EXTENDED REACH DRILLING METHOD Abstract of the Disclosure This specification discloses a rotary drilling technique for drilling a highly deviated wellbore into the earth's crust wherein a drill string comprised of drill collars and drill pipe is used to advance a drill bit attached to the drill pipe at the lower end of the drill string into the earth and form the wellbore. A first portion of the wellbore is formed to extend into the earth's crust and thereafter a highly deviated second portion of the wellbore is formed by drilling with the drill string arranged to have the drill collars located in the first portion of the wellbore and to apply compressive force on the drill pipe that extends therebelow and thus on the drill bit attached to the lower end thereof to apply the desired weight-on-bit for effective drilling of the second portion of the wellbore.
