1 - Introduction to Primary Well Control

Introduction to Primary Well ControlThis Introduction to Primary Well Control teaches us that safety is always the primary concern. Here we cover the purpose of primary well control and see how potential hazards are avoided. We look at how well control is maintained with a column of drilling fluid providing the correct hydrostatic pressure. Key components of the system that conditions and pressurises the mud for circulating downhole are explained. We also explore how casing and wellhead systems provide support for the formation and form a conduit for fluids to return to the surface during drilling operations.

Approximate duration: 20 minutes.

By the end of this module you should be able to:

  • Explain the fundamentals of pressure control and the methods used in maintaining primary well control
  • Give examples of the potential hazards associated with the loss of primary well control
  • Recognise the basic terminology used in primary well control
