Depth Track 2: ( \phi_t ) (from density/neutron) overlaid with ( \phi_w ) (from NGI) Track 3: ( S_xo ) from NGI Track 4: Resistivity (deep & shallow)

However, the legacy NGI tool remains in active service in many regions (South America, Middle East mature fields, and North Sea) due to its lower cost and high mechanical reliability. For many operators, the "old" NGI is still the most cost-effective solution for gamma-guided geosteering. Depth Track 2: ( \phi_t ) (from density/neutron)
If you would like to explore specific aspects of this technology further, let me know if I can provide more details on: The used to process the data For many operators, the "old" NGI is still
: It is half the length of a conventional triple-combo tool but logs twice as fast (up to 3,600 ft/h), reducing rig time and costs.
A typical Bottom Hole Assembly (BHA) using the NGI tool might look like this:
