Abstract
This invention relates to the development of nanoparticles, which can be used as tracers, in order to track the movement of fluids injected into an oil reservoir. The injected fluids diffuse through a solid geological medium which constitutes the oil reservoir, thus making it possible to study this latter by following the path of the injected fluids. The objective is in particular to monitor the flows between the injection well(s) and the production well(s) and/or to evaluate the volumes of oil in reserve and water in the reservoir and ultimately to optimize oil exploration and exploitation.
