ABSTRACT:
An integrated side-entry sub with grease injection flow tubes is adapted for making up in a drill string and includes a port to receive a cable, such as a wire line. A first pedestal, mounted within a cutout of the side entry sub, provides entry for the cable into the entry port. The first pedestal receives a first flow tube, which couples to a lower connector manifold. The lower connector manifold further provides a grease injection port. A second flow tube, coupled to the lower connector manifold, runs to an upper connector manifold. The upper connector manifold further provides an grease return port, as well an the entry point for cable into the sub.
