2026 Webinar: Unlocking Subsurface Potential - how 3D modelling drives successful geothermal projects"

As part of the Australian Geothermal Association's webinar series, Samantha Sellars from Seequent discussed the latest in subsurface technology. This includes real-world examples and case studies showing how 3D geological models support geothermal projects—from early exploration and well planning through to long-term resource management. It also features the story behind Seequent’s technology evolution, from roots in medical and film industries to a fully connected suite of geophysical, geological, and engineering tools powering the geothermal asset lifecycle, alongside the role partnerships play in accelerating industry growth.

Presenter:
