Schlumberger - Ngi Tool

As drilling automation and closed-loop geosteering evolve, the philosophy of the NGI—placing sensors as close to the action as possible—will continue to define the future of reservoir navigation. For now, if you see a Schlumberger BHA going into the ground, chances are high that an NGI is leading the way, reading the rocks before anyone else.

The standard LWD resistivity tool (30 ft behind bit) indicates the dolomite is thinning. By the time the signal is processed, the bit has already drilled into the limestone floor. The well is a "geosteering miss," requiring a costly cement sidetrack. schlumberger ngi tool

Designed for high-pressure/high-temperature (HPHT) environments, the tool can operate at temperatures up to 300°F (149°C) and pressures reaching 20,000 psi. Key Features and Performance Mnemonics, Tools, NGI-X By the time the signal is processed, the
