International Classification:

F16L 41/03
E21B 43/26

Abstract:

A fluid manifold segment operable for detachably coupling with another instance of the fluid manifold segment to form a fluid manifold assembly. The fluid manifold segment may include a plurality of pressure exchangers each having a clean fluid inlet a clean fluid outlet, a dirty fluid inlet, and a dirty fluid outlet. The fluid manifold segment may further include a first fluid conduit having opposing end ports and intermediate ports, a second fluid conduit having opposing end ports and intermediate ports each fluidly connected with the clean fluid outlet of a corresponding pressure exchanger, a third fluid conduit having opposing end ports and intermediate ports each fluidly connected with the dirty fluid inlet of a corresponding pressure exchanger, and a fourth fluid conduit having opposing end ports and intermediate ports each fluidly connected with the dirty fluid outlet of a corresponding pressure exchanger.

Abstract:

A choke for fluid connection between a manifold and a pump. The choke includes a fluid passage having an inlet, a contraction portion, a throat, an expansion portion, and an outlet. The inlet has a first diameter and the outlet has a second diameter. The throat is substantially cylindrical, having a third diameter that is substantially less than the first and second diameters. The contraction portion connects the inlet and the throat and gradually decreases from the first diameter to the third diameter along a longitudinal axis of the fluid passage. The expansion portion connects the throat and the outlet and includes a substantially cylindrical chamber having the second diameter.
