With pSTAx software, geoscientists perform post-stack processing flows directly from the desktop, no external reprocessing necessary. pSTAx can be used as a standalone application supporting SEG-Y formatted seismic data, or in conjunction with GVERSE Geophysics, as geoscientists accomplish input and output using bricked formats.

Standard, post-stack processing functions, such as amplitude scaling, correlations, convolution, filtering, and phase rotation build an ideal desktop environment for the quick and easy evaluation of the effects of new processing flows.
SCAN software is an optional extension of the seismic processing module pSTAx. SCAN calculates Event Similarity Prediction (ESP) similarity volumes as well as Structure Cubes from the input data.

With SCAN, the geoscientist readily identifies subtle discontinuities in the seismic data potentially related to geological features. This tool provides a cost-effective alternative to project outsourcing.

  • Easy identification of linear features such as faults, fractures, reefs and channels
  • Interpretation of subtle discontinuities in seismic data..
  • Identification of subtle stratigraphic changes such as channel thickening.
