This course continues coverage of basic petrophysical analysis with a review of logs used to determine resistivity or correlation of rock formations.
You will learn the basic physics and operating principle behind each tool, the common log displays, and limitations of each tool.
Tools are described in their generic form and specific service companies may offer variations on the basic design concepts.
Knowledge of tool theory is especially important when things don't appear to be "going right". Many log analyses fail because the tool's limitations or operating environment were exceeded. You need to know when and where the data will be valid.
Who Should take this course:
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.
Basic understanding of quantitative Petrophysics or equivalent background.
Basic understanding of high school level physics is helpful but not required.

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.

"Your material has
proven invaluable to me in a number of projects
in the Permian Basin and Arkoma Basin.
Everything is so well organized and thorough
that I am able to resolve petrophysical
questions much more quickly than digging through
my old books and files! Thanks again for your
leadership in this area." C.K., Texas
“My thanks to you. Your material is a wealth of great information and tools. It's clearly a "labor of love" for you and a treasure for any of us lucky enough to find it.”
