Abstract: A through tubing bridge plug is disclosed. In the preferred and illustrated embodiment, a central hollow tube having a passage therein supports the external parts. The central passage terminates top and bottom with openings or passages. At the top end, a sleeve valve mechanism originally pinned in an open position is installed. When the installation is completed, the sleeve valve is closed by a sequence of operations to permanently close the flow path. The device is set and anchored by applying a relative downward force to an external sleeve thereby deploying slips to lock the device in location, additionally deploying an upwardly facing petal basket to receive a charge of sand and cement to form a plug, and also deploying a centralizer.
