Abstract:
A method of monitoring conditions in a wellbore by disposing capsules with a signaling agent downhole, and monitoring the presence of the signaling agent released from the capsules that escape the wellbore. The capsules are formed by combining immiscible liquids, where one of the liquids contains the 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 the interfaces between dispersed and continuous phases and form polymer layers encapsulating the signaling agent to form the capsules. When disposed downhole, such as in casing cement, the capsule membranes can burst under pressure or temperature to release the signaling agent. Adjusting relative concentrations of the reagents varies membrane strength and permeability.

Claim (Index 12):
A method of wellbore operations comprising:\n combining first and second solutions that each comprise a reactive monomer and a fluid that is immiscible with a fluid in the other solution, and at least one of the first or second solutions having a signaling agent; forming an emulsion with the first and second solutions that comprises a continuous phase, and amounts of a dispersed phase containing the signaling agent and distributed within the continuous phase; forming polymeric layers around the amounts of the dispersed phase by reacting the monomers that define capsules containing the signaling agent; adjusting a concentration of a one of the reactive monomers to adjust a characteristic of polymer layers; disposing the capsules in cement that lines a wellbore; and evaluating a condition of the cement by sensing signaling agent that has escaped from the capsules in the cement.
