Abstract: Lost circulation particles are commonly used in drilling and/or cementing operations to prevent fluid loss to a subterranean formation. Drilling fluids and methods of drilling and/or cementing operations may also use petroleum coke lost circulation particles composed of fluid coke and/or flexicoke material. Such petroleum coke lost circulation particles may have improved transport into wellbores because of their lower density compared to traditional lost circulation material and may produce fewer fines that can interfere with lost circulation efficacy.

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: 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 agitated petroleum coke particles (referred to as agitated petroleum coke proppant particulates). In some instances, the agitated petroleum coke proppant particulates are characterized by a particle density of equal to or less than about 1.6 grams per cubic centimeter. The agitation processing of the present disclosure can remove petroleum coke particles having initiated cracking or scissions that are prone to fines production.

Abstract: A fracturing fluid including proppant particulates formed from delayed coke, as well as a method for utilizing such fracturing fluid, are provided herein. The fracturing fluid includes a carrier fluid, as well as proppant particulates composed of delayed coke material. The method includes introducing the fracturing fluid into a subterranean formation and (optionally) depositing at least a portion of the proppant particulates within one or more fractures in the subterranean formation.

Abstract: Highly crosslinked polymer particulate and methods of manufacturing highly crosslinked polymer particulate. The highly crosslinked polymer particulate includes a plurality of crosslinked polymer granules. Each crosslinked polymer granule includes a highly crosslinked polymeric material and a property-modifying filler. The highly crosslinked polymeric material includes a plurality of polyethylene polymer chains and a plurality of chemical crosslinks. The the plurality of chemical crosslinks includes chemical crosslinks that covalently bond a given polyethylene polymer chain of the plurality of polyethylene polymer chains to another polyethylene polymer chain of the plurality of polyethylene polymer chains. The property-modifying filler is configured to modify at least one property of the plurality of crosslinked polymer granules. A characteristic dimension of each crosslinked polymer granule of the plurality of crosslinked polymer granules is at least 10 micrometers and at most 5 millimeters.

Abstract: Methods for utilizing an acid blend to prevent and/or remove blockages encountered during the hydraulic fracturing of a near-wellbore region of a subterranean formation are provided herein. The methods include using an acid blend to dissolve formation mineralogies within close proximity to perforations and corresponding fractures that have experienced or are likely to experience blockages, such as blockages caused by the embedment of proppant into the perforation tunnels and/or the fractures. The acid blend used according to the methods described herein includes an acid mixture including hydrochloric acid and hydrofluoric acid. In addition, the acid blend may also include a chelating agent.
