ABSTRACT:
A wireline-set retrievable packer with the flow plug on top is disclosed which uses a conventional setting tool. After setting the packer, picking up on the wireline allows the adapter assembly to disengage from the on/off seal nipple/packer so that the setting tool and adapter assembly can be removed.
