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 petroleum coke material. Such proppant particulates may have improved transport into fractures because of lower density than traditional proppants like sand and may produce fewer fines that reduce fluid flow through proppant packs. The proppant particulates of the present disclosure are composed of thermally post-treated delayed coke and exhibit mechanical properties comparable to fluid coke and flexicoke petroleum coke materials for use as proppant particulates.
