Abstract:
Capsules with a cement additive covered by a polymeric outer shell are added to wellbore cement. The additive is released from the shells by osmosis or shell ruptures. Capillary forces draw the additive into micro-annuli or cracks present in the cement, where the additive seals the micro-annuli and cracks to define a self-sealing material. The empty shells remain in the cement and act as an additive that modifies cement elasticity. The capsules are formed by combining immiscible liquids, where one of the liquids contains a signaling substance, and each of the liquids contains a reagent. When combined, the liquids segregate into a dispersed phase and a continuous phase, with the dispersed phase having the signaling agent. The reagents react at interfaces between dispersed and continuous phases and form polymer layers encapsulating the signaling agent to form the capsules. Adjusting relative concentrations of the reagents varies membrane strength and permeability.

Claim (Index 1):
A method of wellbore operations comprising:\n injecting a slurry into the wellbore, the slurry including a cement and capsules, the capsules comprising an encapsulant encased within polymeric shell; urging the slurry into an annular space between a sidewall of the wellbore and a tubular in the wellbore; and curing the slurry in the wellbore to create a set cement in the wellbore that seals against and adheres to the tubular and the sidewall to form sealing and adhering interfaces between the set cement and both of the tubular and sidewall, where the capsules are configured to increase an elasticity of the set cement, so that when one of the tubular or sidewall are displaced, the set cement correspondingly undergoes deformation to retain the sealing and adhering interfaces.
