Century Geophysical - Model 4175 -Dual Neutron Logging Tool for Geological Formations

The Express Stack DualNeutron Tool - 4175 falls under the 4000 series of the Express Stack™ tools. It is designed for logging neutron porosity within geological formations, specifically recording both short and long neutron counts. For effective operation, this tool requires the 4000 Stack Gamma Ray Tool Sub to provide necessary telemetry. Fully digital and tailored for downhole environments, it offers automatic setup and unique tool identification, with customization available according to specific needs. Notable technical specifications include a length of 194.1 cm, temperature sustainability up to 125°C, a diameter of 6.35 cm, and operational pressure up to 350 kg/cm². The tool is equipped with He3 neutron detectors, spaced at 61 cm for far detection and 32.4 cm for near detection. Neutron porosity is measured with an offset of 297.18 cm. With a logging speed of 9 meters per minute, it ensures efficient data recording, making it a reliable option for various subsurface exploration activities.
