Claim Text:
1. A method of individually servicing a plurality of zones of a subterranean formation comprising: positioning a work string comprising a first sleeve system and a second sleeve system within a wellbore such that the second sleeve system is uphole relative to the first sleeve system, wherein the first sleeve system comprises a first one or more ports, and wherein the second sleeve system comprises a second one or more ports, communicating an obturator through the work string to the second sleeve system; contacting the obturator with a seat of the second sleeve system; applying pressure to the obturator such that the second sleeve system transitions from an installation mode to a delay mode, wherein fluid communication via the second one or more ports is not allowed when the second sleeve system is in the installation mode and the delay mode; communicating the obturator through the work string to the first sleeve system; contacting the obturator with a seat of the first sleeve system; applying pressure to the obturator such that the first sleeve system transitions from an installation mode to a fully open mode, wherein fluid communication via the first one or more ports is not allowed when the first sleeve system is in the installation mode, and wherein fluid communication via the first one or more ports is allowed when the first sleeve system is in the fully open mode; communicating a servicing fluid via the first one or more ports; after communicating the servicing fluid via the first one or more ports, restricting fluid communication via the first one or more ports; and after restricting fluid communication via the first one or more ports, allowing the second sleeve system to transition from the delay mode to a fully open mode.
