Title: Communication system for sequential liner hanger setting, release form a running tool and setting a liner top packer
Inventor: Eric Halfman
IPC: E21B47/18
Filed: 2016-11-16
Abstract: 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.
