Process of Drilling - All Star Training
allstarce.comDrilling fluid is pumped down through the hollow drill pipe using a centrifugal pump (mud pump) to a drill bit. The flud flows upward in the annular space between the drill pipe and the borehole to the surface where it is channeled into a settling pit and most of the cuttings drop out. Fluid from the settling pit overflows into a second pit ...
