All of our Raster Well Logs are depth calibrated. We provide depth registrations (depth calibrations) for all raster well logs in the library. We do not just depth register top and bottom of the well log, but utilizing the extensive data recorded by our registration process, we straighten and correct for scale over the full length of registered depth intervals.
