Abstract
An aqueous slurry composition for use in industries such as petroleum and pipeline industries, such as for use as a fracturing fluid. The aqueous slurry composition includes a particulate, an aqueous liquid and a chemical compound that renders the particulate surface hydrophobic. The slurry is produced by rendering the surface of the particulate hydrophobic during or prior to making the slurry.

26-31. (canceled)
34-48. (canceled)
A method of preparing an aqueous fracturing slurry composition comprising the following steps:
- (a) treating particulates by contacting the particulates with a liquid medium comprising an amine functionalized hydrophobic polymer to render the surfaces of the particulates hydrophobic;
- (b) separating the treated particulates from the liquid medium;
- (c) mixing the treated particulates with an aqueous liquid to form an aqueous slurry composition.
