ABSTRACT:
What is disclosed is a method of forming a high-strength proppant that resists the deleterious effects of high temperature saline environments characterized by the steps of forming a plurality of particles of propping agent; and coating particles with a thin high-strength covering in a fluidized bed employing chemical vapor deposition to deposit a coating substantially uniformly over all the exposed surfaces of the particles to increase durability of the particles, as well as their strength and resistance to the deleterious effects of hot saline environment. Preferably, each particle has at least one passageway formed directly therethrough for increased permeability once deposited.
