    Abstract: A method and apparatus for sealing and filling at least a portion of a well is disclosed. This may form a part of a well abandoning operation. In particular, according to the present disclosure, a tube containing well filler material is connected to a bridge plug by a tube-plug connector wherein 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 may 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.

    Abstract: A downhole tool having a diverter component for directing fluids in different directions within a wellbore. The diverter component has an outer pipe which forms part of the downhole string. The pipe has a through channel and holes through the wall of the pipe. Within the pipe is a sleeve which can be moved. In one position, the sleeve blocks the wall holes and allows fluid to pass through the channel of the pipe. The diverter component may be used in conjunction with packers to seal off sections of the wellbore. The diverter and packer assembly could be used to introduce acid into particular portions of the wellbore.
