There are two main ways to approach the separation of simultaneous source data
Acquisition with blended sources is a way to efficiently acquire high-density seismic data
The overlapping sources must be separated (deblended) before the data can be processed further. TGS has a range of deblending algorithms well suited to different types of acquisition, such as marine streamer and ocean bottom node data, as well as different geological settings:
- Multidomain Coherency Filtering (MCF) uses the unique High-Resolution Moveout Transform (HMT) to separate continuously recorded overlapping shots records.
- Enhanced Adaptive Subtraction (EAS) performs
sourceseparation using state of the art denoise and adaptive subtraction techniques.
- Pure and hybrid Inversion based deblending schemes in the sparse Tau-P and 3D FK domains efficiently separate any number of overlapping sources.
