摘要:
Methods and apparatus for subterranean well bore operations are provided. An exemplary embodiment of a method of the present invention is a method of activating a device in a subterranean well bore, the device having a baffle adapter configured to achieve sealing contact with a cementing plug, the cementing plug having an outer body and a detachable inner mandrel attached to the outer body, including the steps of: displacing the cementing plug into contact with the baffle adapter so that the outer body of the cementing plug achieves sealing contact with the baffle adapter; and applying a differential pressure across the cementing plug, thereby activating the device. An exemplary embodiment of an apparatus of the present invention is a baffle adapter, having an inner bore designed to engage and seal against the outer body of a plug.
