Abstract
The present invention involves a remote sub sea lubricator assembly for inserting a wireline tool into a sub sea well comprising an elongated tube having an axial passage formed therethrough for receiving the wireline tool. The remote sub sea lubricator is lowered beneath the surface of the sea for connection to a sub sea well. Contained within the lubricator is the wireline tool. Once connected to the sub sea well, the wireline tool is released from the lubricator into the well. The lubricator enables the wireline tool to enter and exit the well without sea water entering the well.
