METHODS OF PRODUCING PARTICLES HAVING TWO DIFFERENT PROPERTIES

摘要

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.

1. 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) a first type of particles, wherein the first type of particles comprise:
(a) particle cores, wherein the cores have at least a first property;(b) a coating around the outer surface of the cores or a modified surface of the cores, wherein the coating or surface has a second property, and wherein the second property is different from the first property, wherein the cores are exposed via grinding of the particles after coating or modification.
