4 1/2 days
To provide delegates with an understanding of well control methods relating to well intervention operations.
At the end of the course delegates should be able to:
Identify completion types, equipment functions and industry practices
Identify barrier systems and know the terminology
Identify well control methods
Identify solutions to various well control problems
Determine if well control equipment is fit for purpose
Design a well kill plan for a production well and generate a kill graph
Discuss production well kill problems and recommend appropriate solutions
