Seismic data deblending software

Efficient and accurate separation of blended acquisition/simultaneous seismic sources using an inversion-based algorithm

Integrate deblending into your workflow


Iterative FK thresholding finds the most coherent solution

Simple interfaces enable easy integration

  • Iterative FK thresholding inversion algorithm
  • C interface for easy integration into existing software
  • Python, Fortran, C++, and Java wrappers available
  • Suitable for both 2D and 3D surveys
  • Deblend arrivals from multiple multisource groups firing simultaneously
  • Remove interference from nearby surveys (given shot times)
  • Option to specify picks of major arrivals for enhanced separation

200k traces, 3k time samples (2.5 GB)

Deblended in 40 mins on one node

This is a section of a typical 2D survey, with quite good data quality. It has been artifically blended to simulate a high blending situation (an average of 2 seconds between shots). The deblending tool easily removes the blending noise, recovering the unblended data with almost perfect accuracy.
