Abstract: A divertor tool is disclosed for diverting a pump-down tool (PDT) along various branches of a pipeline. The diverter includes a flapper to redirect the PDT along an alternate conduit of a wye-section of the pipeline. The flapper is hydraulically operated by an actuation chamber at the lower end of the diverter. The entire diverter tool is capable of being installed in a side-pocket mandrel 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.
