Abstract
A sand slurry composition and a method for making sand slurries are disclosed. The sand slurry composition is comprised of sand, an aqueous liquid and a chemical compound that renders the surface sand of hydrophobic. The method is comprised of rendering sand surface hydrophobic during or before making the slurry. This method and composition can find many applications in different industries, especially in various oil field applications.
Claims25
A method of preparing a fluid composition for a fracturing operation comprising mixing together:
- a. proppants,
- b. water, and
- c. a collector which renders the surface of the proppants hydrophobic.
- wherein the collector is selected from a group consisting of a primary amine, a secondary amine, a tertiary amine, a primary ether amine, an ether diamines, a tallow amine, and a tallow oil fatty acid/amine condensate.

A method of making an aqueous slurry composition for hydraulic fracturing operation comprising:
- a) contacting proppant with a medium containing a collector to render the proppant hydrophobic;
- b) separating the proppant from the medium, and
- c) mixing the treated proppants with water under shear in the presence of a gas;
- wherein the collector is selected from a group consisting of a primary amine, a secondary amine, a tertiary amine, a primary ether amine, an ether diamines, a tallow amine, and a tallow oil fatty acid/amine condensate.
