  • Patent number: 12516598
    Abstract: A method of performing a wellbore servicing operation may include: obtaining a measurement of steady state creep rate () within a cement sheath associated with a wellbore while performing the wellbore servicing operation in the wellbore; determining a number of cycles to failure (Nf) of the cement sheath using a cement material fatigue model wherein the cement material fatigue model has an input of steady state creep rate (); adjusting at least one operational parameter of the wellbore servicing operation in response to the determined number of cycles to failure (Nf) to form adjusted operational parameters; and performing the wellbore B servicing operation at the adjusted operational parameters.

  • Patent number: 12435260
    Abstract: A hardened cement produced by setting a cement slurry including an asphaltite (e.g., GILSONITEā„¢ 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.

  • Publication number: 20250179345
    Abstract: A hardened cement produced by setting a cement slurry including graphene comprising bioderived renewable graphene (BRG), a cement, and water. The graphene of the cement slurry comprises, consists essentially of, or consists of BRG, and the cement slurry comprises at least 0.2 (e.g., from about 0.2 to about 20) percent graphene comprising BRG by weight of cement (% graphene bwoc). The hardened cement produced by allowing the cement slurry to set has one or more enhanced mechanical properties (e.g., increased Young's modulus (YM), 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 comprising a same total amount of graphene, with synthetic graphene (SG) in place of at least a portion of the BRG. Methods of cementing with the cement slurry are also provided.

  • Publication number: 20240141135
    Abstract: Methods and compositions for performing a wellbore operation in a subterranean formation. An example method introduces a resin-based material into a wellbore. The resin-based material is a resin and a boron nitride nanotube structure comprising a boron nitride nanotube having a hexagonal boron nitride structure epitaxial to the boron nitride nanotube. The example method performs the wellbore operation in the wellbore with the resin-based material.
