Reversible ported sub assembly

Abstract

A reversible ported sub assembly has an upper connection assembly, a ported lower end assembly and a reversible ported jetting member. The reversible ported jetting member has a central through-bore and jet ports extending laterally from the central through-bore to the outer surface of the ported jetting member at an acute angle relative to the longitudinal axis of the central through-bore. The reversible ported jetting member can be flipped or reversed so that the jet ports can be optionally oriented generally upwardly or downwardly within a wellbore, as desired. A removable plug member can be optionally installed to prevent fluid flow through the ported lower end assembly.
