ABOUT COURSE
This course is an advanced drilling course designed to provide training in the application of drilling to effect efficient and economical drilling practices as well as solutions to drilling problems encountered during well planning and drilling operations. Problems will be solved using computers.
BENEFITS OF THE COURSE
At the conclusion of the course, participants will be able to do the following:
- Understand excellent drilling practices
- Understand drilling problems and how to mitigate or solve them
- Perform pre- and post-drilling analysis, and drilling cost analysis
- Minimize drilling costs and maximize return on investment
WHO SHOULD ATTEND
Senior Drilling Engineers, Geologists, Drilling Supervisors, Managers, Drilling Contractor and Service Personnel
