Abstract: An annular elastomeric packer for a blowout preventer includes a plurality of circumferentially spaced inserts, wherein at least one of the plurality of inserts includes an upper flange extending between a radially inner end and a radially outer end, a lower flange extending between a radially inner end and a radially outer end, and a rib extending between the upper flange and the lower flange, wherein the upper flange includes an upper surface disposed at an acute angle relative a longitudinal axis of the elastomeric packer, and an elastomeric body coupled to the plurality of inserts and including an inner sealing surface.

Abstract: An annular elastomeric packer for a blowout preventer includes a first insert including an upper flange extending between a radially inner end and a radially outer end, a lower flange extending between a radially inner end and a radially outer end, and a rib extending between the upper flange and the lower flange, wherein the rib includes a length extending between an upper end and a lower end of the rib, a second insert including an upper flange extending between a radially inner end and a radially outer end, a lower flange extending between a radially inner end and a radially outer end, and a rib extending between the upper flange and lower flange, wherein the rib includes a length extending between an upper end and a lower end of the rib, an elastomeric body coupled to the first insert and the second insert, and including an inner sealing surface.

Abstract: A blowout preventer (“BOP”) includes a housing comprising a vertical bore extending through the housing and a packer assembly movably positioned within the housing and configured to form a seal within the housing. The packer assembly includes an elastomeric body comprising an elastomeric material and inserts positioned within the elastomeric body and in parallel alignment with respect to each other.

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.
