ABSTRACT:
A cavity positioning tool includes a housing adapted to be coupled to a downhole string. The cavity positioning tool includes at least one blunt arm pivotally coupled to the housing. Each blunt arm is configured to contact a surface of the cavity to position the tool in the cavity. The cavity positioning tool also includes a piston slidably disposed within the housing. The piston is operable to engage each blunt arm. The piston is also operable to receive an axial force operable to slide the piston relative to the housing. The sliding of the piston extends each blunt arm radially outward relative to the housing from a retracted position.
