COMPENSATED NEUTRON
LOGGING TOOL
- 9075

The Compensated Neutron tool contains a two detector, neutron system which uses a 5.0 Curie, Am241Be source to record neutron porosity of the formation. Additionally, the tool also records short and long neutron counts, natural gamma, temperature and a deep guard resistivity.

Benefits:

Fully downhole digital
Quick automatic setup, unique tool identification
Designed for one-man operation
Can be customized to your specific needs
