ABSTRACT:
A downhole or subterranean tool for use with a subsurface strata producing both hydrocarbon gas and water in which the gas and water are separated downhole by gravity and the gas is produced to the surface through one channel, and the water is disposed into a lower subterranean disposal zone. A production tubing is suspended within a casing which lines a well bore drilled through the two zones. A sucker rod actuated reciprocating pump is located in the production tubing. A seating nipple bypass tool with longitudinal holes and side ports in the wall thereof surrounds the pump. This bypass tool is positioned between the producing zone and a lower zone which is to be used as a disposal zone for the salt water. Gas is produced upwardly through the annulus between the tubing and the casing, and the salt water is flowed down through the longitudinal tubes in the sleeve to be disposed in the lower zone.
