5 days FOR/UBDE
- Drilling and mud engineers, superintendents and supervisors, and all professionals involved in well planning and operation.
- This course provides a comprehensive and practical knowledge of non-conventional techniques used in advanced drilling and completion processes to enhance drilling performance and oil recovery.
- Upon completion of the course, participants will be able to:
- deal with issues of narrow pore/fracture pressure gradient windows, lost circulation, abnormal pressures, kick/loss situations,
- drill wells in depleted reservoirs,
- acquire basic concepts of managed and underbalanced pressure drilling,
- review various managed pressure drilling methods and equipment,
- identify typical situations calling for managed pressure drilling and assess potential benefit,
- review typical applications, equipment and operation of underbalanced drilling.
- No prerequisites for this course.
Ways and means
