terms:depth_datum
The zero-depth reference for well logging. A location on or above the surface (land or water) at which an elevation can be determined for depth reference. The elevation of this datum will be the reference for all depth measurements made in the well bore. Usually, the top of the kelly bushing is used as depth datum in drilling wells, but could be ground level, derrick floor, or any other specific depth reference.
