Abstract:
Embodiments provide a method for controlled release of a cement additive for use in a wellbore. The method includes the steps of mixing an aramide capsule with a cement slurry to form an additive-containing slurry, and introducing the additive-containing slurry into the wellbore. The aramide capsule is formed by interfacial polymerization where an aramide polymer forms a semi-permeable membrane encapsulating the cement additive.

Claim (Index 1):
A method for encapsulating a cement additive for use in a wellbore, the method comprising the steps of:\n mixing a continuous solvent and a surfactant to produce a continuous phase; mixing a dispersed solvent, a dispersed monomer, and the cement additive to produce a dispersed phase, where the dispersed solvent and the continuous solvent are immiscible; mixing the continuous phase and the dispersed phase to form a mixture having an emulsion such that the dispersed phase is dispersed as droplets in the continuous phase, where an interface defines the droplets of the dispersed phase dispersed in the continuous phase; adding a crosslinker to the mixture; allowing an aramide polymer to form on the interface of the droplets, such that the aramide polymer forms a semi-permeable membrane around a core, where the core contains the dispersed phase, such that the semi-permeable membrane around the core forms an aramide capsule; allowing the aramide capsule to settle from the mixture; and separating the aramide capsule from the mixture using a separation method.
