Abstract
The fluid tracers according to the invention have the advantage of producing a memory effect fluorescent signal, that is to say a signal modified as a function of the physico-chemical conditions encountered in the medium through which the nanoparticles pass after injection into the geological underground area. The analysis of fluorescent signals in the fluids collected after diffusion makes it possible to deduce therefrom information on the characteristics of the oil reservoir.
