Definition The Acoustic Televiewer (ATV) log provides
The Acoustic Televiewer (ATV) log provides a very-high resolution, sonic image of the borehole wall. The tool consists of an ultrasonic transducer coupled with a downhole inclinometer. These devices are used to generate an oriented image of seismic velocity variation and wave amplitude. These images are then examined and highlighted to reveal fractures, bedding planes and orientation of those features. The log is useful for strata and fracture delineation, and can also be used to evaluate compressional-wave velocity, borehole deviation and eccentricity.
