Summary

EPO published patent application EP4392812A1 for Schlumberger's AI-based seismic data deblending system designed for CO2 monitoring applications. The invention utilizes neural networks (G06N 3/02) to separate blended seismic signals in simultaneous shooting time-lapse surveys, enabling more efficient subsurface monitoring for carbon capture and storage projects.

What changed

EPO published patent application EP4392812A1 for a machine learning-based system to deblend simultaneous shooting time-lapse seismic data used in CO2 monitoring. The technology, classified under G06N 3/02 (neural networks), G01V 1/32, and G01V 1/28, was developed by inventors Wenyi Hu, Aria Abubakar, Haibin Di, and Zhun Li for applicants Schlumberger and GeoQuest Systems B.V.

This is a patent publication notice, not a regulatory rule. It grants no compliance obligations or deadlines. Companies interested in carbon capture seismic monitoring should review the patent claims to determine if licensing is needed before implementing similar technology.
