What is Oil Well Logging?

Usually, when it comes to environmental or geotechnical studies about groundwater, mineral, oil and gas exploitation, it is necessary to analyze strata properly before 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 Application for Oil Well Logging

Since well logging requires penetrating the earth as deep as possible to get the characterization of wells, high-performance logging tools are required, and counterweights should be heavy and firm enough, so as to balance out much more upward resistance and enhance the downward impulse force.

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 enough to withstand the hydrostatic pressure of this harsh environment. Most designs are highly machined for sensor and window positioning. Mechanical properties are very significant to the survivability of these rather large components.

Owning to its high density (18.5g/cm3 max, hardness as 36 HRC max), its high wear-resistance, high impact resistance and excellent durability, tungsten heavy alloy (WHA) is the optimal material for down-hole logging of underground water, oil and gas, etc.

We also offer Tungsten heavy alloy products related to the petroleum industry. We can offer various tungsten heavy alloy products as counterweights for logging tools, also we would like to design the drawing or manufacture of concrete products according to customer’s special requirements.
