Specialist Petrophysicists

Domain Experts, Eminent Specialists & Best Practice Petrophysicists

We are a Specialist Petrophysics Company with extensive experience working and integrating with other upstream disciplines. Our Principal Petrophysicist Stephen Adams, has been an Independent Consultant since 1994. During that time we have been privileged to be involved in some interesting and challenging projects from all over the world. We have also developed innovative solutions to challenges as necessary. Steve trained as a Physicist before joining the oil industry.


The Petrophysicist Limited has invited a few very experienced Petrophysicists to associate with us. Like our Principal Petrophysicist, Alan Sibbit, Dale Fitz and Tony Kennaird are held in very high regard around the world for their Technical Expertise. We are also working with Colin McPhee on a number of Joint Training course where we both present and assist throughout. These courses have been very well received. Colin McPhee, and Stephen Adams have also collaborated on a number of Projects for Operators since 2019. 

The Petrophysicist Limited has plenty of Specialist Knowledge to help you solve your problems and achieve your Technical and Training goals! More details here, while maps showing our Basins/Areas of experience are below.

Data Science

 Extracting Knowledge or Insights from Data in Various Forms

"Data scientists use their data and analytical ability to find and interpret rich data sources; manage large amounts of data despite hardware, software, and bandwidth constraints; merge data sources; ensure consistency of datasets; create visualizations to aid in understanding data; build mathematical models using the data; and present and communicate the data insights/findings." (from Wikipedia)

Unsurprisingly, that's what Petrophysicists have been doing for years. TPL has focussed on developing these skills and can assist you with your Data Science (and Big Data) needs.

The Book

Saturation-Height is Used In All Static & Dynamic Modelling/Simulations - Get It Right with THE BOOK!

Saturation-Height Modelling for Reservoir Description

By Stephen J. Adams first Published April 2016, new edition dated October 2022

The long awaited book "Saturation-Height Modelling for Reservoir Description" (ISBN 9780473355197) has now been completed and is available for purchase on this page. New edition (dated October 2022) with minor updates available now.

This book is the most complete single source document available anywhere addressing capillary pressure measurements, saturation-height modelling, implementation and interpretation. It also includes detailed explanations and guides to show readers how to create and implement appropriate saturation-height functions. Uncertainty is addressed throughout the volume.

This book will change the way you think about saturation-height modelling. It will show you ways to extract additional information from your interpreted reservoir properties, providing new insights that will both save you money and allow upside to be recognised.

For many petroleum engineers, this book will suffice to replace costly industry training courses on this subject, making its purchase a cost effective choice.

The book is 440 pages in A5 paperback, suitable for your briefcase or bookshelf. Sorry no digital version owing to the current ease with which any DRM can be broken and the book freely distributed.

Industry experience reveals a clear need for improved understanding of capillary pressure measurements, saturation-height modelling and their implementation in reservoir modelling.


Petrophysicists, Geologists and Reservoir Engineers are the primary audience. It will also benefit to anyone wanting to understand the distribution of hydrocarbons in the subsurface, including university students.


These scenarios are covered in detail, including examples using real data. You will also find best practice guidelines in an accessible form.


This book is the product of decades of specialist experience followed by thousands of hours of reading, writing and testing. The value that can be gained will range from a few thousand to billions of dollars.
