The book provides useful explanations on how to perform fit for purpose interpretations of petrophysical data, with emphasis on what the interpreter needs and what is practically possible with real data. Readers are not limited to static reservoir properties for input to volumetrics, as the book also includes applications such as reservoir performance, seismic attribute, geo-mechanics, source rock characterization, and more.
- Principles and practice are given equal emphasis
- Simple models and concepts explain the underlying principles
- Extensive use of contemporary, real-life examples
All sub-surface professionals who are users of petrophysical interpretations. Graduate petroleum engineers and geologists, operations geologists, and drilling engineers

Martin Kennedy
Martin Kennedy is a practicing Petrophysicist now based in Australia. He started work as a Wireline Logging Engineer and has been involved in some aspect of Petrophysics ever since. After leaving the field he spent over twenty years working as a Petrophysicist for the UK Government and three different oil and gas companies before becoming an independent consultant in 2008. He now works for a wide variety of organisations assisting with everything from single well operations to field development and technical assurance. He has worked in most of the major petroleum basins around the world and has covered everything from clean porosity sandstones to fractured basement. Whilst petroleum still takes up the majority of his time, his work increasingly involves so-called New Energy areas like CCUS and Hydrogen. The material in this book and his approach to petrophysical analysis has been shaped by his nearly 40 years in the business. He has a degree in Chemistry from the University of Bristol University and a Ph.D in Electrical Engineering from the University of Edinburgh.
