The 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. Employs advanced impedance measurements (e
Formally part of Schlumberger’s PeriScope Edge family, the NGI tool is the hardware enabler for "look-ahead" and "look-around" capabilities. It utilizes a multi-spacing, multi-frequency array design that allows petrophysicists to see bed boundaries up to 18 feet away from the wellbore—long before the drill bit actually crosses them. Employs advanced impedance measurements (e.g.
