Abstract: A seal cartridge and barrel manifold seal are provided for use in a subterranean well and in a method to inject fluid, that is initially produced into the well from a subterranean formation or zone, into another subterranean formation or zone. The seal cartridge has two distinct annular seals positioned within opposite sides of a unitary housing to inhibit fluid flow through the housing in both axial directions along a rod that is positioned through the housing. A barrel seal manifold is provided that is unitary in design and has tapered flow surfaces thereby provided increased strength, flow dynamics and life.

Abstract: A full flow tubing stationary valve pump apparatus includes an cuter annulus barrel, an inner working barrel positioned in radially inwardly spaced relation from the outer annular barrel to define a vertical flow annulus therebetween, an elongated inner plunger disposed within and vertically movable by upstrokes and downstrokes relative to the inner working barrel, a lower intake valve assembly disposed within and supported by the outer annulus barrel below the inner plunger, and an upper discharge valve assembly disposed within and supported by the outer annular barrel below the inner plunger and above the lower intake valve assembly.

Abstract: A dual annulus production tool includes an upper annular seal provided in a sealing relationship with well casing bore below ground surface and above an opening in the casing, an elongated outer tubing in the casing bore extending from ground surface downward through and in a sealing relationship with the upper annular seal to an lower end of the outer tubing located below the upper annular seal, the outer tubing and casing defining an outer annulus therebetween extending from above the upper annular seal to the ground surface, an elongated inner tubing in the casing bore within the outer tubing extending from ground surface downward to a lower end of the inner tubing located below the upper annular seal, the outer and inner tubings defining an inner annulus therebetween for routing flow of fluid from below the upward annular seal upward through the inner annulus to ground surface without entering the outer annulus, and an annular housing in the casing bore below the upper annular seal and adjacent to a well

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.
