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. |
