Water Jet Drilling in Sandstone and Granite
Under contract to the U.S. Energy Research and Development Administration the University of Missouri Rolla is developing a high pressure water jet drilling device. This paper describes some of the preliminary work in the laboratory and discusses changes in drilling parameters required for sandstone and granite. A modified drill bit to improve penetration using a combined water jet and roller cone bit is described and preliminary data on the results discussed.
