Device and method for improving gas lift

摘要

A device and method to lower the deepest gas lift location to a deeper location within the wellbore. Providing a bottom lift tool with flexible joints to sting into a side pocket mandrel to access annular high pressure gas. Diverting that gas into the stinger through the bottom lift tool down into the wellbore below the lowest end of the production tubular and the packer and preferably to at least the bottom of the perforations in the casing.
