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 22):
An aramide capsule for use in a cement environment, the aramide capsule comprising:\n a semi-permeable membrane comprising an aramide polymer, the semi-permeable membrane forming a shell with a core, such that the core contains a cement additive, the semi-permeable membrane operable to allow the cement additive to permeate from the core through the semi-permeable membrane to the cement environment; and the cement additive, the cement additive operable to impart a beneficial interaction on the cement environment, where the aramide polymer comprises subunits derived from a monomer including a di-functional amino group and subunits derived from a crosslinker including an acyl chloride.
