Abstract: Method for increasing lubricity of a wellbore fluid comprising the following steps: i) preparing a water in oil microemulsion that contains insoluble particles of metal hydroxides and/or metal oxides in the inner aqueous phase, the insoluble particles being synthesized from their salt precursors in the water droplets of the microemulsion; ii) adding to the wellbore fluid the water in oil microemulsion; iii) injecting the wellbore fluid into a subterranean formation and iv) performing the drilling, completion or coiled tubing operations in the subterranean formation.
