Well Control - WCEC for Surface Rigs




The Well Control Equipment Course (WCEC) is an intermediate well control equipment course and has been specially developed for drilling personnel wishing to gain basic overall skills in well control on surface rigs.


Lloyd’s Register Energy – Drilling, a global leader in providing knowledge, expertise and high quality training services throughout the drilling industry, offers an extensive training programme focused on developing the technical skills and abilities of toolpushers, drillers, assistant drillers and mechanics who are involved in operating or maintaining well control equipment on surface rigs.


Our well control equipment training accommodates all experience and skill levels. All courses in this curriculum are IADC accredited and tailor-made for personnel seeking additional professional training to perform correct and safe operations involving well control equipment on surface drilling rigs.


Who should attend?

This course is intended for personnel involved in drilling operations and working with well control equipment on land rigs, platform rigs and jack-up rigs who want to improve their knowledge. It is recommended in particular to:

  • Drilling Supervisors
  • Drilling Engineers
  • Drilling Managers
  • Toolpushers
  • Maintenance Supervisors
  • (Assistant) Drillers
  • (Assistant) Mechanics



Upon completion of the course, candidates are able to:

  • Describe and explain the main components of well control equipment, including:
  • Ram-type BOPs
  • Annular-type BOPs
  • BOP-installed gate valves
  • Choke and kill manifold
  • Conventional BOP control systems
  • Diverter systems
  • Well control equipment mathematics

Explain the implication of standards (API, ASME, etc.) for maintenance, inspection and function and pressure testing of well control equipment


Course Content

The topics covered during this course include:

  • The function, operation, inspection and the most frequent problems of
    • ram preventers and locking systems
    • shear ram calculations
    • annular preventers
    • BOP gate valves
    • choke and kill manifolds
    • hydraulic control units
    • diverter systems
    • well control equipment mathematics
  • Norms and standards used in the drilling industry (such as API) and their implication for well control equipment
  • Analysis of the configuration and testing of choke and kill manifold
  • Safe working procedures and requirements for pressure testing of the BOP equipment
  • Recognizing symptoms that indicate malfunctions and the necessity of inspection, maintenance or repair of well control equipment



The 5-day course is based on interactive classes with ample time for group participation and discussion. It also includes:

  • Videos to explain operational and maintenance procedures
  • An entry test to evaluate attendees’ knowledge prior to the start of classroom sessions
  • A final exam at the end of the course, with a minimum passing score of 70%
