Abstract
A downhole manifold assembly includes a manifold body defining a longitudinal axis and having a first end face, a second end face, and an outer surface extending therebetween. A fluid circuit is defined in the manifold body and includes a plurality of axially extending fluid passages and a plurality of radially extending fluid passages. The radially extending fluid passages extend to the outer surface of the manifold body. Each radially extending fluid passage defines a respective aperture in the outer surface. The manifold assembly also includes a control valve coupled to the manifold body. The control valve is positionable between a first position in which a flow of pressurized fluid is channeled through the fluid circuit in a first direction, and a second position in which the flow is reversed and the pressurized fluid is channeled through the fluid circuit in a second direction.
