9057 – Neutron Tool

The Multi-Parameter E-Log, Neutron logging tool was developed to replace the 9055 which was historically Century’s most popular tool. The tool duplicates all parameters on the 9055 while adding the 16” normal, 64” normal and lateral resistivities. The 9057 natural gamma circuit features a low dead time and the ability to measure very high count rates making it a favorite for uranium logging. The tool records ten different parameters simultaneously in one pass of the borehole. The ten parameters are natural gamma, spontaneous potential, single point resistance, 16” normal resistivity, 64” normal resistivity, 48”. lateral resistivity, neutron-neutron, temperature, delta temperature, slant angle (tilt) and azimuth (bearing).
