Abstract (en)
[origin: WO2019120771A1] The present invention concerns a method for exploiting an underground formation, in which at least one fluid is injected. According to the invention, the fluid comprises at least one additive, the additive being constituted by at least one adjuvant linked to at least one magnetic nanoparticle. In this way, by applying a magnetic field, the additive can be separated from the effluent produced.
