STEP-BY-STEP PACKER TESTING
For Hydrogeologic Projects

Packer testing is a technique in which one or more inflatable bladders, or packers, are used to isolate different regions of a borehole for hydraulic testing or water sampling. Although hydraulic packer testing is an "old" technology in the water well industry hydrogeologists often do not appreciate how valuable it can be in understanding and interpreting subsurface hydrostratigraphy, groundwater movement, and aquifer properties. Furthermore, many hydrogeologists do not completely understand the appropriate design, conduct, and interpretation of packer tests.

This webinar will introduce appropriate approaches, methods, and equipment for borehole packer testing applied to hydrogeologic projects. The course will feature step-by-step procedures for conducting tests, and will discuss various methods of test analysis.

TOPICS:

  • Definition and types of packer testing
    • Single packer
    • Multiple packer
    • Permanent versus Temporary
  • Where is packer testing appropriate?
  • Choosing a packer setup
  • Types of hydraulic tests
  • Step-by-step guide to a packer test
    • Test objectives
    • Determining response time
    • Calculating inflation pressure
    • Instrumentation/data collection
    • Typical test responses
  • Methods of analysis
  • Two case studies

WHAT YOU WILL GAIN:

  • Learn where packer testing is, and is not, appropriate
  • Be exposed to modern packer equipment and monitoring instrumentation
  • Receive a step-by-step guide to conducting a test in the field
  • Learn analytical methods for interpreting packer tests
  • Learn to avoid common mistakes


Instructors Bio

Kenneth Bradbury, PhD, PG
( http://www.uwex.edu/wgnhs/staff_krb.htm )

Dr. Kenneth Bradbury is Wisconsin's State Geologist and Director of the Wisconsin Geological and Natural History Survey, UW-Madison Division of Extension. Ken is a hydrogeologist who has worked and published on groundwater issues in Wisconsin since 1982, with a focus on applied problems. His research has included investigations of virus transport in groundwater, groundwater flow in fractured rocks, aquitard hydrogeology, groundwater recharge processes, wellhead protection, regional groundwater simulation, and the hydrogeology of glacial deposits.

He received his B.A. from Ohio Wesleyan University, where he majored in geology, then earned a Master's degree from Indiana University. He received his PhD from the UW-Madison Department of Geology in 1982.

Ken is an affiliate faculty member in the UW-Madison Department of Geoscience and the Nelson Institute at UW-Madison. He is a Fellow in the Geological Society of America and is active in the Association of American State Geologists. Ken has served on the Water Science and Technology Board of the National Academy of Sciences and on committees advising the US Geological Survey.


Dave Hart PhD, PG

Dave Hart is a hydrogeologist/geophysicist with the Wisconsin Geological and Natural History Survey and an associate professor at the University of Wisconsin–Extension.

Dave's applied research includes regional groundwater flow and recharge in southeastern Wisconsin, near-surface geophysics, and measurement of porosities and permeabilities in aquifers and aquitards. Prior to joining the university, he served as a hydrogeologist with Eder Associates. He is an associate editor for Ground Water and past president of the AWRA – Wisconsin Section.
