[QUOTE="ohiosteve, post: 1498312, member: 17303"] The drilling rig uses a lot of the same components as a vertical rig. Same type of hydraulic drives, same power units same mud cleaning units/shakers and same concept of pumping the drilling mud through the drill pipe and pretty much the same types of reamers. The tricky one is the pilot hole which is 12". The pilot is drilled with a bit that is powered by the drilling mud and the direction of the bit is controlled by gps. This particular bore was about 120' below surface at the deepest. After the final reamer is run through the bore 54" in this case the drill pipe is hooked to the line with a huge swivel and cable. The cable is huge, I'd say 4" diameter. The cable is hooked to the gas pipe with a huge( and I mean huge) clevis, through a pull head that is welded on the end of the pipe. Then the rig pulls the pipe through 30' at a time removing drill pipes one at a time. The gas pipe is supported on about 100 big rollers and by sidebooms with roller slings. In this picture you can see the pull head but the drill pipe is not connected yet.
