QL40-FWS
from Mt Sopris

The QL40-FWS Full Waveform Sonic tool is specifically designed for the water, mining, and geotechnical industries. Its specification makes it ideal for cased-hole and open-hole 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. Under suitable borehole conditions and formations, Compressional (P), Shear (S), Stoneley and Tube wave arrivals can be detected.

The QL40-FWS is not restricted by borehole casing type but does require the borehole to filled with fluid.

Applications

Cased-hole

  • Cement bond logging (CBL)

Open-hole

  • Porosity evaluation
