Product Details

System Overview

The BCPM1 (Azimuthal Gamma Near-Bit Measurement System) represents Baker Hughes' next-generation core logging-while-drilling (LWD) technology for geosteering applications. Utilizing 360° omnidirectional gamma ray imaging technology, this system acquires real-time formation radioactivity characteristics at only 0.8m behind the bit. Integrated with high-resolution azimuthal measurement capabilities, it provides centimeter-level geological resolution for thin-bed identification (<1m), fault crossing, and sweet spot optimization, significantly improving reservoir contact rates in complex hydrocarbon formations.
