New Drilling Technique (Nitrogen Cap Drilling, NCD).

Recently has been implanted a new drilling technique very different, in which the drilling fluid pumped through the drill pipe doesn’t return to the surface, it is lost to the formation. In the annulus (Drill pipe- Casing, Drill Pipe – Formation) a very viscous fluid is placed (it doesn’t circulate) and an appropriated amount of nitrogen is pumped above this fluid to keep the annular hydrostatic pressure balanced with the formation pressure.
