Verso: Model of a typical oil derrick - a drilling bit is attached to the bottom of a long steel pipe and rotated at the derrick floor. The drill pipe is hollow to permit a stream of mud to be piped down, to keep the bit cool, and to wash away the rock debris. As each 30 feet of hole is drilled, another section of drill pipe is added. The drill pipe is often thousands of feet in length. Hall of Oil Geology Series Code: 87031. Publisher: Dexter Press, Inc.
