This is the name of a log measured along a well bore (a well-log). The code
SBFH is a unique identifier to recognize this particular log and can be found in any (ASCII) log files provided by the logging company. The official name for this log is
'Smoothed Highside Detector Blade Face'. Usage of this log is not high and encountering it is a rare occasion. This log helps to evaluate the azimuth of a sensor on a logging device, used to determine the orientation of the device.
Simply said, this is a log that describes the horizontal angle measured clockwise from true North. (Also referred to as True Bearing.) Occasionally azimuth will be specified relative to some other reference.This log usually has the unit
'Plane Angle'. This is the angular displacement between two lines extending from the same point, measured in the plane of the two lines.
Data from this log can be used to investigate the azimuth of the sensor. Similar logs are listed below:
