Abstract
A work string for completing long lateral well bores is assembled using small diameter drill pipe having a nigh make-up torque for a curved section and lateral bore of a well. A larger diameter drill pipe is used in the vertical section of the well to facilitate pushing the small diameter drill pipe through the long lateral bore.
