Having written several columns about spudder rigs and the wire lines used on them, I now get to the business end of a spudder: the drill or tool string.
I think the term “string” comes from the fact that it consists of several pieces, each with its own purpose during the actual drilling. Tapered and threaded joints, similar to what one finds on rotary tools, hold the different pieces of the string together. Drilling tools come in all kinds of different shapes and sizes. You’ll find at least many, if not more, tools for driving casing and pulling it back out of the earth, and fishing tools to recover other tools stuck or lost in the hole.
