ABSTRACT:
A method and means for using nitrogen exhaust gases or gaseous mixtures of combustible products for reduction of oxygen in drilling fluids during the drilling of well bores and which comprises utilizing nitrogen from normally waste exhaust gases or the like, injecting the nitrogen and other gases present into the usual drilling muds for replacing the oxygen contents of the drilling muds with the nitrogen gas, whereby corrosive action of the drilling muds is greatly reduced or substantially eliminated.
