Method for determination of amine-based additives in drilling fluid filtrates

摘要: The invention concerns a method for determining the presence and quantity of an amine-based additive in fluids, particularly aqueous fluids used hydrocarbon recovery such as drilling drill-in completion like. It was discovered that, after isolating additive, amount clay stabilizer is linearly dependent upon spectrometric count its peak fluorescent spectrum. reproducible not bothered by lignosulfonate and/or lignite which interferes with conventional methods.
