Composition of encapsulated chemical additives and methods for preparation of the same

A method of using an encapsulated additive in a cementing application, the method comprising the steps of:

• mixing the encapsulated additive with a cement slurry to produce an additive slurry, where the cement slurry comprises a cement and a mix water, where the encapsulated additive is formed by the steps of:
• applying a base film-forming monomer to a solid cement additive;
• forming a coating layer surrounding the solid cement additive, the coating layer comprising the base film-forming monomer;
• applying an overlay film-forming monomer to the coating layer surrounding the solid cement additive;
• and
• reacting the base film-forming monomer and the overlay film-forming monomer to produce a polymer shell,
• where the polymer shell comprises a crosslinked polymer, the crosslinked polymer comprising aramides,
• where the polymer shell surrounds the solid cement additive, and
• where the polymer shell has a permeability to water allowing controlled release of the solid cement additive;
• placing the additive slurry in a formation;
• and
• releasing the solid cement additive from the surrounding polymer shell.
