Large diameter conductor The Conductor Pipe is a large diameter pipe that is set into the ground to provide the initial stable structural foundation for a borehole or oil well.It can also be referred to as a drive pipe because it is often driven into the ground with a pile driver. Conductor pipe is typically set, on petroleum wells, before any drilling operations are performed. It is usually set with special pile-driving or spudder rigs, though the drilling rig is sometimes used to save time and money.
