Abstract

Methods and systems for controlling proppant concentration in a hydraulic fracturing slurry include measuring volumetric flow rates of fracturing fluid input to a blender and hydraulic fracturing slurry output from the blender, using these measured values to calculate a volumetric flow rate of proppant input, a slurry density and/or a slurry volume fraction, adjusting first and second valves to control rates of fluid and proppant delivery to the blender and re-measuring the volumetric flow rates and recalculating until target values of volumetric flow rate of proppant input, slurry density and/or slurry volume fraction are achieved.
