Blow-out Prevention Equipment and Procedures
A Blowout Preventer (BOP) is one or more valves installed at the wellhead to prevent the escape of pressure either in the annular space between the casing and the drill pipe or in open hole (for example, hole with no drill pipe) during drilling or completion operations. BOP systems and system components should be designed, installed, used, maintained, and tested to assure well control as per applicable applications.
Equipment, including accumulators, should be operational at all times during drilling operations.
Key items in reference to BOP equipment:
- The BOP stack should be:
- properly certified
- shop serviced
- shell-tested every 3 years.
- Equipment, including accumulators, should be operational at all times during drilling operations. Required checks should be completed on schedule and documented as required by BSEE.
- Blowout drills should be performed and recorded prior to drilling out any casing.
- Well-control drills should be performed and documented by each drilling crew every 7 days, or as needed, to ensure proficiency with the operation, as required by BSEE.
