EXTON, Pa. — Bentley Programs, Included (Nasdaq: BSY), the infrastructure engineering software program firm, in the present day introduced that its Seequent enterprise unit has acquired Danish firm Aarhus GeoSoftware, a developer of geophysical software program. The acquisition extends Seequent’s options for operational floor water administration, and for sustainability initiatives involving exploration, contaminants, and infrastructure resilience.

Aarhus GeoSoftware, a derivative firm from Aarhus College in Denmark, develops the software program packages AGS Workbench, SPIA, Res2DInv, and Res3DInv for the processing, inversion, and visualization of geophysical information from ground-based and airborne electromagnetic (EM), electrical resistivity tomography (ERT) distant sensing, and different sources. AGS software program permits customers to create 2D and 3D photos of subsurface electrical resistivity. The outputs of the software program can be utilized to differentiate and differentiate subsurface supplies and might subsequently be modeled in Seequent’s Leapfrog to help in numerous subsurface investigations.

The software program makes use of electrical area measurements, collected at floor stage or with airborne sensors, to map the subsurface distribution of sure supplies reminiscent of water, mineral deposits, and clays. Electrical resistivity permits a greater understanding of the distribution of supplies reminiscent of water, mineral deposits, and clays, and when the water incorporates different compounds reminiscent of salt, researchers and {industry} professionals can infer the distribution.

The genesis of AGS software program was to make sure clear consuming water for future generations by mapping groundwater throughout Denmark. It’s now utilized in many alternative areas, together with finding subsurface faults and cavities to mitigate development danger, in mining for investigating orebodies and waste rock and tailing processes, monitoring actions of groundwater and contaminants to assist perceive environmental impacts, modeling dam and tunnel stability, and assessing landslide danger to gauge asset resilience or development plan impacts. Seequent will proceed its custom of collaborating with universities and analysis organizations worldwide by means of ongoing engagement with Aarhus College for the event of AGS geophysical options.

Graham Grant, chief govt officer of Seequent, stated, “The acquisition will add new geophysical information processing capabilities to our workflows to assist advance subsurface investigation and modeling. AGS software program, coupled with Seequent’s superior geologic modeling and evaluation software program, creates a key device in serving to perceive and handle groundwater and assessing danger in infrastructure reminiscent of dams and canals. We’re excited concerning the new prospects this opens up for our collective customers worldwide, bettering life-time digital twins.”

Toke Højbjerg Søltoft, chief govt officer of Aarhus GeoSoftware, stated, “Seequent’s international attain will enable AGS software program to positively influence extra initiatives worldwide. As we proceed to develop options, our customers will profit from our instruments being in Seequent’s ecosystem and workflow. We’re excited to affix Seequent and to work collectively on our shared imaginative and prescient of serving to organizations make extra knowledgeable and sustainable selections by means of a greater understanding of the subsurface.”

Caption: Airborne Electromagnetic (AEM) distant sensing is used to gather intensive volumes of information from an plane. A sensor loop under a helicopter or small airplane transmits an electromagnetic sign to the earth. Primarily based on the subsurface properties, a secondary area is created and measured on the plane. These information are then processed to estimate subsurface electrical properties. The AGS Workbench software program is used for processing, inversion, and visualization of the info collected by AEM and different geophysical strategies.

Airborne Electromagnetic (AEM) distant sensing makes use of electromagnetic induction to gather intensive volumes of information from an plane. It’s a quick and cost-effective manner of subsurface mapping, can cowl massive areas (10s-1000s of km²) in just a few days, requires no new drilling or floor entry, and, utilizing 3D modeling and visualization software program, has a fast turnaround for mapping the subsurface.

The method includes a helicopter or a small airplane towing a sensor loop roughly 100 ft (30 meters) above the bottom. This generates an electromagnetic sign transmitted into the earth primarily based on the subsurface properties, thereby a secondary area is created and measured on the plane. These information are then processed to estimate subsurface electrical properties. Relying on resistivity or conductivity, the returned sign helps geoscientists set up the character of the subsurface.

Caption: Sensing information processed and inverted in AGS Workbench software program can then be mixed in Seequent’s Leapfrog Works to create a 3D mannequin that provides an in depth overview of sources. The above picture is a hydrogeological map of the subsurface of the Principal Aquifer (and components of the Ogallala Aquifer) in Nebraska, United States. Airborne Electromagnetic (AEM) distant sensing was used to seize information from the 4,000-square-mile research space. The colour-coded volumes symbolize eight resistivity classes. Greater resistivity values are represented as yellow to pink (sand and gravel), decrease resistivity values are represented as blue to inexperienced (clay and silt), and brown represents bedrock.
