Image & Structure Interpretation (ISI)

Back to all Add-ons

The ISI module combines image pre-processing, manual and computer-assisted structure picking tools, classification, correction, and data presentation tools into a powerful interpretation platform.

  • Supports data from acoustic, optical, electrical, deep reading imaging tools, and core/CT scans.
  • Fully integrated workspace covering the entire dip picking workflow.
  • Fully customizable dip classification schemes.
  • Image log edition: depth shift, slice and merge, rotation, and mirror option for easy comparison with core scans.
  • Image log processing: filter, bad trace correction, normalization, brightness & contrast, color classification and color component extraction.
  • Multi-level color palette editor.
  • Picking of planar (e.g., joints, faults, bedding), lineation (e.g. fold axes and mineral lineations), borehole parallel (e.g. breakouts and tensile fractures) and free-hand features.
  • Supports adding partial picks providing feature depth and visible azimuth ranges.
  • Apparent to true azimuth and dip correction.
  • Terzaghi correction.
  • Auto-picking algorithm developed by the Centre of Exploration Targeting at the University of Western Australia.
  • Residual dip analysis.
  • Pick statistics, RQD, and fracture height determination.
  • Interactive dips workspace providing polar, rose, vector and woodcock diagrams.
  • Dedicated data containers to include polar, rose, walk-out, and other diagram types in composite plots.
  • 3D Virtual Reality Borehole Functionality: combines radius and borehole wall information into a virtual borehole.
  • Optional FMS/FMI Wizard converts data blocks into oriented “stripe” images.
  • Core Image Cropper isolates, registers depth, and merges core pictures from core box photographs.
  • Core Shifter workspace iteratively depth shifts core intervals and reorients core scans and picks.
  • Picking of continuous planar features from oriented ultrasonic televiewer image.
  • Collaboration with universities and research institutions leads to innovative processing workflows.
  • Borehole breakout and tensile fracture picking allow for an interpretation of the stress regime.
  • Combining borehole shape and image data in the 3D borehole viewer assists the interpretation.
  • Picking of lineations like a fold axis to derive its depth, trend and plunge.
  • Estimation of the visual mineral content based on color classification.
  • Optical televiewer and cropped core images complement each other in structural interpretation.
  • Reorientation of CT scan image and picks using a borehole image as a reference.
