drillpipe

Wellbore drilling tube

Drillpipe is the steel tubing that connects a drilling rig to the drill bit deep underground.

Sections of drillpipe are screwed together as the well goes deeper, transmitting rotation and drilling fluid to the bit while allowing cuttings to flow back up.

They added another stand of drillpipe as they approached the target depth.
