Geophysics

Filling the gaps between boreholes

BGC’s geophysics team uses non-invasive geophysical methods to help characterize subsurface conditions, helping to provide critical information on below-ground conditions that may not be attainable through drilling or excavation. Our decades of combined experience, in-house geophysical equipment, and customized tools for sophisticated data processing, interpretation, presentation, and reporting allow BGC to provide customized services and solutions. Our geophysics team delivers high-quality solutions that allow our clients to make sound engineering decisions and, in turn, build challenging and ambitious projects.

BGC’s application of geophysics to the geological and engineering practice is fundamental to our work. As part of BGC’s in-house geophysics capabilities, we offer expert services in near-surface geophysical assessments for a broad variety of applications. Our team has extensive experience planning and executing customized geophysical programs in a wide variety of site conditions all over the world to meet our client’s site-specific needs.

Geophysical surveys are an efficient, cost-effective, and non-intrusive method of collecting high-density subsurface data. They allow for the optimization of more costly programs such as drilling or excavation by providing planners with geological information as well as potential targets for further investigation (e.g., mapping of contaminate plumes). 

Our geophysical experts can also combine the geophysical results with co-located subsurface information (e.g., lithology logs, chemistry, geological models), creating an integrated 3D site model, which can be used to gain a comprehensive understanding of site conditions and help identify data gaps. Alternatively, our data can be provided in a variety of data formats so it can be easily utilized by drafting and GIS teams. 

We pride ourselves on quality and developing innovative approaches, which means we are continually updating technology and methods for field data acquisition, data processing, and reporting deliverables.

Some applications for these technologies include the following:
  • Site assessments (contaminated sites and liability management)
  • Mining
  • Water exploration and management
  • Resource exploration
  • Engineering geophysics
  • Historical and archeological studies
Our geophysical capabilities include the following techniques:
  • Electrical Resistivity Tomography (ERT) and 1-D Resistivity Soundings 
  • Electromagnetics (EM) techniques, including terrain conductivity, metal detection and VLF 
  • Towed- Transient Electromagnetic System (t-TEM)
  • Magnetics (ground or UAV based) 
  • Ground Penetrating Radar (GPR) 
  • Seismic Refraction Tomography (SRT) 
  • Seismic Reflection 
  • Multichannel Analysis of Surface Waves (MASW) 
  • A comprehensive suite of downhole logging tools for geological, geotechnical and groundwater characterization 
  • UAV Photogrammetry, Multispectral and Thermal Imaging 
  • Nuclear Magnetic Resonance (NMR) surface and downhole methods 
  • Distributed Temperature Sensing (DTS)
