Full Waveform Sonic

QL40-FWS

QL40-FWS-S


The ALT QL40-FWS tool is specifically designed for the water, mining and geo-technical industries. Its specification makes it ideal for cased-hole and openhole applications, and for the identification of fractures. Sonic logs are widely used, often in combination with other logs, to provide porosity, permeability and geomechanical properties of rocks.

The new QL40-FWS tool is optimized for such purpose. It implements a high energy source generated by a ceramic-piezoelectric transducer that excites the formations in such a way that waves of different frequencies are developed and propagated.

Real time analysis and processing of the full waveform are performed by the tool to enhance the picking of the different wave propagation modes. The tool can only be operated in a fluid-filled hole. Logging speed depends on tool configuration and acquisition parameters.
