Acoustic Imager (Televiewer) Tool
High-Resolution Borehole Imaging for Structural Analysis
The Acoustic Imager Tool is a state-of-the-art instrument for producing detailed images of borehole walls. Using the travel time and amplitude of an acoustic signal transmitted and received by a rotating ultrasonic sensor, the tool identifies and characterises fractures, fissures, veins, bedding planes, and lithological changes.
The acoustic data is processed into an unwrapped image log, oriented to Magnetic North, allowing for precise structural interpretation. This capability makes it ideal for analysing borehole stability and subsurface formations, even in challenging conditions such as plastic-cased or unstable boreholes.
