Abstract: A system for managing proppant inventory includes a plurality of silos, each silo having a sensor to sense a proppant level of proppant stored therein. The system also determines an amount of proppant that is expected to become available, and automatically creates and sends an order to request additional proppant upon determining that the combination of the proppant level within the at least one of the plurality of silos and the amount of proppant that is expected to become available is less than a predetermined threshold or expected to fall below the predetermined threshold. The system also automatically selects one or more of the plurality of silos to unload the additional proppant into based upon the proppant level in each of the plurality of silos at the time of unloading the additional proppant and at least one of a user preference parameter or historical data from a previous operation.
