Introduction To Basic Well Log Analysis Series

Introduction To Basic Well Log Analysis Series

The Society of Petrophysicists and Well Log Analysts (SPWLA) is pleased to offer a 6-part webinar series, Introduction to Basic Well Log Analysis is for non-petrophysicist and beginners in petrophysics and well log analysis. The goal of the sessions is to present petrophysical technology to those who have been exposed to petrophysical data and results, or to those who use those data and results, but who haven’t studied the entire range of common openhole measurements.


Bonus: If you register for the first 5 classes you will get the 6th (last) class FREE.

Online classes via webinar - A link to the webinar will be sent to your email a few days before webinar starts.

Instructor: Dan Krygowski, a Senior Petrophysical Advisor with The Discovery Group. 

Dan Krygowski is a Senior Petrophysical Advisor with The Discovery Group, which he joined in late 2006. He has over 35 years of experience in the art and science of petrophysics, and in the development and design of petrophysical software. Dan earned a B.A. in Physics from the State University of New York at Geneseo. After earning M.S. and Ph.D. degrees in geophysics from the Colorado School of Mines (with a focus on petrophysics), he has worked for several production companies, one software company, and two oil & gas consultancies, in technical and management positions.

Since the late Cretaceous, Dan has taught the AAPG Basic Well Log Analysis course annually with Dr. George Asquith of Texas Tech University, and for the last several years, with the addition of Rick Lewis, of Schlumberger. Dan also teaches Basic Openhole Log Interpretation, a similar, but shorter course, and Petrophysics Elements, a much longer, lower intensity course meant to delve deeper into petrophysical information and methods as part of participants’ regular job duties.

In 2004, AAPG published George and Dan’s book, Basic Well Log Analysis, a second edition of George’s 1983 similarly-named book which was one of the AAPG’s all-time best-selling publications. The 2004 edition has also become an AAPG best-seller.

Dan is a member of the Society of Petrophysicists and Well Log Analysts (SPWLA), AAPG, SPE, SEG, Denver Well Logging Society (DWLS), and Rocky Mountain Association of Geologists (RMAG).

This group of resistivity measurements: Induction Logs, Laterologs, and Electric Logs, are the last that we need to determine fluid saturation. We’ll consider the concepts involved in resistivity, and address how and where resistivity is measured. We’ll briefly consider Archie’s saturation equation as a lead-in to the methods, numerical and graphical, that are used to determine saturations.
8:00 AM - 9:30 AM

In this final session we look at the final steps in the workflow; determining formation fluid content through the addition of resistivity measurements to our previous measurements. We’ll consider pattern recognition (graphical) techniques which were developed to determine saturations without calculations, and which are now used to determine calculation parameters in the equations that we previously avoided. One goal of this last session is to entice you to spend a week becoming immersed in petrophysics, but again only in the basics
