   Watch Promo


This course provides quantitative methods for preparing seismic models and synthetic seismograms from sonic and density logs. You will learn the specialized techniques used to convert depth domain log data into the time domain of the seismic environment, how seismic wavelets are generated, and how they are convolved with the log data to generate synthetic seismograms. Numerous examples and case histories are included.


Petrophysicists, log analysts, geophysicists, geologists, reservoir engineers, and university / tech school students who need to generate log analysis results in aid of seismic modeling, synthetic seismograms, seismic inversion, or AVO models.


  • Provides methods for seismic modeling and creation of synthetic seismograms from well logs
  • Provides "computer ready" mathematics
  • Gives insight into how log analysis can support geophysical models


  • Seismic Modeling Basics
  • Step By Step Procedure for Modeling
  • Integrating the Sonic Log
  • Acoustic Impedance and Reflection Coefficients
  • Calculating Seismic Wavelets
  • Convolution of Wavelet & Reflection Coefficients
  • Case Histories: Synthetic Seismograms
  • Exercise 23

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.
