A bottom hole assembly supports a diverter for landing in an existing multilateral junction. Once landed set down weight allows the BHA to progress through the diverter opening into a main bore, for example. A protective sleeve for the seal assembly lands on a shoulder above the targeted seal bore. Further advancing of the BHA moves the seal assembly out of the protective sleeve that has landed on the shoulder by the polished bore. Once the seals are in position in the bore a treatment can be accomplished. On picking up the seal assembly retracts into the protective sleeve and the BHA engages the diverter to bring the BHA and the diverter out of the borehole at the same time.

A communication system for sequential operation of subterranean tools involves flow based signals that are picked up with an acoustic receiver at a master controller, which then signals one or more slave controllers that operate tools and communicate back to the master controller that the subject tool has been operated. Sensors associated with the control system gather data downloaded when the master controller is pulled out of the hole. The system can be used to set a liner hanger and release a running tool and communicate that the liner hanger and running tool has activated. This can be confirmed with setting down weight and noting the running string going from tension to compression with a load cell or by translating the running string within the hole. The liner top packer can be set with a flow based signal to the master controller which is then removed with the running string.
