Abstract

A method of hydraulically actuating downhole equipment includes supplying pressure P(z) to a downhole network comprising tools T(n), tool T(x), control lines C(z), and control lines Y(z), wherein n and z are integers, and x=n+1, wherein a pressure P(z) is applied to tool T(n) using at least one control line C(z) in hydraulic communication with tool T(n); applying pressure P(z) to a hydraulically movable portion of tool T(n), wherein pressure P(z) to tool T(n) is not high enough to independently activate tool T(x); and applying each pressure P(z) to a hydraulically movable portion of tool T(x), wherein tool T(x) is only activated when all of pressures P(z) are simultaneously applied to the hydraulically movable portion of tool T(x), and wherein tool T(x) is only activated when each pressure P(z) is at least at a preset value PV(z).
