This interactive course will introduce you to the fascinating world of petrophysics, the relationship between the rock, the fluid it contains and its interactions, from the downhole response to the actual formation evaluation techniques and procedures.
The course will explore the tools response to different lithologies and will help you understand log readings, applications and limitations. It will instruct you with the basic Petrophysical concepts as well as the log interpretation techniques and procedures for the correct evaluation of well logs on clean and shaly sand formations. This training course will feature:
Discussions on tools physical principles and applications
Tool limitations on different borehole environments
Tips and examples to identify and understand common logging issues
Explanation of petrophysical concepts and techniques for formation evaluation
Application of interpretation methods in several examples and exercises
Course Level: Foundation Duration: 5 days Instructor: Angel Meso
Designed for you, if you are...

A geologist, geophysicist or petrophysicist
A petroleum, reservoir or drilling engineer
In general, any oil & gas industry professional involved in logging data interpretation and validation
How we build your confidence
This training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. The sessions will include visual, auditory and kinesthetic elements to cover the three different learning modalities. The daily sessions will be highly interactive and participative. This involves regular discussion of applications as well as hands-on exercises that will be solved manually and/or using Microsoft Excel.
