Abstract:
A wellbore servicing apparatus is disclosed that includes a housing having one or more ports, a first sliding sleeve that is movable from a first position to a second position, a second sliding sleeve that is movable from a first position to a second position, a chamber within the housing, and an indicator within the chamber. When the first sliding sleeve is in the first position, the ports are obstructed and the second sliding sleeve is retained in the first position. When the first sliding sleeve is in the second position, the ports are unobstructed and the second sliding sleeve is not retained in the first position. When the second sliding sleeve is in the first position, the indicator is retained within the chamber. When the second sliding sleeve is in the second position, the indicator is not retained in the chamber.
