DESIGNED FOR YOU, IF YOU ARE...

A Geologists, Reservoir engineer, Geophysicists, Petrophysicists, Geomodellers, Young subsurface professionals

​

HOW WE BUILD YOUR CONFIDENCE

This course will utilise a variety of examples to ensure an in-depth learning and understanding for the petrophysical evaluation techniques. Some discussions of applications as well as exercises. The course will be delivered through a power point presentation. The participants will have access to the printed course materials and the examples they will have access to during the course.

​

THE BENEFITS FROM ATTENDING

By the end of the course, you will assured of understanding:

   • Physical principles of main open hole logging tools

• Applying basic quality control techniques to validate logging data

• Main applications and limitations of the different tool readings

• Performing a quick qualitative interpretation to determine possible interest zones
