Abstract

The present disclosure is directed to a system and method for sonically activating cement slurries. In some implementations, a method of treating a subterranean formation includes positioning a settable composition including a capsule in a wellbore. The capsule is used to increase a setting rate in response to at least sonic signals. A sonic signal is transmitted to at least a portion of the settable composition to release an activator from the capsule.
