Abstract:
1. An activatable wellbore servicing apparatus, comprising; a housing, the housing generally defining an axial flowbore and comprising one or more ports; a first sliding sleeve; a second sliding sleeve, wherein at least a portion of the first sliding sleeve is telescopically positioned within at least a portion of the second sliding sleeve, wherein the second sliding sleeve is movable, relative to the housing from (a) a first position in which the second sliding sleeve obstructs fluid communication from the axial flowbore to an exterior of the housing via the one or more ports of the housing to (b) a second position in which the second sliding sleeve allows fluid communication from the axial flowbore to the exterior of the housing via the one or more ports of the housing, and wherein the first sliding sleeve is movable relative to the housing from (a) a first position in which the first sliding sleeve does not allow a fluid pressure applied to the axial flowbore to move the second sliding sleeve from the first position to the second position to (b) a second position in which the first sliding sleeve allows a fluid pressure applied to the axial flowbore to move the second sliding sleeve from the first position to the second position; and an expandable seat.
