, temperature and rock permeability) useful for optimizing the oilfield management and subsequent improvement/increase in oil extraction. Une nouvelle classe de traceurs multifonctionnels a été synthétisée pour être utilisée dans l'industrie pétrolière, en particulier pendant des opérations d'injection d'eau. Ils sont utilisés soit de manière classique (c'est-à-dire, cartographier des liaisons de sélections de champs pétrolifères) ou pour fournir des informations sur des paramètres physico-chimiques importants (tels que la teneur en huile, la température et la perméabilité à la roche) utiles pour l'optimisation de la gestion de champs pétrolifère et l'amélioration/l'augmentation ultérieure de l'extraction d'huile.
