Abstract
A method and apparatus for sealing and filling a well which may form a part of a well abandoning operation. A tube containing well filler material is connected to a bridge plug by a connector so that the bridge plug can be positioned by moving the tube and then anchored. Once the bridge plug is anchored, the tube is disconnected and the well filler can be discharged into the well above the anchored bridge plug. In this way, the bridge plug anchoring and the filling of at least a portion of the well can be performed in a single run.
