Neutron Porosity and Density Logging

Measure neutron porosity and formation density while drilling

We obtain accurate neutron porosity and formation density measurements at industry-leading logging speeds. In addition to fluid typing and pore pressure evaluation, our neutron and density tools deliver precise petrophysical measurements that help you determine water saturation, lithology, and porosity.

Azimuthal Neutron Logging

Measure neutron porosity with azimuthal borehole coverage

Our TNP thermal-neutron porosity sensor uses multiple He3 detectors at two spacings to provide an accurate, compensated neutron-porosity measurement.
