Low field Nuclear Magnetic Resonance (NMR) is a unique petrophysical tool that has been gaining significant exposure as a tool for understanding the properties of petroleum reservoirs.  NMR tools and measurements are now commonly available to the Industry, in the form of both bench top (laboratory) and field (logging) applications.  NMR tests are non-destructive, and can yield a tremendous wealth of information about both the reservoir and the reservoir fluids, all in a single measurement.  This course is designed to provide participants with the necessary tools to understand how NMR works, and how to interpret spectra in different reservoir systems.  This is a very practical and pragmatic course, and is very focused on using examples and case studies to demonstrate concepts.  The goal of this course is for participants to come away with an understanding of how to interpret NMR spectra on their own.

This course will be taught in the form of lectures with example problems dispersed throughout, which are designed to help course participants to internalize and understand the principles being taught.  Participants are encouraged to bring laptop computers with Excel, which will be needed for some of the problems.


    DAY 1

    Introduction to NMR & review of NMR basics

  • Explanation of what NMR measurements are
  • NMR theory – explanation of the acquisition parameters and how to identify if NMR tools are using correct parameters for a given reservoir

    Dr. Kantzas, P. Eng., founded the Tomographic Imaging & Porous Media Laboratory in 1994. A professor from the University of Calgary, Dr. Kantzas has tremendous experience in leading advanced research of porous media, primarily dealing with petroleum reservoir engineering issues. Expert in Tomographic Imaging, Porous Media Physics and Magnetic Resonance Sensor Technology, Dr. Kantzas has led a large research team at the University of Calgary previously under a Canada Research Chair Program and currently under an NSERC/AITF Industrial Research Chair in Fundamentals of Unconventional Resources (FUR).

     Dr. Jon Bryan, P. Eng., did his MSc and PhD degrees at the University of Calgary under Dr. Kantzas’ supervision.  He has been a frequent collaborator in the Canada Research Chair and in Dr. Kantzas’ NSERC Chair in Unconventional Resources.  Jon has expertise in petrophysics and enhanced oil recovery, and manages many of the service and core flooding projects at PERM Inc.

    Dr. Sergey Kryuchkov manages R&D at PERM Inc. and has helped bring several NMR technologies to market such as field-type Magnetic Resonance Water Cut & Multiphase Meters.  Areas of expertise include Physics of Flow in Porous Media, CFD, Reactive Multiphase Flows, and NMR applications in Oil & Gas.


This was a fantastic course that begins with the fundamentals of NMRI and builds your knowledge base slide by slide in a logical and well-taught manner.  The real world examples and hands on calculations improve your grasp of the concepts and show the limitations and uncertainties of NMR technology and state-of-the-art techniques.  I recommend this course for laboratory and field-based NMR users alike.
