5 days FOR/LOGFIE
- Young engineers and supervisors, toolpushers with some experience in drilling.
- This course provides a thorough, practical knowledge of openhole logging, mud logging and fishing while drilling.
- Upon completion of the course, participants will be able to:
- understand, assess and interpret measurements made while drilling,
- learn about techniques and equipment used for coring during drilling operations,
- understand how to prevent kicks and drilling problems with mud logging data analysis,
- understand wireline and LWD technology with regard to log data analysis,
- appreciate the geoscientists’ work in a quick-look log analysis at the rig site.
- No prerequisites for this course.
Ways and means
- Application to a real case (project) for the participants in the “Drilling and Completion Engineering” training course (E-412C).
* Public holidays: the course schedule will be adapted to cover all content.
