A Hydril is one of the types of blowout preventers (BOP’s) that is a specialised valve which is used to prevent blowout while monitoring, controlling, or sealing oil and gas wells. The annular blowout preventer is known as Hydril, which is named after one of the manufacturers of the device. (e.g., GE Hydril Line of Products means the GE O&G Hydril Annular Blowout Preventer, including, without limitation, the hydraulic piston, the packing unit, the elastomer compounds and the valves associated therewith.)
