Overview: Ammonia-derived chemicals including amines, amides, polyamides, imines, nitriles and amino acids are used in many water-based drilling fluid components. Addressed in this paper are those derivatives, which contribute to clay and shale stability. Ammonium chloride was tested more than 30 years ago as a shale inhibitor. Diammonium phosphate has been used for more than 20 years. Organo-amines were more recently introduced. Relatively simple organic amines were first added to drilling fluids 15 years ago to enhance cuttings and wellbore stability.
