How do natural gas and oil rigs drill on the horizontal plane?

Question

I get the whole process of shielding the actual bore hole using tubes and concrete as well as the use of mud and air systems to remove debris. But how do the actually get the drill head to turn in the ground and what type of pipe are they using to control/send power down to the head?

Thank you for question! Thank @kinkopoly for answer!
This might make someone laugh, but silly me, I never known they can do it and imagined the result reached in different way – drilling in straight lines and diging holes untill they can reach the bore.
