  • Method of drilling a wellbore
    Patent number: 11339317
    Abstract: A method of minimizing the weight loss of mass of the drilling pipe and wellbore casing while drilling a subterranean well with an oil-based drilling fluid comprising adding to the oil-based drilling fluid an anti-wear additive based on sulfated, sulfonated or sulfited natural oils or fats of vegetable or animal origin.

  • Method of increasing lubricity of wellbore fluids
    Patent number: 10611948
    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.
