A rod pump having a plunger connected to a hollow rod string can positively pump the liquids collecting at the bottom of the well while the natural gas is produced up the annulus between the production tubing and the hollow rod string. In this invention, the tail pipe is perforated above the rod pump and below the packer to all the natural gas into the production tubing.
