Torus BOP Introduction


The Torus Annular Blowout Preventer is a unique design in well control technology. Unlike other annular units, the Torus employs no metal fingers in its packing element. This allows the BOP to close around irregular shaped or multiple objects in the well bore as well as over open hole, without damage to delicate equipment such as electric submersible pump cable or fiberglass tubing.

In addition, the Torus has no moving mechanical parts such as pistons and dynamic seals that are easily damaged by foreign material in the closing fluid. The outer packer acts as a diaphragm to transfer the hydraulic pressure to the inner packer which closes the BOP.
