Emulsion shear bond enhanced cement

A method of forming a precursor cement slurry, comprising:

• introducing into a cement powder a dry additive that is not a cement bond enhancer such that a dry mixture forms;
• introducing a water-soluble fluid additive and the cement bond enhancer into a water such that a wet suspension forms, where the cement bond enhancer is comprised of the reaction product of graphene oxide with an anchoring functionality;
• introducing a non-aqueous fluid additive into the wet suspension such that a Pickering emulsion forms, where the non-aqueous fluid additive is an internal phase and the cement bond enhancer stabilizes the non-aqueous fluid additive and;
• and
• introducing the dry mixture into the Pickering emulsion such that the precursor cement slurry forms.

A method for cementing an annular space within a wellbore:

• comprising:
• introducing a precursor cement slurry into the wellbore such that it is positioned in the annular space in the wellbore;
• and
• maintaining the wellbore such that the precursor cement slurry cures into a product cement in the annular space,
• where the precursor cement slurry comprises:
• a cement powder;
• water;
• and
• an additive, where the additive includes a cement bond enhancer and a hydrocarbon solvent;
• where the hydrocarbon solvent is an internal phase and the cement bond enhancer stabilizes the hydrocarbon solvent in the form of a Pickering emulsion within the precursor cement slurry and where the cement bond enhancer is comprised of the reaction product of graphene oxide with an anchoring functionality.
