Schlumberger Ngi Tool New! Official

A horizontal well targeting a 10-foot porous dolomite zone. Surrounding the target are dense, non-porous limestone and anhydrite.

The NGI tool provides a direct measurement of gas saturation independent of water resistivity ((R_w)) by exploiting the of reservoir rocks. schlumberger ngi tool

: In more advanced versions like the Rt Scanner Triaxial Induction Service , the tool measures resistivity in three dimensions ( Rvcap R sub v Rhcap R sub h A horizontal well targeting a 10-foot porous dolomite zone

The raw data from the NGI tool is sent to the surface via mud pulse or electromagnetic telemetry. On surface, it is processed through Orbit software * (part of the Delft* platform). : In more advanced versions like the Rt

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.
