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. Desired light fluid enters an inner annular passage defined between the inner by-pass tubes and the outer tube body through the inlet port holes below the lower seal and exits above the upper seal through the outlet port holes, by-passing the disposal formation. Undesired heavier fluid is pumped through the intake port into an interior passage defined by the upper and lower tube members and the upper and lower by-pass tubes and out the transverse ports of the middle collar into the disposal formation.
