This course is the first step into the adventure of Petrophysics. It is the introduction part of the series of 39 courses developed by Ross Crain covering Practical Integrated Petrophysical Analysis .

Everyone in the oil and gas industry, from novice geologist to the President, should know the basics of petrophysics. These lectures have been time-tested in major and independent oil companies, government agencies, consulting firms, oilfield service companies, and the university classroom.

Managers, geologists, log analysts, geophysicists, reservoir engineers, completion engineers, stimulation engineers, and university / tech school students who wish to become proficient in petrophysical analysis or who need to manage or make use of petrophysical results will benefit from this course.


  • Provides foundation for all future Lectures in in this series
  • Provides basic definitions of important terms
  • Gives an overview of the broad topic of well logs and petrophysics


  • What is Integrated Petrophysics?
  • What is a Log?
  • Recording Logs at the Wellsite
  • What Do Logs Look Like?
  • What Logs Are Available?
  • What Answers Can We Get From Logs?
  • Uses of Log Analysis Answers
  • Some Real World Examples

An open mind and a desire to excel in the oil and gas industry.
Basic understanding of geology is helpful but not required.

Ross Crain
Ross Crain

Mr Crain is a Professional Engineer with over 35 years of experience in reservoir description, petrophysical analysis, and management. He has been a specialist in the integration of well log analysis and petrophysics with geophysical, geological, engineering, and simulation phases of oil and gas exploration and exploitation, with widespread Canadian and Overseas experience. He has an Engineering degree from McGill University in Montreal and is a registered engineer in Alberta.

He wrote “The Log Analysis Handbook”, and he offers seminars, mentoring, or petrophysical consulting to oil companies, government agencies, and to consulting service companies around the world. Projects have spanned conventional and unconventional reservoirs in more than 40 countries.

Ross is credited with the invention of the first desktop log analysis system (LOG/MATE) in 1976, 5 years before IBM invented the PC. He continues to advise and train people on software design, implementation, and training. For his consulting practice, he uses his own proprietary software (META/LOG), and is familiar with most commercial systems.

He has won Best Paper Awards from CWLS and CSEG and has authored more than 30 technical papers. Mr Crain was installed as an Honorary Member of the Canadian Well Logging Society for his contributions to the science of well log analysis.

Ross's current interest is development of practical solutions for petrophysical analysis of all forms of unconventional reservoirs, determination of accurate mechanical properties of rocks for stimulation design, mentoring of both novices and experienced petrophysicists.

"I so appreciate your material because of how much I am learning from you about logs. So much better than my MSPE courses because every page is about real world application." J.P., Oklahoma

"Thank you so much for your contribution for life." N.V., Viet Nam

"Thank you for your considered effort over the long term wrt to educating the wider global O&G industry. Your are a credit to our industry - Thank you."
J.R., Perth

"I wanted to thank you for putting together such a great petrophysical reference for everyone on the internet to use. Your material solidified my knowledge on many petrophysical concepts, including shaly sand phie and sw. My team also utilized your website to become better petroleum geologists." R.H., Montana

"I really would like to thank you for your generosity. It is really outstanding, and one of the most integrated resources for Petrophysics that I have ever come across.
I decided to specialize in rock physics, and many thanks to you and your effort." M.M., Egypt

"I'm an ardent fan of yours. By profession I'm Petrophysicist. I usually work with ElanPlus as my analysis tool. But I always do hand calculation first. And whenever I teach new persons I insist that he/she should visit your site and learn petrophysics the way it should be learnt. To me you are the Richard Feynman in Petrophysics." Shishir
