    摘要: 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.

    摘要: Methods and apparatus for preventing or limiting the rotation of downhole tools, such as cementing plugs, in a casing string during drillout. The apparatus includes an outer case and a radially expandable sleeve disposed therein. The sleeves will engage cementing plugs received therein. The sleeves radially expand when cementing plugs are received therein to grippingly engage the outer case and prevent or limit rotation thereof during drillout.
