compensated neutron log. Radioactive neutron source bombards the formation with high energy neutrons, which are slowed and captured by atoms of the formation. The low energy neutrons are reflected back to the tool and counted. The amount of neutrons retur

n: a measure and record of limestone porosity. The log is produced using one source and two detectors instead of just one detector, as an uncompensated neutron log does. A compensated neutron log is less influenced by borehole effects than an uncompensated neutron log. See borehole effect.

n: Schlumberger/Anadrill LWD tool that bombards the formation with fast neutron. Detectors measure the slowed neutrons that are bounced back by Hydrogen atoms. Used to deduce porosity, lithology, clay analysis, and gas detection.
