Abstract
An example well system including a drill string extending from a surface location into a wellbore and defining an annulus between the drill string and the wellbore, a fluid circuit extending through the drill string to a bottom of the wellbore and back to the surface location within the annulus, and further extending back to the drill string from the annulus, and one or more flow imaging devices in fluid communication with the fluid circuit to monitor the wellbore fluid and track a real-time particle size distribution (PSD) of one or more particulates suspended within the wellbore fluid.
