Brief description:

At the bottom end of the drill pipe are extra-heavy sections called drill collars, which serve to concentrate the weight on the rotating bit. In order to help maintain a vertical well bore, the drill pipe above the collars is usually kept in tension. This is applicable more on Mud rotary drilling where the equipment is bottom table drive.
