For StandardWITSML v2.0

To digitize a log, the following process must be followed:

  1. Identify the associated well using header information.
  2. Identify the well log tracks, for each track:
  • Identify track left and right edges
  • Identify depth markers in the track, tag depth
  1. For each curve on a well log track, do the following:
  • Identify track left and right scale values
  • Identify curve backup regime
  • Capture curve points either manually or using an automated process
  1. For all captured curve information, use mathematical transformations to convert the captured curve pixel locations to depth/value pairs for each curve.
  2. Resample curve depth value points to industry standard depth step (i.e. 0.5ft, 0.1524m).
  3. Generate flat file of the curves and metadata in industry standard format, such as LAS, ASCII or Excel.
