• Graphical application for field and well structural data evaluation and processing.
  • Free and open source software.
  • Easy to use Graphical User Interface, data processing takes just a few clicks.
  • Separate processing and plot for different wells, localities, data types, data groups and formation.
  • Displays well structural data on well plots, and field data on stereonets and rose diagrams.
  • Tectonic transport direction display and mean transport direction calculation.
  • Displaying multiple data groups on the same stereonet.
  • Bedding correction for tilting test available.
  • Trajectory correction for borehole data is supported.
  • K-means clustering to identify data groups in an inhomogeneous data set.
  • Eight different inversion methodologies and fracture geometry statistics.
  • Data input in Excel or any other spreadsheet application of your choice (such as OpenOffice or Gnumeric).
  • Output in Adobe Portable Document Format (PDF) for individual files, and a single merged file.
  • Optionally, Encapsulated Post Script (EPS) is also available as output format, useful for publications.
  • Both output options are possible in grayscale as well (ideal for gray scale publications).
  • Rich documentation.




  • Average calculation for structural trends: average feature dip direction / dip angle calculation along well bore using fix data number bin or fix interval bins.
  • Standard deviation and relative error calculation for the processed bins.
  • Feature frequency calculation.
  • Derivate curve to show out-of-trend zones: investigation of out-of-trend zones using first derivate curve of the average and frequency curves.
  • Peak detection for deformation zones: changes on average, frequency and derivate curve can indicate a zone of deformation.
  • Faults probability: abrupt change in feature geometry and/or frequency can indicate a zone of deformation.
  • Using changes both of average and derivate curve, and reliability of those changes, probability of fault zones can be predicted.




  • Angelier or Hoeppner plot, Schmidt or Wulff net, upper or lower hemisphere projections are possible.
  • Symmetric / asymmetric (bidirectional / unidirectional) rose diagrams with different bin size are available to plot dip direction or strike of data.
  • Contouring data set using four different possible inputs.
  • Slickenside data correction on two different ways.
  • Full automatic data processing option.
