enables the crew to hoist up lengths of steel pipe (30 foot pieces, traditionally) that will be connected to the drill bit and sent on its way into the earth.

- horizontal drilling (first the drill goes into the earth vertically - later it veers)
- steerable drill bit
- coil tubing (replacing the straight steel pipe)
