Century Geophysical - Model 9057 -Multi-Parameter Logging Tool for Borehole Data Collection

The Multi-Parameter E-Log Neutron Logging Tool is designed to succeed the historically popular 9055 model. It maintains all the functionalities of its predecessor while introducing additional capabilities such as the 16-inch normal, 64-inch normal, and lateral resistivity measurements. The 9057 model is equipped with a natural gamma circuit that features a low dead time, enabling it to record exceptionally high count rates, particularly beneficial for uranium logging applications. This tool can simultaneously log ten parameters in a single borehole pass, including natural gamma, spontaneous potential, single point resistance, 16-inch and 64-inch normal resistivity, 48-inch lateral resistivity, neutron-neutron interaction, temperature, delta temperature, slant angle (tilt), and azimuth (bearing). Additionally, slant angle, azimuth, and natural gamma functionalities are optional. The tool offers a fully digital downhole setup, quick automatic configuration, unique tool identification, and is designed for single-person operation. The logging speed is up to 9 meters per minute (30 feet per minute), and it requires 60 VDC for operation. It is built to withstand temperatures up to 70°C (158°F) and pressures up to 232 kg/cm2 (3000 PSI).
