Seequent, a business unit of engineering software developer Bentley Systems, said the deal extends its capabilities in groundwater management, as well as for sustainability projects involving exploration, contaminants, and infrastructure resilience.
Aarhus GeoSoftware has developed visualisation solutions for ground-based and airborne electromagnetic (EM), and electrical resistivity tomography (ERT) remote sensing. Aarhus is named after the university in Denmark it was spun out from.
The company's software packages include AGS Workbench, SPIA, Res2DInv, and Res3DInv.
AGS software enables users to create 2D and 3D images of subsurface electrical resistivity, with the outputs of the software used to distinguish and differentiate subsurface materials. These can subsequently be modeled in Seequent's Leapfrog to aid in various subsurface investigations.
AGS uses electric field measurements, collected at ground or airborne levels, to map subsurface distribution of water, mineral deposits, and clays, or other materials. It was originally created to find clean drinking water in Denmark by mapping groundwater. It is now used in construction, and in mining for investigating orebodies and waste rock and tailing processes.
"The acquisition will add new geophysical data processing capabilities to our workflows to help advance subsurface investigation and modelling", said Graham Grant, chief executive officer of Seequent.
"AGS software, coupled with Seequent's advanced geologic modeling and analysis software, creates a key tool in helping understand and manage groundwater and assessing risk in infrastructure".
