description The present disclosure generally relates to an annular blowout preventer ("BOP") apparatus for sealing a wellbore. In particular, the annular BOP includes a body comprising a vertical bore extending therethrough, an upper packing element located in the body, a lower packing element located in the body and spaced axially from the upper packing element, and a piston configured to move the upper and lower packing elements radially with respect to the vertical bore. The annular BOP provides for bi-directional sealing across the annular BOP. In other embodiments, the annular BOP may include only a single packing element configured to provide for bi-directional sealing across the annular BOP.
