for Challenging Conditions

Designed and priced for the Individual
(at home or in the office)

Despite the popularity and frequency of slug testing, difficulties still exist with design and analysis. Questions about parameters, field screening, data collection, and analysis strategies continue to challenge professionals.

Sometimes these challenges emerge because of the conceptually simple nature of slug testing or lack of meaningful training. Many challenges can be easily overcome by simply learning the key steps that make slug testing more reliable - and easier to do with confidence.

For example, high-permeability formations deserve special attention because of the challenges in collecting reliable data when the test duration is only several to a few tens of seconds. A pneumatically initiated test is one approach for improving the quality of data from tests in high-permeability formations, but it is not the only strategy.

Low-permeability formations pose their own kind of challenge. How can you obtain timely data when the test duration can be extremely long? What strategies exist to obtain reliable data in a reasonable time?

Data analysis can be daunting too. Selecting the most appropriate solution is important for ensuring the validity of the results. Plus, there are efficiencies in the analysis process that most of us do not apply because we never learned about them in school.

Webinar participants will learn the key steps they need to get reliable information from slug tests. Plus they will learn the strategies for successful slug testing in formations with extremely high or low hydraulic conductivity - the bane of hydrogeologists.

Much of the field and theoretical research on slug tests over the last decade has been done by Jim Butler and colleagues. Jim's work is widely recognized by the academic, consulting, and regulatory communities as having led to significant advances in the state of the practice for slug testing.

Jim Butler co-teaches the Midwest Geosciences aquifer testing course (with Glenn Duffield) where he spends an entire course segment on slug testing in formations of high and low hydraulic conductivity. In this webinar, Jim will summarize that material as well as discuss approaches for everything in between those extreme settings.

Whether you want to learn more about slug tests in material of very high or low hydraulic conductivity, this webinar will provide attendees with information that is not available elsewhere on the web.

Instructor Bio

Jim Butler, Ph.D.

Jim Butler is the author of "The Design, Performance, and Analysis of Slug Tests" (Second Edition). He currently is a Senior Scientist and Chief of the Geohydrology Section of the Kansas Geological Survey at the University of Kansas, where he has worked for over 30 years.

His research interests include aquifer testing, assessment of aquifers that support irrigated agriculture, high-resolution subsurface characterization, well responses to natural and anthropogenic stimuli, and the role of phreatophytes in stream-aquifer systems.

Jim holds a B.S. in Geology from the College of William and Mary, and a M.S. and Ph.D. in Applied Hydrogeology from Stanford University. Jim was the 2007 Darcy Distinguished Lecturer of the National Ground Water Association (NGWA), the 2009 Pioneers in Groundwater Award honoree by the American Society of Civil Engineers - Environmental and Water Resources Institute, and, most recently, the 2020 recipient of NGWA's M. King Hubbert Award.

Jim helps advance the environmental and engineering industry through teaching professionals about both slug testing and pumping tests. Jim has taught more than 20 courses with Midwest GeoSciences Group. This webinar is another step toward that advancement and we are grateful to have Jim Butler teach the steps for successful slug testing during this purposeful and applied webinar.
