摘要:
An expansion device (48) for a wellbore servicing tool (10), comprising a wedge (52) comprising a frusto-conical wall having a tip end (88), the wedge being configured coaxially along a central axis, a plurality of slip segments (50), each slip segment comprising an inner surface having an incline surface, and at least one bridge (94) joining each of the incline surfaces to the frusto conical wall. A method of operating a wellbore servicing tool, comprising longitudinally compressing an expansion device along a central axis, upon sufficient compression, separating plural slip segments from a wedge, moving the wedge relative to the slip segments, upon sufficient movement of the wedge relative to the slip segments, separating at least two slip segments from each other.
