AGDeblend

AGDeblend contains tools to deblend seismic data (separate overlapping shots) and synthetically blend or adjust pseudo-deblended data.

It is quick and easy to setup for simple cases, but provides flexibility to handle real-life datasets.

Features

• Written in C, with wrappers provided for Python, Julia, and Fortran
• Uses basis pursuit (L1 norm minimising inversion) in the Fourier domain
• Parallel processing using MPI (optional) and OpenMP (also optional)
• Works with any data arrangement and number of dimensions ((SourceX, SourceY), (SourceX, ChannelX, ChannelY), (CMP, Offset), etc.)
• Works with any library that implements the FFTW3 interface (such as FFTW3 and Intel MKL)
• Support for:
  • Bad and missing traces (and thus irregular data volume shapes)
  • Source wavelet convolution (useful for Vibroseis data)
  • Disjoint source volumes (sources operating in separate areas or interference from another survey)
  • Disjoint recordings (there may be gaps in the continuous records)
