The Schlumberger NGI (Near-bit Gamma Imaging) tool is a logging-while-drilling (LWD) device positioned directly behind the drill bit. Its primary function is to provide real-time, high-resolution gamma ray measurements with directional sensitivity at the bit . Unlike conventional gamma ray sensors located 10–30 meters behind the bit, the NGI tool delivers near-instantaneous lithology detection, enabling precise geosteering, early formation evaluation, and optimized well placement—especially in thin-bedded or heterogeneous reservoirs. schlumberger ngi tool
