Abstract:
A system for applying low pressure gas lift artificial lift enables improved efficiency in gas and oil well production. The system comprises: a central tubing in a well hole of the well, the tubing having a well head end and a well sump end; an annulus that extends around the central tubing between from the well head end to the sump end; a compressed gas source; a gas lift gas line connecting the compressed gas source to the well hole; a gas compressor having an input and an output, wherein the output is connected to the annulus; a flowline connected to the well head end of the central tubing; and an automatically controlled flowline choke in the flowline.
