Title
(EN) METHODS OF PRODUCING PARTICLES HAVING TWO DIFFERENT PROPERTIES
(FR) PROCÉDÉS DE PRODUCTION DE PARTICULES AYANT DEUX PROPRIÉTÉS DIFFÉRENTES
Abstract
(EN) A method of producing particles comprising: (A) providing a plurality of particle cores, wherein the cores have at least a first property; (B) partially or fully coating the outer surface of the cores with a substance, wherein the substance has a second property, and wherein the second property is different from the first property; and (C) reducing the particle size of the coated particles, wherein the core is exposed after the step of reducing. A method of using particles comprising: introducing a treatment fluid into an area to be treated, wherein the treatment fluid comprises: (i) a base fluid; and (ii) the particles.
(FR) Cette invention concerne un procédé de production de particules comprenant : (A) la préparation d'une pluralité de cœurs de particules, lesdits cœurs ayant au moins une première propriété; (B) le revêtement partiel ou complet de la surface extérieure des cœurs avec une substance, ladite substance ayant une seconde propriété, et la seconde propriété étant différente de la première; et (C) la réduction de la taille de particule des particules revêtues, le cœur étant exposé après l'étape de réduction. Un procédé d'utilisation des particules comprenant : l'introduction d'un fluide de traitement dans une zone à traiter, le fluide de traitement comprenant : (i) un fluide de base; et (ii) les particules selon l'invention est en outre décrit.
