4. Supervisor Level Overview The purpose of the core curriculum is to identify a body of knowledge and a set of job skills that can be used to provide well control skills for drilling operations.

This curriculum incorporates both surface and subsea topics. The majority of the topics are relevant to both surface and subsea operations. Those topics specific to subsea are in a BLUE font. To assist the user, all Subsea topics have been extracted into Section 4.14.

Recommended Attendees:

WCI recommend the following Job Positions attend the Supervisor Level course:

• Wellsite Supervisors, Company men and assistants • MPD/UBD Wellsite supervisors • Office-based drilling supervisors/superintendent (not involved with well design approval) • Office-based rig, drilling manager • OIM for mobile offshore drilling units • Rig Manager (shore-based/superintendent (land)) • Rig Superintendent offshore (most senior offshore leader for drill crew, may be the OIM) • Toolpushers

Note:

• Blue Text = Subsea • Black Text = Common to Surface and Subsea
