Applications for Conceptual Site Models from Aestus

The Aestus GeoTrax CSM+™ process develops conceptual site models for a variety of applications, including:

  • Delineating the vertical and horizontal extent of light non-aqueous phase liquids (LNAPL), dense non-aqueous phase liquids (DNAPL), and aqueous phase impacts
  • Locating the source of impacts to surface water bodies, such as seeps and sheens
  • Identifying the source and extent of brine spills at oil and gas industry production sites
  • Delineating waste prism and leachate issues associated with landfills
  • Better understanding hydrogeology and preferential pathways, including karst
  • Evaluating bioactivity, including delineating zones of natural or enhanced bioactivity
  • Delineating environmental impacts in sub-aqueous sediments
  • Monitoring substrate injection: where should one inject and where did it go

Other industry applications for conceptual site models from Aestus include, but are not limited to:

  • Siting production water wells, avoiding the costly drilling-blind scenario by scanning first
  • Detecting karst, voids, and caves related to engineering concerns regarding sinkholes and settlement
  • Mapping subsurface geotechnical properties and issues
  • Mapping and imaging subsurface archaeological features
  • Mining operations, such as for locating gold-bearing gravel zones

Applications for 3D and 4D transient subsurface monitoring* available from the Aestus GeoTrax CSM+™ process include, but are not limited to:

  • Monitoring injection sites
  • Determining contaminant excursions beyond a point of compliance or property boundary
  • Mapping subsurface geotechnical properties and issues
  • Locating tunnels related to homeland security concerns
  • Detecting saline intrusion into drinking water wells
  • Check for piping in earthen dams

*3-D and 4-D (i.e., 3-D over Time) transient subsurface monitoring is achieved by installing dedicated electrode cable(s) in the subsurface and monitoring the same set of electrode cables at a set time interval to look for changes in the subsurface that may indicate a problem that needs to be addressed.
