Compensated Neutron Tool
The Compensated Neutron Tool (CNT) measures the hydrogen index of formations. Measurements are converted to porosity values, in combination with density tool measurements provide an indication of lithology and gas in zones of interest.
The CNT contains a side loaded 15-20 Cu AmBe neutron source that bombards the formation with fast neutrons. These neutrons are slowed and then captured, primarily by hydrogen atoms in the formation. The slowed neutrons deflected back to the tool are counted by dual ruggedized, high temperature proportional He3 detectors.
Data transmission to surface is accomplished with the use of a ruggedized multiple line driver or optional digital telemetry which both encodes the data for transmission and multiplexes signals from other tools within the tool stack.
