The SureLog-AZG azimuthal gamma ray LWD sensor sub from APS Technology enables accurate geosteering by adding imaging capabilities to existing APS measurements. The sensor was designed for low power consumption and is backward compatible with APS’s MWD/LWD systems. It can be programmed to acquire gamma ray data up to 24 azimuthally sectored binds around the borehole, as well as provide a total gamma ray measurement. The sensor employs three shielded gamma ray detectors with photomultiplier tubes and a directional package mounted in a collar-based system that provides protection against high levels of shock and vibration. 860/613-4450; www.aps-tech.com.
