Abstract: An above production disposal tool for use in a production well having a lower production formation and an upper disposal formation includes an outer tube body, upper and lower annular seals, an upper tube member, an upper collar having a plurality of outlet port holes, a lower tube member, a lower collar having a plurality of inlet port holes, an upper inner by-pass tube, a lower inner by-pass tube, a middle collar disposed between upper and lower tube portions of the outer tube body and having a plurality of axial passageways and a plurality of transverse ports, and a tubing pump having an intake port located below the production formation. The outer tube body, upper and lower tube members and tubing pump are incorporated in a tubing string disposed in the production well with the outer tube body extending along the disposal formation which is sealed above and below by the annular seals.

Abstract: A formation injection tool disposable in a casing of a production well includes an intake flow control assembly, a seal mechanism located below the intake flow control assembly, and a discharge flow control device located below the seal mechanism. The intake flow control assembly is attached to a lower end of a pump extending downward within the well casing past and below an upper productive formation. In response to an upstroke of the pump, the intake flow control assembly permits one-way flow of undesired heavier fluid, such as water, from the upper productive formation downwardly and into the intake flow control assembly concurrently as desired lighter fluid, such as oil and/or gas, flows from the upper productive formation upwardly within the well casing to the ground surface. The seal mechanism establishs a closure seal within the well casing between the upper productive formation and lower disposal formation.
