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.
Measure neutron porosity with azimuthal borehole coverage
Azimuthal Neutron Logging
Our TNP™ thermal-neutron porosity sensor uses multiple He3 detectors at two spacings to provide an accurate, compensated neutron-porosity measurement.
Quantify bulk density with azimuthal borehole coverage
Azimuthal Density Logging
Our AZD® azimuthal density sensor provides accurate, azimuthally focused formation-density and photo-electric (Pe) along with hole-size caliper in both real-time and recorded modes.
Determine neutron porosity and formation density in extreme conditions
Ultra-HPHT Neutron Porosity and Density Logging
The HeatWave® Extreme density service provides real-time measurements in high-pressure, high-temperature (HPHT) environments up to 30,000 psi (206.8 MPa) and 392°F (200°C).
