Lewis, S. J., Davis, J., Roberson, M., Badalamenti, A., Reyes, P., & Roddy, C. W. (2012). IPC No. U.S.Methods of Activating Compositions in Subterranean Zones (Patent No. 8162055.)

The present disclosure is directed to a system and method for managing cement in a subterranean zone. In some implementations, a method of cementing in a subterranean formation includes positioning a cement slurry including a plurality of activation devices in a wellbore. The activation devices configured to release an activator that increases a setting rate of the cement slurry. A signal is transmitted to at least a portion of the cement slurry to activate the activation devices. The activation device releases the activator in response to at least the signal.
