WebThe circulating system moves drilling fluid down the drill string, out the bit nozzles, and back to the surface equipment for recirculation. In this module you will learn about the circulating system components, processes for liquid and air/gas drilling fluids, and the critical role that drilling fluid has in the drilling process. Module content: WebJul 1, 2004 · Circulating system All the components of the circulating system – rig pumps, manifolding, check valves, Kelly hose, standpipe and the drillstring – must be able to withstand the injection pressure while mudcap drilling. Double or redundant check valves should be placed between the pump discharge and the standpipe and casing valves.
