Abstract

See full text

Apparatus and methods for reducing pressure exchanger manifold resonance. Example apparatus include a first manifold and pumps fluidly connected with the first manifold. Each pump is operable to inject a pressurized clean fluid into the first manifold. The apparatus may further include a second manifold and pressure exchangers each fluidly connected with the first and second manifolds. Each pressure exchanger is operable to receive the pressurized clean fluid from the first manifold and discharge the pressurized dirty fluid into the second manifold. The apparatus may also include a first flow restricting orifice fluidly connected along the first manifold, a second flow restricting orifice fluidly connected along the second manifold, and a discharge conduit fluidly connected with the wellbore to permit the pressurized dirty fluid to be injected into the wellbore during a well treatment operation.
