High expansion centralizer

Abstract

A system and method of centralizing a tool. The centralizer has a mandrel with a static housing and a dynamic housing positioned about the mandrel. A plurality of V segments, each V segment coupled to the static housing at a first end and the dynamic housing at a second end and shiftable from an undeployed position to a deployed position to centralize the tool. A piston assembly operable to shift the dynamic housing to shift the plurality of V segments from the undeployed position to the deployed position, a retention mechanism operable to prevent the plurality of V segments from shifting from the deployed position to the undeployed position. A flexible sleeve on the outer surface of the plurality of V segments that contacts the wellbore when the V segments are actuated.
