Abstract: Methods and systems operate multiple downhole tools in wells based on hydraulic pressures supplied in control lines. The methods and systems pair each of the tools with a manifold enabling selective actuation of each of the tools from a remote location. Some embodiments include between three and twelve manifold and tool pairs configured for control independent from one another with four of the control lines.
