Abstract
Proppant particulates like sand are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. Fracturing fluids and methods of hydraulic fracturing may also use proppant particulates composed of fluid coke material (also referred to as fluid coke proppant particulates). In some instances, the fluid coke proppant particulates are characterized by a bulk density of less than about 0.9 grams per cubic centimeter.
