Data quality control process

Ensure all required data is present; check for any problems noted during logging.

  • QC of tool orientation and behavior during logging.
  • Comparison of borehole trajectory as calculated by the tool and by independent geographical survey.
  • Correction of images for tool sticks and tool pulls.
  • Depth matching of image to open-hole reference log suite where applicable.
  • Image polarity.
  • Hole condition.
  • Verification against any overlapping image runs.
