Bentley’s Seequent gets geophysical with Aarhus GeoSoftware buy

Bentley Systems’ newly acquired business unit, Seequent, has added Danish company Aarhus GeoSoftware, a developer of geophysical software, to its portfolio.

The acquisition extends Seequent’s solutions for operational ground water management, and for sustainability projects involving exploration, contaminants, and infrastructure resilience, Bentley said.

Aarhus GeoSoftware, a spinoff company from Aarhus University in Denmark, develops the software packages AGS Workbench, SPIA, Res2DInv, and Res3DInv for the processing, inversion, and visualisation of geophysical data from ground-based and airborne electromagnetic, electrical resistivity tomography remote sensing, and other sources. AGS software enables users to create 2D and 3D images of subsurface electrical resistivity, according to Bentley, with the outputs used to distinguish and differentiate subsurface materials. They can subsequently be modelled in Seequent’s Leapfrog to aid in various subsurface investigations.

The software uses electric field measurements, collected at ground level or with airborne sensors, to map the subsurface distribution of certain materials such as water, mineral deposits and clays.

Electrical resistivity, Bentley says, allows a better understanding of the distribution of these materials and, when the water contains other compounds such as salt, researchers and industry professionals can infer the distribution.

The genesis of AGS software was to ensure clean drinking water for future generations by mapping groundwater across Denmark. It is now used in many different areas, including investigating orebodies and waste rock and tailing processes in mining.

Seequent says it will continue its tradition of collaborating with universities and research organisations worldwide through ongoing engagement with Aarhus University for the development of AGS geophysical solutions.

Graham Grant, Chief Executive Officer of Seequent, said, “The acquisition will add new geophysical data processing capabilities to our workflows to help advance subsurface investigation and modelling. AGS software, coupled with Seequent’s advanced geologic modelling and analysis software, creates a key tool in helping understand and manage groundwater and assessing risk in infrastructure such as dams and canals. We’re excited about the new possibilities this opens up for our collective users worldwide, improving life-time digital twins.”

Toke Højbjerg Søltoft, Chief Executive Officer of Aarhus GeoSoftware, said: “Seequent’s global reach will allow AGS software to positively impact more projects worldwide. As we continue to develop solutions, our users will benefit from our tools being in Seequent’s ecosystem and workflow. We’re excited to join Seequent and to work together on our shared vision of helping organisations make more informed and sustainable decisions through a better understanding of the subsurface.”
