Optimized recycling of drilling fluids by coordinating operation of separation units

Abstract

One system embodiment includes: an inlet sensor that measures a fluid quality of an input fluid stream; an arrangement of separation units operating to extract contaminants from the fluid stream; and a user interface (UI). Each separation unit produces a respective output fluid stream, exhibiting a performance that is impacted by a respective operating parameter, and has an outlet sensor that measures an output fluid stream quality. The UI receives fluid quality measurements from the inlet and the outlet sensors, responsively derives a performance value for each separation unit and an overall performance value for the arrangement, and displays each of the performance values. The UI may further set the operating parameter values to automate and optimize the operation of the arrangement for different drilling conditions. The fluid quality measurements may indicate contaminant concentrations, and the performance values may account for separation efficiency, energy consumption, reliability, and next service date.
