Well Control in Case of Offshore Blowout: Capping on the Sea Floor, Blowout Risk of Subsea Oil Production

摘要

Single wells with wet production tree are easier to cap than other wells and also easier for underwater collection, and less likely to be hit by falling objects. Blowouts from completed subsea wells are likely to produce very large oil spills. It is recommended to strengthen the underwater work capability, but not to build special underwater capping equipment at present.
