This program is aimed at people who are in critical well control positions during well intervention operations. Participants must fulfill the prerequisite requirements of this course having IWCF level 3 Drilling certificate. The course covers topics such as well control methods and influx characteristics. Shut-in procedure is also discussed.
Upon successful completion of this course, the delegates will be able to:
- To be able to identify the accountabilities of program signatories
- To know the causes and effects of unplanned inflow
- To be able to recognize potential causes of losses
- To be able to define gas migration
- To describe how the lubricates and bleed methods can be applied
- To detect a possible blockage anywhere in the well
