Borehole Imaging: Acoustic Scanner – Overview
BOREHOLE IMAGING: ACOUSTIC SCANNER APPLICATION: The acoustic scanner is an ultrasonic borehole imaging probe which is commonly run in combination with an optical scanner for detailed, high resolution images of the borehole through 360°. Ideal and commonly used for...
Acoustic scanner (televiewer) versus 3 arm dipmeter
Borehole Imaging: Acoustic Scanner (Televiewers) versus 3 or 4 arm dipmeter. The acoustic scanner and 3 or 4 arm dipmeter probes have been used for coal exploration for a long time. It would be fair to say that the acoustic scanner has superseded the 3 or 4 arm...
Borehole Imaging
Borehole imaging probes are now a common service provided in boreholes drilled for mineral exploration, geotechnical investigations and groundwater programs. The major mineral borehole imaging methods are: Acoustic imaging: requires a fluid filled borehole Optical...
Borehole Imaging – Optical Scanner
Full image coverage of a borehole wall in true colour – the optical scanner probe The optical scanner uses a high resolution digital camera together with magnetometers and accelerometers to provide an orientated true colour image of the borehole wall. Principal...
Borehole Imaging – Acoustic Scanner
Full image coverage of a borehole wall – the acoustic scanner probe. The acoustic scanner, also known as the acoustic televiewer, uses high frequency sound wave echoes together with magnetometers and accelerometers to provide an orientated travel time and amplitude...
