Annular BOP

Annular BOP is an important part of well control equipment. It mainly applies to control wellhead pressure during the drilling, workover operations, formation testing, etc., to prevent well blowout effectively and realise safe construction.

Annular BOP shall be equipped with a hydraulic control system. It is usually used with ram BOP and also independently.

Annular BOPs are a critical component of onshore and offshore exploration. They provide a pressure barrier by sealing around tubular goods, like drill pipes, during drilling operations to ensure optimal safety whenever a problem arises.
