Abstract
Apparatus for directional drilling allows an uphole section of drill string to be rotated while maintaining a desired orientation of a bent section of the drill string. In some embodiments, clutches above and below the bent section are selectively operated to rotate the bent section to a desired orientation. Reducing transmissions may reduce the rotation rate of the bent section.
