Abstract: Described is a method for quantifying and tracking an amine-based shale inhibitor in a drilling fluid through UV-visible spectroscopy. A correlation is determined between varying concentrations of an amine-based shale inhibitor in a water-based drilling fluid sample and an ultraviolet (UV)-visible absorption intensity. A calibration plot is generated based on the correlations. Samples of a circulating drilling fluid having an unknown concentration of amine-based shale inhibitor are obtained. Using the calibration plot, the concentration of amine-based shale inhibitor in the samples of the circulating drilling fluid is estimated.

Abstract: Described is a method for assessing quality of an amine-based shale inhibitor in drilling fluid. A relationship between a concentration of the amine-based shale inhibitor in a drilling fluid and turbidity is established by preparing drilling fluid solutions with varying concentrations of the amine-based shale inhibitor, allowing the drilling fluid solutions to form precipitates, and analyzing turbidity of the drilling fluid solutions. A sample of a drilling fluid with an unknown concentration of amine-based shale inhibitor is obtained. Using the established relationship, a concentration of the amine-based shale inhibitor in the sample of the drilling fluid is estimated.
