Abstract
A downhole tubular system including a tubular defining a wall having an inner radial surface and an outer radial surface, the outer radial surface having a circumferential channel formed therein extending 360 degrees defining a punch portion, the inner radial surface defining an inner bore; a sleeve attachable around the tubular; and at least a portion of a control fluid chamber passageway defined between the sleeve and the outer radial surface, the wall occluding fluidic communication between the control line passageway and the inner bore until the punch portion has been punctured.
