Abstract:
A control system for a plurality of devices including a plurality of devices in at least one group. A first control line is in operable communication with the plurality of devices. A second control line in operable communication with the at least one group. A step-advance mechanism is in operable communication with each of the plurality of the devices, each mechanism being distinct from each other mechanism within the group of devices. Further disclosed herein is a method for reducing the number of control lines needed to control a plurality of downhole devices including supplying a first control line in operable communication with a plurality of devices including at least one group of devices and supplying a second control line in operable communication with the at least one group.
