The Acoustic Televiewer takes an oriented "picture" of the
borehole using high-resolution sound waves. This acoustic
picture is displayed in both amplitude and travel time. This
information is used to detect bedding planes, fractures, and
other hole anomalies without the need to have clear fluid filling
the boreholes. The televiewer digitizes 256 measurements
around the borehole at each high-resolution sample interval
(.005 meters/.02 feet). This data is oriented to North and
displayed real-time while logging using the Visual Compu-Log
software. Analysis includes color adjustment, fracture dip and
strike determination, and classification of anomaly. It allows
information to be displayed on the graphical screen, plot, and in
report format. Optionally, the tool can be equipped with a
natural gamma sensor.
