What is well logging?
Usually, when it comes to environmental or geotechnical studies about groundwater, mineral, oil and gas exploitation, it is necessary to well logging for analyzing stratum situation exactly when drilling boreholes. Well logging is performed at various intervals during the drilling of the well and when the total depth is drilled, which could range in depths from 300 m to 8000 m (1000 ft to 25,000 ft) or more. WHA appliance for oil well logging Since well logging always needs entering the earth as deeper as possible to get the characterization of wells, high-performance logging facility is required, and it should be heavy and firmer enough, so as to balance out much more upward resistance and enhance the downward impulse force. In fact, it should just work as counterweight for the whole part. Tungsten heavy alloy (WHA) is an excellent casing material for down-hole logging of oil wells. Casings must be sufficiently heavy to readily sink through materials such as barite mud and strong enou
