Abstract
A proppant composition includes: a volume of water; a self-suspending proppant, including a plurality of proppant granules each with a hydrophilic polymer coating, the hydrophilic polymer coatings of the self-suspending proppant together defining a total polymer volume; and an untreated proppant, where a concentration of the self-suspending proppant in the water is sufficient (i) to reduce the water to an unabsorbed volume of less than 25% of the volume of water and (ii) to hydrate at least 75% of the total polymer volume.
