What Does Washover Pipe Mean?

A washover pipe is a tool to recover a stuck pipe, debris or lost equipment. Attempting to pull out items from a borehole is sometimes called “fishing.” A washover operation uses special equipment depending on the item to be recovered. The terminology is used both in trenchless construction as well as in other industries such as oil drilling.

Trenchlesspedia Explains Washover Pipe

Things don’t always go as planned. In drilling operations, pipes can get stuck and a borehole can contain debris or even lost tools. The aim of a washover operation is to recover these items.

In laymen’s terms, a washover pipe can be described as a fishing rod for drilling operations and may be fitted with any of a variety of special accouterments, which include screw-in subs and overshot tools. Some fittings are designed to recover undamaged pipe. It can also be extended with a drill string until it reaches the stuck pipe or other object.
