Course Overview

This course will introduce and familiarise you with the fascinating world of petrophysics, the relationship between the rock, the fluid it holds and its interactions, from the downhole response to the actual formation assessment procedures and techniques.

You will discover and explore the tools response to different lithologies which will help you understand log readings, applications and limitations. It will instruct you with the necessary Petro-physical concepts as well as the log interpretation techniques and procedures for the correct evaluation of well logs on clean and shaly sand formations.

This Zoe course will emphasise and feature the principles and techniques of well log interpretation for oil industry professionals and experts who deal with wireline and/or LWD logs. Advanced interpretation techniques and methods will be deliberated with several examples and exercises involving complex lithology interpretation techniques.
