ABSTRACT:
An inexpensive oil well pumping mechanism is largely made of commercially available plastic components. An air line leads from an air compressor at the surface into the well. One or more pumps are connected to the air line and include a pneumatic displacement chamber which is arranged to fill up with formation liquids. A float inside the chamber rises when the chamber fills and trips a valve to allow compressed air entry into the chamber. The chamber accordingly empties into a conduit leading toward the surface.
