Electrical Impedance (Holdup) Measurement: Detect entry/exit from shale caps or non-reservoir layers

Schlumberger NGI Tool (Noise-Ground Impedance)

• Detect entry/exit from shale caps or non-reservoir layers.
• Maintain wellbore within a thin target zone (e.g., 1–3 m thick carbonate or sandstone reservoir).
• Identify "walking" out of zone within one stand of pipe.

Efficiency: 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.

The NGI (Next Generation Imager) is a high-performance borehole imaging tool from SLB (formerly Schlumberger) designed to provide high-definition reservoir characterization. It is primarily used for microresistivity imaging in open-hole environments to visualize geological features like fractures, thin beds, and structural dips. Key Features of the NGI Tool
