Placing corrosion test rings in the drill string is one of the more common techniques used to evaluate the corrosiveness of drilling fluids on the drill string and other steel equipment. Removal and examination of these rings, after they have been downhole for some time, can be highly informative as to the corrosiveness of the drilling fluid and the type of corrosion encountered.
