Azimuthal natural gamma ray
Total gamma ray measurement acquired using a large, shielded detector with high azimuthal sensitivity for delivery of gamma ray image.
Azimuthal ultrasonic caliper
Determined by two 180-opposed ultrasonic transducers located just above the stabilizer to measure borehole diameter, acquiring 16-sector image of the borehole shape while rotating.
Propagation resistivity
Includes borehole-compensated phase shift and attenuation resistivities at two frequencies and five spacings with measurements updated every 2 seconds.
Annular pressure
Measured by a pressure transducer in the tool, allowing effective mud weights to be monitored for borehole stability applications.

Annular temperature
Measured at same point as annular pressure, providing insight into mud condition, temperature experienced by the LWD tool, and operating temperature for environmental correction of formation measurements.
Near-bit inclination
Derived by a single-axis accelerometer located near the base of the tool.
Three-axis shock-and-vibration measurements
Measures axial, lateral, and torsional shock amplitude, shock frequency, and vibrational energy to which the collar is subjected.

Spectroscopy
Spectroscopy data are acquired by a short-spaced gamma-ray detector performing a spectral analysis. Spectroscopy computations are performed downhole, allowing real- time identification of the elemental composition of the formation, formation grain nuclear response, and lithology determination. Volumetric lithology quantification is important for accurate porosity and saturation determination.
Sigma
Sigma, which is primarily sensitive to the presence of chlorine, is used to provide a resistivity-independent formation saturation evaluation, to distinguish formation fluids, and to identify low-resistivity pay zones while drilling.
Neutron-gamma density
Using the pulsed neutron generator (PNG) and a series of detectors, the NeoScope tool determines source-less neutron-gamma density (SNGD) from the gamma rays induced by the interaction of high-energy neutrons with the formation. SNGD can replace the traditional gamma-gamma-density measurement, allowing conventional formation evaluation without the use of a nuclear source.
Thermal-neutron porosity
Using high-energy PNG neutrons with a higher count rate than traditional chemical nuclear sources and the series of NeoScope detectors enables determination of the formation hydrogen index (HI). The high-energy neutrons are slowed down by hydrogen atoms in the formation. The neutron measurements use the count rates from the near and far helium-3 tubes to determine thermal neutron porosity and HI. The HI measurement is less sensitive to environmental conditions than the corresponding thermal neutron porosity measurement.
