Abstract
A downhole plug and a method of releasing a portion of the plug. The plug has a run-in configuration, a deployed configuration, and a released configuration. The plug includes a mandrel, a bull nose, and a cone and an expandable slip. The expandable slip has an external gripping surface. The plug includes an inner and outer sleeve, where the outer sleeve is concentric around the inner sleeve and the inner sleeve is concentric with the mandrel. The inner sleeve is slidable about but releasingly coupled to the mandrel. The inner sleeve is slidable about the outer sleeve but releasingly coupled to the outer sleeve in both the run-in configuration and in the deployed configuration. The inner sleeve is coupled with the mandrel in the run-in configuration and in the deployed configuration, but uncoupled and slidable about the mandrel in the released configuration.
