Synergistic Effects of Asphaltite and Graphene on Cement Resilience

Abstract: a hardened cement produced by setting a cement slurry including an asphaltite (e.g., gilsonite™ uintaite), graphene (e.g., bioderived renewable graphene (brg), non-brg graphene, a synthetic graphene, or a combination thereof), a cement, and water. the cement slurry can comprise from about 0.2 to about 20 weight percent of the asphaltite and from about 0.2 to about 20 weight percent of the graphene by weight of cement (% graphene bwoc). the hardened cement has one or more enhanced mechanical properties (e.g., increased compressive strength (cs), or increased resiliency as indicated by an increased reduction in a ratio of ym/cs) relative to a same hardened cement produced by allowing to set a same cement slurry absent the asphaltite and/or the graphene. methods of cementing with the cement slurry are also provided.
