π Pleased to share our progress in history matching with seismic data assimilation π

Weβve been investigating how AI can support the Ensemble Smoother with Multiple Data Assimilation (ES-MDA) to improve history matching and reservoir model updates. By using AI to reduce seismic data volume, weβve been able to save time while achieving results comparable to the standard ES-MDA approach.
π Key Achievements:
β
Reduced seismic data using pre-trained AI for 2D and 3D models π€
β
Estimated time reduction between 50% and 90% β²οΈ
β
ES-MDA + AI (2D and 3D) performs similarly to standard ES-MDA
β
Both methods include localization techniques for reliable integration
The attached images compare the reference Porosity and Seismic observable data (delta P-impedance) from the PUNQ Benchmark reservoir with results from standard ES-MDA, ES-MDA + AI (2D), and ES-MDA + AI (3D).
This work suggest a practical way to speed up history matching and 4D seismic applications while maintaining reliability.
