Abstract

See full text

An annular blowout preventer includes a housing, an annular packer positioned within the housing, and an annular piston assembly positioned within the housing. An annular contacting surface of the annular piston is configured to contact the annular packer while the annular blowout preventer is in the open position. The annular blowout preventer also includes a plurality of inserts extending axially through the annular packer and arranged circumferentially within the annular packer. The annular piston is configured to drive the annular packer in an axial direction within the housing, thereby compressing the annular packer, causing the plurality of inserts to rotate radially inwardly, and moving the annular blowout preventer from the open position to a closed position.
