QL40-DEN
from Mt Sopris

The QL40-DEN Dynamic Probe is an advanced tool for acquiring high-resolution compensated density measurements across a variety of borehole environments.

Key Features and Functionality:

• Dual Density Data Collection: Captures raw long/short counts per second (cps) and g/cc density data, alongside caliper measurements, for precise compensated dual-density readings.
• High-Precision Detection: Utilizes a Cs137 source, which emits 662 keV gamma particles. Two shielded CsI (Th) scintillator crystals, each coupled to a photomultiplier tube, detect backscattered gamma radiation, sensitive to energy levels >200 keV.
• Electron Density Measurement: The system measures backscattered energy through Compton scattering, enabling accurate determination of electron density rather than bulk density, which is ideal for lithological studies.

Compatibility and Usage:

• Quick Link (QL) Integration: As part of the Quick Link system, the probe can be seamlessly combined with other QL inline subs or used as a standalone tool. It is optimized for 2 to 12-inch boreholes, providing flexibility for diverse applications.
• Stackable Design: Can be deployed as a bottom sub-tool, enabling streamlined operations when paired with other geophysical tools.

Applications:

• Geological and Lithological Analysis: Ideal for assessing subsurface electron densities and identifying variations in rock composition.
• Environmental Studies: Useful for mapping contaminant plumes or soil characterization.
• Mining and Exploration: Provides critical data for evaluating ore densities and deposit quality.

The QL40-DEN probe’s precise measurement capabilities, combined with its robust integration and adaptability, make it an indispensable tool for modern geophysical investigations.
