Abstract
A novel method was introduced by Peeters & Holmes to calculate cation exchange capacities in shaly sand reservoirs using dry clay parameters. This method avoids the use of log readings in adjacent shale layers, and achieves more accurate results. However, a limitation of this method is that the clay type should be known either from cores and sidewall samples. This study demonstrates that clay types can be derived from the cross-plot of the apparent matrix density vs. the apparent volumetrically weighted photo-electric effect, provided the neutron log porosity is corrected for the hydrogen in the crystal lattice. This method is also promising for non-conventional reservoirs to pin point the producing geological facies.
Speaker Biography
Max Peeters is the Honorary consul emeritus for The Netherlands, and host for open space parks. Before that taught petrophysical courses for Petro-Skills, and was from 1998 to 2007 professor of Borehole Geophysics and Petrophysics at the Colorado School of Mines. From 1992 to 1998 he was a professor of Petrophysics at the University of Technology in Delft, and Petrophysical Advisor in Shell Research, both in The Netherlands. Peeters received a MSc in Physics of Delft University of Technology in 1968, followed by two years lecturing at the Royal Dutch Navy Academy. In 1970 he joined Shell International and worked as Petroleum Engineer and Chief Petrophysicist in Australia, England, Brunei, and California. In 1988 he returned to The Netherlands where he was in charge of Shell’s global Formation Evaluation team and headed a Petroleum Engineering team for the development of business opportunities in the former Soviet Union. Max Peeters founded and directed the Center for Petrophysics at the Colorado School of Mines and was one of the editors of the Petroleum Geoscience and Geophysical Prospecting Journals. In June 1996 he received the Distinguished Technical Achievement Award from the Society of Professional Well Log Analysts (SPWLA), and in 2003 a Technical Advancement Award from the Colorado School of Mines. Max Peeters was a visiting professor at Curtin University in Perth Australia in the fall of 2002, and a distinguished lecturer for the SPWLA in 2002-2003. He has published over 25 papers on petrophysical subjects and holds two patents for wireline logging tools.

From the President
Patricia Rodrigues
April is getting closer and our VP of technology is getting the final touches for what promises to be an exciting agenda on Horizontal Petrophysics for our Spring workshop. Last year the workshop was a complete sold out. The registration will be out soon, so make sure to check our website often (http://dwls.spwla.org/2020_Spring_Workshop.htm) for more information.

From the VP - Technology
Jenny LaGesse
This February 18th we are pleased to present Max Peeters and his talk, Clay Types Derived from Logs Using the Petrophysical Stepchild "Photo-electric Effect" and Apparent Matrix Densities. He will be followed by Daniel Krygowski in March with his presentation titled Pattern Recognition in a Digital Age: A Gameboard Approach to Determining Petrophysical Parameters.
Registration and speaker agenda for the 2020 DWLS Spring Workshop: Horizontal Petrophysics: Applications and Interpretation Techniques in Reservoir Characterization will be announced soon. I was thrilled to see the amount of interest in this workshop topic, with so many scientists willing and able to present their work, across a variety of basins and focus areas. It will be held on April 29th in Golden, Colorado, so clear your calendar now for the email announcement to come shortly.
Be Our Valentine: 2020 DWLS Spring Workshop
Roses are red,
Violets are blue,
If horizontal petrophysics is your jam,
Then we’ve got something sweet for you!
Eros and Cupid both agree,
Don’t swipe left on us and run,
April’s workshop is not to be missed,
Getting horizontal with us and log interpretations is too fun!
