Following you find a short description of the available modules:

module 2D data-analysis for GPR, reflection seismics, refraction seismics, borehole-borehole data

  • Easy import of data of many different formats (e.g. SEGY, SEG2, most of the GPR- and seismic systems (for example: GSSI, RAMAC, PULSE-EKKO, ABEM, OYO, Summit and so on), integration of other non-standard formats
  • Many different processing possibilities - interactive processing of single files or by generating a batch-file, one- and multi-channel filters, editing, static correction, deconvolution, migration and much more. All processing steps are documented.
  • Conversion of single sections and of a profile sequence (automatic assembling and storing of the sections under one single datafile or automatic generation of datafiles for parallel and inline- sections)
  • Velocity analysis of zero offset or shot data using an interactive hyperbola or line adaptation or an intercepttime method
  • Picking of arrivals - manual, automatic or semi-automatic, ASCII-conversion of the picks
  • Single-shot CMP processing (sorting, display, processing, NMO-analysis, stacking)
  • Interactive analysis of CMP- or shot-data using a semblance analysis or an interactive adaptation method calculating either the reflection hyperbolas (reflection seismics) or the complete traveltime branch including diving waves (refraction seismics).

module 3D data-interpretation for GPR and reflection seismics

  • Display of x-,y- or z-slices. The slices are either displayed in manually scalable windows or by moving through the 3D-dataset using a track bar
  • 3D-cube display of the individual slices or of the full 3D-data using shading algorithms
  • Picking of arrivals and contour display of the picked reflectors

module modelling with wavefield simulation and traveltime inversion for refraction seismics, borehole-borehole data, GPR and reflection seismics  including

  • refraction traveltime analysis for refraction seismics
    • Interpretation of refraction seismic first arrivals. The module includes various sorting and combining possibilities for the picked traveltimes.
    • These combined traveltimes are the bases for a FD based wavefront-inversion.
    • An interactive 1D-velocity analysis tool allows the adaptation of the complete traveltime branch including diving waves.
    • Different raytracing methods are available for the evaluation of synthetic traveltimes.
    • A refraction tomography based on SIRT is incorporated for the inversion of the traveltimes.
  • forward modelling for simulating the electromagnetic and seismic wave propagation in a 2-dimensional medium using a Finite Difference scheme
  • A tomographic approach based on SIRT is incorporated for the inversion of the picked traveltimes (refraction and transmission). Straight and curved rays are supported
