2018 Borehole Geophysical Logging Workshops


**Attendees are “highly encouraged” to bring a thumb drive and laptops to follow along and take notes.  Also, they should bring a calculator with simple math functions, the one on their cell phones are fine.

Borehole Geophysical Logging for Water Resources/Water Supply Applications with John Sciacca, P.G. and Bruce Manchon, P.G.

Borehole geophysics is, and will continue to be, a highly effective tool for water resource/water supply applications and is also useful in environmental investigations where, for example, sites must be evaluated to determine the distribution of contaminants. Depending on the objectives of logging program, either qualitative or quantitative interpretation may be utilized. Commonly, geophysical logs are run and are given only a cursory examination before they are filed with the geologic and driller logs. This is a lost opportunity to more carefully analyze and assess aquifer properties. If the investment is made to run a suite of geophysical logs, then an effort should be made to obtain the maximum value from the logs through quantitative interpretation.

Greater technical expertise is necessary for quantitative analysis of borehole geophysical data. This workshop will cover quantitative log analysis techniques to help evaluate porosity, hydraulic conductivity, and transmissivity of the formation.  The workshop builds upon previous introductory workshops and looks at more advanced geophysical logs or in more detail at logs introduced in the previous workshops and their interpretation.  This includes but is not limited to cement bond logs (CBL), Borehole (nuclear) magnetic resonance (BMR/NMR) logs, and imaging logs. In addition, the workshop will further examine interpretation of lithology and correlation from logs, including discussion of representative lithologies in Nevada.  The information from these logs and advanced interpretation can provide fine-scale information on aquifer composition and properties that may be of great value for hydrogeologically complex projects.

This workshop will also provide an advanced framework and criteria for the use of borehole geophysics in the design, construction, and/or rehabilitation/abandonment of resource/water supply wells.  Additionally, the workshop can help support work with aquifer storage and recovery projects and deep injection wells.

The instructors will review a large number of “hands-on” logging project examples as part of this workshop as well as exercises to help enhance learning.  A notebook will be provided with this portion of the workshop, which will document field procedures to be used for the performance of wireline logging, including slides, calibrations and data reporting, and operational constraints. Attendees are encouraged to bring their own geophysical logs, to discuss them with the instructors and workshop attendees.
