Abstract

This paper presents the results of experimental viscosity determination of oilfield fluids using a microfluidic chip with radial channels fabricated by an original technology. The method is based on the hydraulic resistance principle, where the test fluid and a reference fluid are simultaneously introduced into the chip at equal volumetric flow rates and distributed through an array of identical channels. The relative viscosity is determined by the ratio of the number of channels filled by each fluid, which eliminates the need for calibration. A custom chip topology optimized for the analysis of oilfield fluids has been proposed and implemented. Distilled water and aqueous glycerol solutions with known viscosity were used as reference fluids. Three oil samples differing in density and viscosity were investigated. It is shown that the proposed chip configuration enables rapid analysis with small sample volumes. The viscosity measurements obtained using the microfluidic method are in good agreement with the data from rotational rheometry. It is shown that the developed microfluidic viscometer with radial channels is a promising tool for rapid viscosity monitoring of oilfield fluids
