Like the gritty, unpolished sound of 80s and 90s rock classics, legacy seismic datasets from those decades – often dismissed for noise and low resolution – are rich with geological insights when paired with modern interpretation tools and AI.
At Dig X Subsurface 2025, Aubin Cosson, Geoscientist at Eliis, will present a compelling case study from the North and Central North Sea, demonstrating how vast archives of public 3D seismic data can be revisited using modern workflows to extract new geological understanding.
Using a Relative Geological Time (RGT) model, the workflow automatically extracts detailed stratigraphic horizons, revealing syn-rift deposits, alluvial fans, volcanic intrusions, sand injectites, and deep-sea sediment channels.
The workflow also mapped out features relevant to drilling risk and safety – such as shallow gas pockets and glacial-related structures – making it applicable beyond oil and gas, into areas like geohazard assessment as well as carbon storage.
One of the most compelling aspects of the study is its speed. What would traditionally take months or even years using manual interpretation can now be accomplished in weeks, thanks to intelligent algorithms and automation.
This efficiency makes revisiting mature basins strategic, enabling exploration teams to reduce costs, identify new prospects, and guide future seismic acquisition.
Join us at Scandic Fornebu on December 03-04 to learn more. The program can be found on the conference website.
During the conference, Eliis will also present a second talk on leveraging AI foundation models and spectral enhancements for interactive seismic interpretation, slashing interpretation time from weeks to days while delivering precise 3D geobody extraction.
