Expo workshop spotlight — Overcoming Grouting Challenges: How the Professionals Do It

Learn valuable information from leading industry experts at this year’s Expo workshop and panels.

Find out more in today’s sneak peek video.

Stewart Krause invites you to attend a workshop being offered that will share insight on the limitations of engineered grouts, pour or pump decisions, multiple completions, annular size, and problem solving for completion and abandonment.  Other presenters include Jim Piasecki  of Drilling Products, CETCO and Jeff Blinn of Baroid Industrial Drilling Products, Halliburton. This panel will be moderated by Roger E. Renner, MGWC of E.H. Renner & Sons Inc., Elk River, MN. You won’t want to miss this informative panel!

Flashback Friday video — Using Sand Tank Models to Teach About Groundwater

This year’s Expo is right around the corner! We can’t wait to bring you the best educational offerings from industry experts.

In today’s Flashback Friday video, we’re taking a look back at a 2012 Expo presentation “Using Sand Tank Models to Teach About Groundwater” by NGWA member W. Richard Laton, Ph.D., PG, CHG, CPG, of California State University, Fullerton. Whether you are participating in a career day or sharing with a service group, sand tank models illustrating groundwater movement can be effective tools. They can literally set the stage for your presentation or become the focal point. Learn how you can use these tools in groundwater presentations.

Don’t miss the 2014 Darcy lecture farewell presentation

Wednesday, December 10, 1:30-3 p.m.

Don’t miss the NGWREF 2014 Darcy Lecture Series in Groundwater Science farewell presentation from Dorthe Wildenschild, Ph.D. at this year’s Expo.

What Happens in the Pore, No Longer Stays in the Pore: Opportunities and Limitations for Porous Media Characterization and Process Quantification Using X-ray Tomography


Dorthe Wildenschild, Ph.D.

During this presentation, you will receive an overview of the current state of imaging of porous media systems — and processes taking place within them — using x-ray tomography, a technique that allows for three-dimensional observation and measurement of variables internal to an otherwise opaque object. Gain insight on how x-ray tomography has advanced to the point where it is possible to probe porous media in great detail, allowing for fully quantitative analyses of processes and mechanisms at the pore scale. Applications of the technique for the remediation of non-aqueous phase liquid in groundwater, the fundamentals of multiphase flow, and the geologic sequestration of carbon dioxide will be presented.Also discussed will be technique limitations, as well as new potential advances that will allow for exciting new research in coming years.

Dorthe Wildenschild, Ph.D., is an associate professor in the School of Chemical, Biological and Environmental Engineering at Oregon State University.
