What is a bottom hole packer?
A bottom hole packer is a type of work over tool. One possible application is to bridge and isolate a section of damaged casing. It is only about 2 feet long and has a seal on the side and end. It screws onto the end of a short liner and is designed to land on top of an existing liner hanger. An adapter is usually attached to the other end of the liner. The assembly is run into the well where the bottom hole packer lands on top of the liner hanger. The seals are set via weight from the rig. The adapter may also have a seal which is set at the same time, thus isolating the bad section of casing.
