Dipmeter and Image Log Data Acquisition and Processing | Estimated Time : 1 hr

   Watch Promo


This course covers the topics needed to understand dipmeter and image log data acquisition and processing. You will learn how processing parameters affect dip results and how to select and quality control parameters to obtain dip angles that are meaningful in a particular geological environment. You will also learn the specialized knowledge needed to calculate dip rotation, true vertical depth, true stratigraphic thickness, and more. Illustrated with numerous examples specific to each topic.


Petrophysicists, log analysts, geophysicists, geologists, reservoir engineers, and university / tech school students who wish to understand the wealth of useful information buried in dipmeter and image logs, especially those hidden away unused in existing well files.

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.
