Abstract
A system including a plug with a first end connected to a lower drill string and a second end connected to an upper drill string. The plug further includes a sealing element configured to seal against a reservoir pressure that is downhole from the plug, and an anchoring element configured to releasably couple the plug to a wellbore to disallow an axial movement of the plug in the wellbore. The plug is configured to couple to a retrieving tool. The retrieving tool includes a first engagement element configured to release the anchoring element, thereby allowing axial movement of the plug and retrieval of the upper drill string in order to shut in the wellbore.
