Abstract: A proppant including polyolefin-coke composite granules, a hydrocarbon well including such a proppant, and methods of forming the hydrocarbon well using such a proppant are provided herein. The hydrocarbon well includes a wellbore that extends within a subsurface region and a downhole tubular that extends within the wellbore and defines a tubular conduit. The hydrocarbon well also includes a number of perforations formed within the downhole tubular and a number of fractures formed within the subsurface region proximate to the perforations. The hydrocarbon well furthers include the proppant positioned within at least a portion of the fractures. The proppant includes a number of polyolefin-coke composite granules, where a characteristic dimension of each polyolefin-coke composite granule is at least 50 micrometers (μm) and at most 3 millimeters (mm), and where each polyolefin-coke composite granule includes a number of polyolefin polymer chains and at least one petroleum coke granule.

Abstract: A slurry including a density-tunable aqueous heavy fracturing fluid and a method for completing a hydrocarbon well using such a slurry are provided herein. The slurry includes proppant particulates and the density-tunable aqueous heavy fracturing fluid, where the density-tunable aqueous heavy fracturing fluid includes a bromide-based compound. The density of the density-tunable aqueous heavy fracturing fluid is between 1 gram/cubic centimeter (g/cc) and 3.6 g/cc.
