25 - Seismic Models

Seismic Data Acquisition and Processing | Estimated Time : 32 mins

   Watch Promo


This course covers some basic topics concerning seismic data acquisition and processing, and is intended as a primer for non-geophysicists who work on log analysis in support of geophysical projects. You will learn about the various types of seismic acquisition methods, acoustic velocity, and time to depth conversions. Depending on your knowledge of the seismic industry, you may want to run these lectures in the order 25, then 21 thru 24 and save the self-exam in Lecture 25 for the end of your studies on Seismic Petrophysics.


Petrophysicists, log analysts, geophysicists, geologists, reservoir engineers, and university / tech school students who need a refresher on seismic data terminology and basic seismic concepts.


  • Provides basic understanding of seismic data acquisition and processing concepts
  • Provides step-by-step procedures for modeling logs for seismic purposes
  • Provides "computer ready" mathematics
  • Gives insight into log quality problems that affect seismic models


  • Seismic Concepts for Non-Geophysicists
  • Seismic Data Acquisition
  • Seismic Velocity Analysis Techniques
  • Calculating Seismic Velocity From Logs
  • Calculating Interval Velocity From Seismic
  • Time to Depth Conversions
  • Seismic Velocity and Dipping Beds
  • Exercise 25 (Self Exam for Lectures 21 thru 25)

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.
