Abstract
An annular blowout preventer includes a housing, an annular piston positioned within the housing, and an annular packer positioned within the housing. The annular blowout preventer also includes at least one radially-extending conduit disposed in the annular piston, the annular packer, or a plate positioned axially between the annular piston and the annular packer. The radially-extending conduit is configured to enable a fluid to flow from a central bore to an annular space between the annular packer and the housing when the annular blowout preventer is in a closed position.
