250.401—What must I do to keep wells under control?
You must take necessary precautions to keep wells under control at all times. You must:
(a)
Use the best available and safest drilling technology to monitor and evaluate well conditions and to minimize the potential for the well to flow or kick;
(b)
Have a person onsite during drilling operations who represents your interests and can fulfill your responsibilities;
(c)
Ensure that the toolpusher, operator's representative, or a member of the drilling crew maintains continuous surveillance on the rig floor from the beginning of drilling operations until the well is completed or abandoned, unless you have secured the well with blowout preventers (BOPs), bridge plugs, cement plugs, or packers;
(e)
Use and maintain equipment and materials necessary to ensure the safety and protection of personnel, equipment, natural resources, and the environment.
