The Compensated Neutron tool uses dual, high-temperature, ruggedized He3 thermal neutron detectors to measure formation porosity through casing and cement.
Analysis of this porosity can help:
- Identify lithology and detect gas
- Identify shale volume
- Provide input for water saturation calculations
When combined with a gamma ray and dual receiver or RadIITM cement bond tool, the data is multiplexed with the Gamma Ray, CCL, and CBL data in a single pass in the well. The tool may also be run with the Gamma Ray/CCL Tool alone.
