Gemini: A Fully Operational Broadband Source for Model Building and Imaging

With more and more marine seismic surveys utilizing Full Waveform Inversion for high quality velocity models it will be beneficial to generate additional low frequency energy beyond standard marine air gun arrays. The Gemini source is a novel solution to generating more low frequency energy for FWI, while maintaining sufficiently high frequency energy for typical processing and imaging workflows. This paper will give a brief history of the source and show the field trial data acquired during the Engagement sparse Ocean Bottom Node survey directly comparable to standard air gun arrays.
