<p>Diverter tool (10) for diverting a pump-down tool (PDT, 22) along various branches of a pipeline (14). The diverter includes a flapper (20) to redirect the PDT along an alternate conduit (15) of a wye-section (16) of the pipeline. The flapper is hydraulically operated by an actuation chamber (19) at the lower end of the diverter. The entire diverter tool is capable of being installed in a side-pocket mandrel (12) of the pipeline adjacent the wye-section using such standard oil field equipment as a kickover tool. The entire diverter is also easily removable for servicing using a standard kickover tool. </p> |
