The present invention concerns a process for developing a subterranean formation, in which at least one fluid is injected. In accordance with the invention, the fluid comprises at least one additive, the additive being labelled with at least one luminescent semiconductor nanocrystal (fluorescent or phosphorescent). In this manner, and by optical analysis of the presence of luminescent semiconductor nanocrystal in the fluid recovered from the subterranean formation, the presence and/or quantity of additive in the recovered fluid can be determined. Given that the semiconductor nanocrystal is either phosphorescent or fluorescent, the additive is rendered readily detectable and quantitatively determinable in the fluids recovered from the subterranean formation.
