Borehole Geophysical Logging for Water Resources/Water Supply Applications

Borehole geophysics is, and will continue to be, a highly effective tool for water resource/water supply applications and is frequently applied in environmental investigations where, for example, sites must be evaluated to determine the distribution of contaminants. This workshop will provide the basic applications of borehole geophysics for designing and completing water production wells, assessing environmental concerns, conducting basin and hydrostratigraphic analysis, and rehabilitating or abandoning water production wells. The workshop will discuss some basic principles of log quality control and the main work products one should receive from a logging program and contractor (logging company).

In addition, this workshop will demonstrate some of important applications of borehole geophysics which include identifying water producing zones in well boreholes; evaluating the thickness and distribution of transmissive units; identifying fractures; evaluating relative water yield and water quality; planning well systems; and planning and evaluating well workovers/rehabilitation and abandonment.

Furthermore, this workshop will provide basic information on the various types of borehole geophysical logs and their function and limitations. Interesting examples of geophysical logs relative to the listed applications and topics covered will be provided.

The instructors will review “hands-on” logging project examples as part of this workshop. Attendees are encouraged to bring their own borehole geophysical logs they have questions about, to discuss them with the instructors and workshop attendees.
