To pump a quantity of heavy mud into the drill pipe. Before hoisting drill pipe, it is desirable (if possible) to pump into its top section a quantity of heavy mud, or a slug, that causes the level of the fluid in the pipe to fall; thus, when a stand of pipe is unscrewed, the drilling fluid has been emptied out of it so that the crew members and the rig floor are not contaminated with the fluid.  2, fiche 1, Anglais, - slug%20the%20pipe
