Robertson Geologging HRAT
The High Resolution Acoustic Televiewer produces an oriented, 360° unwrapped image of the borehole wall from acoustic amplitude and travel-time data, used to map fractures and bedding structure.

About the Robertson Geologging HRAT
By rotating a focused acoustic transducer while logging, the HRAT builds a continuous, depth-registered image of the borehole wall that reveals fracture orientation, dip, and aperture — data that optical imaging alone cannot always provide in turbid or cased holes.
It is a second-generation acoustic televiewer design, refined from Robertson Geo's original 1990s-era instruments for improved image resolution.
