Methods for Evaluating Igneous and Metamorphic Reservoir Rocks | Estimated Length : 40 mins

   Watch Promo


This course covers visual and numerical log analysis methods for evaluating igneous and metamorphic reservoir rocks. You will learn how to handle the difference between minerals and, which are what logs see, and rock types, which are what geologists see in the microscope. Specialized knowledge is required to analyze logs in this unconventional environment. Crossplots and examples specific to this environment are provided.


Petrophysicists, log analysts, geologists, reservoir engineers, and university / tech school students who wish to broaden their exposure to unconventional uses of well logs.


  • Provides insights into a range of unconventional reservoir types
  • Provides step-by-step procedures for analysis
  • Provides "computer ready" mathematics
  • Answer oriented results, with quality control guided by core assays


  • Igneous and Metamorphic Basics
  • Metamorphic Rocks
  • Igneous Rocks
  • Metamorphic Sand / Granite Example
  • Porous Fractured Granite Example

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.
