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.

Abstract: A portable conveyor system receives and conveys particulate material to downstream equipment. The system includes a base frame, a material handling assembly carried on the base frame for depositing the material into the downstream equipment, and at least one adjustable feed conveyor to convey the material from a source onto the material handling assembly. The feed conveyor is movable in various manners relative to the base frame between a working position and a stored position. The material handling assembly includes a main conveyor assembly to convey material along the base frame from the feed conveyors to an elevating assembly at one end of the base frame. The elevating assembly is collapsible in height relative to the base frame for transport.

Abstract: A fluid storage tank has a base structure, perimeter columns extending upward from the base structure and a flexible bladder contained within the perimeter columns to define a boundary of the tank. The base structure is arranged to be supported on a supporting foundation to span a bottom of the tank. The upright columns are releasably coupled to the base structure and extend upward at circumferentially spaced apart positions about a perimeter of the tank in a working position of the columns. The upright columns are collapsible from the working position to a transport position in which the columns are arranged to be bundled alongside ne another. The flexible bladder is coupled to the upright columns and contains a fluid within the tank in the working position while being collapsible within the columns into the transport position.

Abstract: A collapsible storage system for flowable material, for example granular material, includes a base frame and an upper frame which is movable between a collapsed position and a working position spaced above the collapsed position. A plurality of storage silos are supported in a row, each including a hopper discharge cone on the base frame and a collapsible tubular wall assembly connected between the discharge cone and the upper frame. Redundant loading conveyors are provided in communication with the silos across the upper frame for loading and redundant unloading conveyors are provided in communication with the silos across the base frame.
