  • FRACTURING SLURRY COMPOSITIONS AND METHODS FOR MAKING SAME
    Publication number: 20150252254
    Abstract: The present application is directed to an aqueous slurry composition for hydraulic fracturing operations and to a method of making such a composition. In particular, the present application is directed to aqueous slurry compositions comprising a liner gel that has significantly improved capability to transport proppants in a hydraulic fracturing operation. Such aqueous slurry compositions comprise an aqueous liquid, a hydrophobically modified associative polymer, proppants and a compound that renders the proppant surface hydrophobic.
