WB-5: Well integrity – Advanced definition of well barriers
Give the participants the reasoning for how to prepare well barrier schematics for
special well activity situations and produce these in a consistent manner. Following
the course the participant shall be able to prepare well barrier schematics with
appropriate qualification and monitoring descriptions.
Brief description of the course
The course gives the participants an advanced approach into how to draw and
establish appropriate well barrier envelopes for more complex well situations.
We will use the Wellbarrier Illustration Tool to make examples, but the benefit of the
course and the principles can be used with any type of drawing platform.
Personnel directly responsible and or involved in well Integrity should have the recommended training. Examples of
who may be required to have this training are as follows:
- Drilling/completion/intervention engineers (including drilling supervisor and drilling superintendent);
It is recommended that management responsible for well integrity should be trained.
