Brad -- A well will be drilled down to reservoir depth gradually building angle to roughly 80-90 degrees with a bent housing mud motor, usually around 1 1/2 degree of bend,a mud motor is a tool with a stator inside that works similar to a hydraulic motor, when fluid is pumped through the mud motor at high pressure and volume the stator turns the bit. After reaching the horozontal point normally a more advanced mud motor that can be surface contolled or steered by a computer is used. In 99% of the wells the same drill pipe is used that would be used in a straight hole, the pipe its self is very limber in long sections and can be pushed with no problem. Basically, the drill string components that are normally used right above the bit for drilling weight when drilling a straight hole are moved up in the vertical section to push the lower limber section when drilling horozontal.
