Shenkai AziExpress geosteering combination instrument (azimuth resistivity) is a precise geosteering tool and a major national scientific instrument research result undertaken by Shenkai Company, with completely independent intellectual property rights. It integrates measurement parameters such as azimuth resistivity, azimuth gamma, compensation resistivity, annular pressure, and wellbore temperature in one drill, with high integration

Azimuth resistivity is mainly used in complex formations and thin reservoir construction. It provides real-time edge positioning, reservoir tracking, oil-water interface detection and other functions while drilling, realizing precise geosteering and wellbore trajectory optimization. It also helps in water saturation analysis, wellbore cleaning, and well kick and leakage prediction to ensure that the drill tool passes through high-quality parts in the reservoir, improve the drilling rate of high-quality reservoirs, single well production, and improve drilling safety
