Abstract:

A variable ram assembly for use in a blowout preventer (BOP) stack includes a packer element. The packer element includes an elastomeric body having a contact surface configured with a curved recess for sealing engaging a tubular. At least a portion of the body adjacent the contact surface is reinforced to define a reinforced area. The reinforced area exerts a restraining force to prevent extrusion of the elastomeric body when it is forced against the tubular. The reinforced area is integrally formed with the body using a molding process.
