Strengthens Seequent’s subsurface software portfolio, energy and geophysics capabilities, and expands team of specialists

EXTON, Pa.--(BUSINESS WIRE)-- Bentley Systems, Incorporated (Nasdaq: BSY), the infrastructure engineering software company, today announced that Seequent, The Bentley Subsurface Company, has acquired seismic interpretation software company Eliis. The acquisition will enrich Seequent’s capabilities in geophysics with seismic data interpretation and further advance subsurface understanding to help solve complex global challenges. Eliis’ global team of more than 100 geoscientists, technical specialists, and researchers will join Seequent.

Founded in 2007 and with headquarters in Montpellier, France, Eliis develops advanced seismic interpretation software that helps geoscientists process and analyze seismic imaging data to build detailed models of the subsurface. Seismic methods provide the highest-resolution geophysical picture of the subsurface at depth.

Eliis’ software includes seismic interpretation platform PaleoScan, with its patented Relative Geological Time technology and AI-assisted interpretation capabilities, that is used by hundreds of energy companies, and groundbreaking industry co-innovation project PaleoModel to enable downstream reservoir simulation. Eliis’ seismic interpretation capabilities complement Seequent’s subsurface portfolio including its implicit modeling tool Leapfrog.

Graham Grant, CEO, Seequent, said, “I am delighted to welcome Eliis to Seequent. Global challenges—notably energy security, the energy transition, and the demand for critical resources—are increasing the need for deeper subsurface insight. Lower cost seismic data acquisition and AI are expanding the adoption of seismic methods beyond oil and gas. We see huge opportunity in energy, mining, as well as groundwater management, the recovery of minerals from brines, and carbon storage. For example, seismic interpretation helps mining companies reduce geological uncertainty and discover deeper mineral deposits compared to traditional methods. Eliis will strengthen Seequent’s ability to help our users understand the underground, reduce uncertainty and risk, and make better, faster, and more confident decisions.”

Benoît Matha, CEO, Eliis, said, “Seequent’s acquisition of Eliis provides us with a secure, long-term home in a company that deeply understands and values our expertise and software. The combination of Eliis’ seismic expertise with complementary geoscience and reservoir technologies will accelerate our ambition to become a leading subsurface technology platform beyond the energy industry —extending our reach across the subsurface workflow and unlocking new growth opportunities. We are excited to join Seequent and by the opportunities ahead.”

Dechert LLP and Simmons & Simmons LLP acted as legal advisors to Bentley and Seequent in the transaction.

Key Terms

seismic interpretation technical

Seismic interpretation is the process of turning underground sound‑wave data into maps and models of subsurface rock layers and structures, similar to how an ultrasound creates an image of the body. For investors, it matters because these maps are used to judge whether oil, gas or mineral deposits are likely present, how big they might be, and how risky or expensive it will be to drill or mine, directly affecting a project's value and financing prospects.

seismic imaging data technical

Geophysical measurements collected and processed to produce visual representations of the Earth’s subsurface. Seismic imaging data comes from controlled energy sources (or passive earthquakes) and arrays of receivers that record returning seismic waves; after processing those recordings into 2D lines, 3D volumes or time‑lapse (4D) datasets, interpreters use the resulting images to map rock layers, faults and potential fluid-bearing reservoirs. It is an indirect, interpretive product whose resolution and accuracy depend on survey design, processing methods and geologic complexity.

reservoir simulation technical

A reservoir simulation is a computer model that predicts how fluids (oil, gas and water) move through the porous rock of an underground reservoir over time. It combines a 3D representation of the reservoir’s geology with measured rock and fluid properties, well locations and operating conditions, then numerically solves the physical conservation equations (mass and, when needed, energy) on a discretized grid to forecast pressure, saturation and production. The accuracy of a simulation depends on the quality of input data and model assumptions; different approaches (black‑oil, compositional, thermal) are used depending on the fluids and processes being modeled, and simulations are commonly calibrated to historical production in a process called history matching.
