Acoustic Televiewer


The HRAT provides a continuous high-resolution oriented ultrasound image of the borehole wall. Features such as fractures reduce the reflected amplitude and appear as dark sinusoidal traces on the log. Directional information is also recorded and used to orient the images in real time. Natural Gamma measurement apparatus are added for correlation other data on the probe.

Borehole imaging applications are executed with this probe is manufactured by Robertson GEOLOGGING.
