Abstract
Official abstract text for this publication.
A method of servicing a subterranean formation comprising providing a first sleeve system comprising a first one or more ports and being transitionable from a first mode to a second mode and from the second mode to a third mode, and a second sleeve system comprising a second one or more ports and being transitionable from a first mode to a second mode and from the second mode to a third mode, wherein, in the first mode and the second mode, fluid communication via the one or more ports of the first or second sleeve system is restricted, and wherein, in the third mode, fluid may be communicated via the one or more ports of the first or second sleeve system, transitioning the first and second sleeve systems to the second mode, and allowing the first sleeve system to transition from the second mode to the third mode.
