Bentley Systems Announces Seequent’s Acquisition of Aarhus GeoSoftware

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

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 visualization of geophysical data from ground-based and airborne electromagnetic (EM), electrical resistivity tomography (ERT) remote sensing, and other sources. AGS software enables users to create 2D and 3D images of subsurface electrical resistivity. The outputs of the software can be used to distinguish and differentiate subsurface materials and can subsequently be modeled 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 allows a better understanding of the distribution of materials such as water, mineral deposits, and clays, and when the water contains other compounds such as salt, researchers and industry professionals can infer the distribution.
