A drilling mud fluid is an oil or water-based mix of minerals, salts and polymers formulated to protect the drill and the shaft during oil or gas borehole drilling. Drill cuttings are produced as the rock is broken by the drill bit advancing through the rock or soil; the cuttings are usually carried to the surface by drilling fluid circulating up from the drill bit. The discharge of the oil based cuttings generated with oil based fluids is not permitted in most offshore-drilling areas, thus all such cuttings and waste fluids are processed, and shipped to shore for disposal. Orbinox’s knife gate valves can meet the demands of complex applications.
