ABSTRACT:
A superior proppant having very high permeability at formation pressures up to 20,000 psi, very high compressive strength, low specific gravity, and good acid resistance, is produced by a process comprising: (a) separating a fine fraction from a naturally occurring bauxite containing same; (b) pelletizing the separated fine fraction in the presence of water; (c) treating the pellets produced in step (b) to remove water therefrom; and (d) sintering the product of step (c) to produce a low density material suitable for use as a proppant.
