Centrifugal platform and device for rapid analysis of oilfield fluids

A microfluidic device for evaluation of an organic/inorganic scale inhibitor comprising:

• a substrate mountable to a disc for rotation about an axis, the microfluidic device having a proximal end and a distal end, the substrate defining a sample reservoir, a solvent reservoir, an inhibitor reservoir, and a precipitant reservoir at the proximal end and an analysis chamber at the distal end in fluid communication with the sample, solvent, inhibitor, and precipitant reservoirs,
• wherein the substrate is configured to direct one or more of fluids in the sample reservoir, solvent reservoir, inhibitor reservoir, and precipitant reservoir radially outwardly towards the analysis chamber under the influence of centrifugal force when the microfluidic device rotates, such that a mixture of at least two of the fluids from the sample, solvent, inhibitor and precipitant reservoirs is configured to be analyzed in the analysis chamber.
