QL43-ABI
Acoustic Televiewer
High temperature acoustic borehole imager
Description
The QL43-ABI is the most compact high-resolution ultrasonic imaging tool available in the wireline logging industry. Based on more than 20 years of experience and market leadership with ultrasound technology, the QL43-ABI consists of a state-of-the-art electronics and sensors designed to meet the oil & gas industry standards. The electronic architecture uses a super fast digital signal processor performing complex data processing operations in real time on each individual ultrasonic wave train. Its wide dynamic range of signal detection and its easy field operation offer a large variety of logging applications.
