The Near-Gas Imager (NGI) is a wireline logging tool developed by Schlumberger (now part of SLB) designed to address a critical challenge in petrophysics: evaluating low-resistivity, low-contrast (LRLC) pay zones, particularly those associated with gas-bearing reservoirs.
The Schlumberger NGI (Next-Generation Imager) tool—specifically the NGI-X—is a high-definition wireline microresistivity imager designed to provide detailed "borehole imaging" for reservoir characterization. It is often used to visualize formation geology with high precision, especially in complex environments where standard imaging might fail. Key Capabilities and Features
