Downhole control system having a versatile manifold and method for use of same
Abstract:
A downhole control system for actuating hydraulically controlled devices positioned in a well. The system includes a first set of N hydraulically controlled devices positioned in the well and a second set of at least one hydraulically controlled device positioned in the well. A common control line is ported to a first side of each of the hydraulically controlled devices in the first set. N control lines are each ported to a second side of one of the hydraulically controlled devices in the first set. A first control line of the N control lines is ported to a first side of a first hydraulically controlled device of the second set and a second control line of the N control lines is ported to a second side of the first hydraulically controlled device of the second set, such that N+1 control lines are operable to actuate N+1 hydraulically controlled devices.
