Abstract: A seal for a blind shear ram is configured to extend between a first carrier and a second carrier of the blind shear ram. The seal includes a curved portion and an elastic layer extending through the curved portion. The elastic layer is configured to contact at least one of the first carrier and the second carrier to seal a wellbore when the first carrier and the second carrier are in a closed position. The elastic layer has a first elasticity. The seal also includes an anti-extrusion structure coupled to the elastic layer. The anti-extrusion structure extends through the curved portion. The anti-extrusion structure has a second elasticity less than the first elasticity. The anti-extrusion structure defines a plurality of slits to facilitate the anti-extrusion structure extending through the curved portion.

Abstract: A seal for a blind shear ram is configured to extend between a first carrier and a second carrier of the blind shear ram. The seal includes an outer layer configured to contact at least one of the first carrier and the second carrier to seal a wellbore when the blind shear ram is in a closed position. The outer layer has a first stiffness. The seal also includes an inner layer spaced from the outer layer. The inner layer has a second stiffness. The seal further includes an anti-extrusion structure extending between the inner layer and the outer layer. The anti-extrusion structure has a third stiffness greater than the first stiffness and the second stiffness. The outer layer covers the anti-extrusion structure.

The anti-extrusion structure includes a plurality of ribs spaced along a longitudinal axis of the anti-extrusion structure. The plurality of ribs define a plurality of spaces configured to receive portions of the elastic layer.
