Abstract:

The successful exploration for groundwater resources in Colorado is a dynamic tension between the what is understood about the hydrogeology prior to drilling and the funding allocated for exploration. Historically, geophysical technologies are often integrated into the exploration workflow after one or more dry holes are realized. Based on this all too common experience, it is logical to adopt the notion that application of geophysical methods should be part of every exploration project. However, financial constraints often temper the enthusiasm into a judicious integration of geophysical technology into the enterprise. The bottom line is that geophysical technologies should be considered for every groundwater exploration and management project but due to financial constraints they may not become an essential component of the endeavor. When they are appropriate, the information derived from the geophysical data will, in every case, lead to better informed decisions.

The results from three (3) recent groundwater geophysics projects will be presented. The first is on the use of electrical resistivity imaging (ERI) method to delineate paleochannel gravel aquifers incised into the Pierre Shale in the prairie east of Fountain, CO. The second is the use of photogeological analysis in combination with ERI to detect and identify fractures in the Mancos Shale on a residential property near Steamboat Springs, CO. The third illustrates how the combination of ERI and seismic reflection were cost effectively used to explore for a deep aquifer in Weld County, CO.

Biography: 

Ronald S. Bell, Senior Geophysicist

Ron has over three (3) decades of experience in the application of geophysical technology to groundwater, mineral, geothermal, and hydrocarbon resource exploration as well as environmental and geotechnical subsurface site characterization. His experience includes the acquisition, processing, visualization and interpretation of terrestrial, borehole, and airborne potential field data including direct current resistivity, induced polarization, time and frequency domain electromagnetic, magnetic, and gravity methods.

In recent times, he has utilized small unmanned aerial systems (sUAS) to perform low altitude, high definition aeromagnetic surveys for oil and gas well head mapping, pipeline delineation, and geological mapping.

Ron holds BS in Applied Physics from Michigan Technological University and has completed geology course work at the University of Colorado at Denver.

In July of 2018, Ron joined Collier Consulting Inc., as a Senior Geophysicist whose responsibilities include new business development. Collier Consulting provides its clients a unique set of skills and experience in the innovative application of geophysical technologies to the exploration for and management of ground water resources as well as subsurface imaging for environmental contamination and geohazard detection, delineation, and monitoring.

Collier Consulting, Inc. is a woman-owned, geoscience and engineering firm headquartered in Stephenville, Texas, with satellite offices in Austin, Houston and Waco, Texas as well as Waukesha, WI and Lakewood, CO. (http://collierconsulting.com/)
