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 a rib, and a foot pivotally coupled to the rib, and an elastomeric body coupled to the plurality of inserts and including an inner surface, wherein the foot is configured to resist deformation of the elastomeric body in response to the blowout preventer actuating from a first position to a second position.

Blowout preventer apparatus and method

A blowout preventer is disclosed that includes a housing defining a central passage. The central passage is configured to receive a tubular string therethrough. In addition, the blowout preventer includes a packing element disposed in the central passage. The packing element includes an elastomeric member, and a rigid insert mounted to the elastomeric member. The insert includes an extendable tip assembly configured to extend a movable member away from the rigid insert.

Blowout preventer packing assembly

A wiper () for a blowout preventer having an adapter ring () and a piston () slideable relative to the adapter ring along an interface can include a base () adapted to couple the wiper to the adapter ring and a head () coupled to the base. The head can include a first portion adapted to bridge the interface and contact the piston and a second portion adapted to contact the adapter ring and support the first portion. The second portion of the head can be adapted to at least partially resist rotation of the wiper. A blowout preventer can include one or more wipers as shown and described.
