Abstract
A stinger for insertion into a polished bore receptacle is operable between at least two operational states. The at least two operational states include a closed state in which fluid flow through the through bore of the plug section is prevented and an open state in which fluid flow through the through bore of the plug section is allowed. An actuating system is operating the stinger from the closed state to the open state. The stinger is brought to the open state from the closed state as the stinger is pushed down into polished bore receptacle.
