Title (EN) SOL-GEL MODIFIED PARTICULATES FOR WELLBORE FLUIDS
(FR) PARTICULES MODIFIÉES PAR UN PROCÉDÉ SOL-GEL POUR FLUIDES DE PUITS DE FORAGE
Abstract:
(EN) Methods of coating solid particulates used in a wellbore fluid are described. The methods include providing a first solution that includes at least one inorganic sol precursor and at least one solvent, adding an aqueous solution to the first solution to form an inorganic sol that develops into an inorganic sol-gel, applying the inorganic sol-gel to the solid particulates, drying the solid particulates to form an inorganic sol-gel coating on the solid particulates, and mixing the coated solid particulates with a wellbore fluid.
(FR) L'invention concerne des procédés de revêtement de particules solides utilisées dans un fluide pour puits de forage. Les procédés consistent à fournir une première solution qui comprend au moins un précurseur de sol inorganique et au moins un solvant, à ajouter une solution aqueuse à la première solution pour former un sol inorganique qui donne ensuite un sol-gel inorganique, à appliquer le sol-gel inorganique sur les particules solides, à sécher les particules solides pour former un revêtement de sol-gel inorganique sur les particules solides, et à mélanger les particules solides revêtues avec un fluide de puits de forage.
