Instructor: Roger L. Nutt                                                                          5 days

 

Who should attend:

Geologists, Geophysicists, Petroleum Engineers, Petrophysicists, Technicians - even Managers, if they are exposed to (or use) open-hole logs in their daily work.

 

About this course:

This is a slightly simplified version of the Basic well log Interpretation course which Mr. Nutt has successfully taught for many years. This course is ideal for anyone who has no prior knowledge or experience, especially newcomers to the oil industry. The instructor uses clear and easy-to-understand Power-Point slides and loads of practical examples, livened with entertaining anecdotes from a lifetime's experience in the oil-patch. This course will give you the confidence you need to understand and interpret all the basic open-hole logs.

 

Course Content:

 

• How to identify reservoir rocks.
• Invasion profile.
• Why the SP is important, and how to use it.
• Identifying hydrocarbon zones from resistivity logs.
• How the basic logging tools work, and what they measure.
• The common rock types, and how to identify them.
• How to use gamma rays, spectral gamma-rays and the photoelectric effect.
• What porosity is, and how the different kinds of porosity are measured.
• Archie's equation - where it comes from, what it means, and how to use it to calculate water saturation.
• How to handle shaley zones.
• Quick-look and reconnaissance interpretation methods.
• Cross-plot techniques, and some useful short-cuts.

 

What you will learn...

Even if you have never seen a log before, at the end of this one week course you will be able to recognize all the basic logs, know what they are measuring and how to read them, recognize all the common rock types, identify hydrocarbon zones, calculate porosity and water saturations, and even have confidence in your choice of interpretation parameters.
