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 1):
A method of wellbore operations comprising:\n providing a first fluid having a signaling agent and a first reagent; providing a second fluid that is immiscible with the first fluid and that contains a second reagent that is combinable with the first reagent to form a polymer; combining the first and second fluids so that the first fluid is dispersed in the second fluid to form vesicles of the first fluid in the second fluid, and so that the first and second reagents react at interfaces between the first and second fluids to form polymer layers that encapsulate the vesicles, and which form capsules containing the signaling agent; controlling a characteristic of the polymer layers by adjusting a concentration of a one of the first and second reagents; disposing the capsules in a wellbore; and monitoring for the presence of signaling agents that escape from the capsules.
