QL40 TELEVIEWER OPTIONS
Downhole televiewer tools provide continuous orientated images of the drill hole surface.
Two complementary technologies are available:
Optical televiewer (QL40 OBI 2G) delivers high resolution true color images as an unwrapped orientated image of the borehole wall.
Acoustic televiewer (QL40 ABI 2G) uses a focused ultrasonic beam to scan the drill hole surface providing borehole shape and the strength of the reflected sonic signal.
The Geosensor Televiewer Summary provides further in-depth information.
