ABSTRACT:
A system and method is provided for integrated control of multiple well tools. Predetermined pressure levels are utilized in independently actuating specific well tools from a plurality of well tools. The number of well tools independently controlled may be greater than the number of fluid control lines that cooperate with the well tools to control tool actuation.
