ABSTRACT:
A reverse up flow jet pump used in an oil and gas pumping system having a positive displacement pump on the surface supplying water flow under pressure to the jet pump down the hole. The jet pump is used in a system drawing a vacuum reducing if not eliminating the effect of head pressure within the well resulting in freer fluid flow from the formation pay zone to thereby reduce costs and increase production. Water is fed downward through an innermost pipe to a plurality of water flow diverting lines just above the jet pump body directing the water flow to and through a plurality of water flow openings extended through the jet pump body from top to bottom and at the bottom to a water flow reversing cap that reverses the water flow and directs the water flow back up a central opening narrowing for accelerated water flow into and through a venturi chamber having a venturi inlet side vent for vacuum effect drawing well fluids and/or gases from the well casing and the formation into the water flow stream for passage from the jet pump body to and up larger tubing concentric with and enclosing the innermost pipe.
