QL40-FWSM
from Mt Sopris

The QL40-FWS Full Waveform Sonic tool is an advanced and versatile instrument designed to meet the demanding needs of the water, mining, and geotechnical industries. With its robust capabilities, it excels in both cased-hole and open-hole applications, making it an essential tool for a wide range of geological investigations. The tool is particularly valuable for identifying fractures within the borehole, a key factor in assessing the structural integrity and permeability of the surrounding rock formations.

Sonic logging is a widely accepted technique in borehole analysis, and the QL40-FWS tool takes this to the next level by providing detailed insights into porosity, permeability, and geomechanical properties of rocks. By detecting compressional (P) waves, shear (S) waves, Stoneley waves, and tube waves, it offers a comprehensive view of subsurface conditions.

Designed to be highly adaptable, the QL40-FWS is not limited by the type of casing used in the borehole, allowing for greater flexibility in various logging scenarios. However, to achieve optimal performance, it requires the borehole to be filled with fluid, ensuring accurate and reliable measurements. This tool is indispensable for professionals looking to gain in-depth knowledge of rock formation properties and fracture analysis, aiding in more informed decision-making for environmental, geotechnical, and resource management projects.
