Basic Seismic Data Processing Package

System Overview
Basic seismic data processing package mainly includes conventional processing functional modules such as project creation and management, geometry definition and QC, elevation and field statics correction, noise attenuation, amplitude recovery, deconvolution, residual reflection statics correction, velocity analysis and stack, etc.

System Function

  • Multi-attribute vector denoising: coherent noises can be predicted and extracted by analyzing various features and changes of coherent characterization, and then subtracted from original data.
  • MCCNA multiples removal by wavefield separation: applicable to the removal of full-way/interbed multiples caused by offshore streamer feather or rugged sea bottom.
  • Broadband constraint wavelet deconvolution: of high resolution, stable operator, high SNR and can get a better deconvolution result for low SNR data.
  • Ray tracing NMO: reflection events can be flattened from near offset to far offset and this can effectively solve the NMO problem when the cable length is very long.
  • Horizon-controlled velocity analysis: velocity interpolation/extrapolation can be done under the control of reflection horizons to get more geologically reasonable velocity field for strata with weak reflections or nearly no reflections.
