Title (EN) USE OF NANOPARTICLES AS A LUBRICITY ADDITIVE IN WELL FLUIDS
(FR) UTILISATION DE NANOPARTICULES EN TANT QU'ADDITIF PRÉSENTANT UN POUVOIR LUBRIFIANT DANS DES FLUIDES DE FORAGE
Abstract:
(EN) A use of nanoparticles in a well fluid for improved lubricity is disclosed herein. The nanoparticles are present in the well fluid in low amounts below 5 wt%. The nanoparticles may be formed ex situ and added to the fluid or in situ in the fluid. In one aspect, the well fluid is a drilling fluid. In a further aspect, the well fluid is an invert emulsion based fluid or an aqueous based fluid.
(FR) L'invention concerne une utilisation de nanoparticules dans un fluide de puits pour un pouvoir lubrifiant amélioré. Les nanoparticules sont présentes dans le fluide de puits en de faibles quantités inférieures à 5% en poids. Les nanoparticules peuvent être formées ex situ et ajoutées au fluide ou in situ dans le fluide. Dans un aspect de l'invention, le fluide de puits est un fluide de forage. Dans un autre aspect de l'invention, le fluide de puits est une émulsion inverse à base de fluide ou un fluide à base aqueuse.
