#$%^&*AU2017219163B220181018.pdf#####ABSTRACT A downhole communication and control system configured for use in a nonsequential order of treating a borehole, the system includes a string having at least three ports including first, second, and third longitudinally spaced ports arranged sequentially in a downhole to uphole 5 manner in the string; at least three frac sleeve systems including first, second, and third frac sleeve systems arranged sequentially in a downhole to uphole manner in the string and arranged to open and close the first, second, and third ports, respectively, each frac sleeve system having self-powered, electronically triggered first and second sleeves; and, communication signals to trigger the first, second, and third frac sleeve systems into moving the first and second sleeves to 10 open and close the ports. Also included is a method of completing downhole operations in a nonsequential order.
