IOGP Well Control Incident Lesson Sharing

The International Association of Oil & Gas Producers (IOGP) Well Control Incident lesson sharing system was established as a means of notifying fellow IOGP members and the wider community of the lessons learned from well control incidents and near misses. The sharing of these lessons will help to promote learning and avoid the repetition of similar errors. The result will move the industry to a higher level of well control safety. IOGP is grateful for all contributions and the continued support of the Well Control Incident Database reporting system.
