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 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.

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: 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.
