Method of delivering, storing, unloading, and using proppant at a well site

A method of handling fracking proppant at a well site, the method comprising:

• removing a first single proppant container that contains fracking proppant from a first road transport trailer that has only the first single proppant container positioned thereon and when the trailer is positioned adjacent a well site at a location where hydraulic fracking is to be performed, the first single proppant container being modular and the removing being performed by one or more forklifts that engage a lower portion of the first single proppant container via fork receptacles of the single proppant container;
• transferring, after removal from the first road transport trailer, the first single proppant container to a first cradle position on a support structure positioned at the well site so that the first single proppant container is positioned to discharge by gravity feed the fracking proppant therefrom;
• removing a second single proppant container that contains fracking proppant from a second road transport trailer that has only the second single proppant container positioned thereon after removing the first single proppant container, the second single proppant container also being modular and the removing thereof also being performed by the one or more forklifts so that the first and second single proppant containers provide a plurality of proppant containers that contain fracking proppant to the well site, each of the first and second proppant containers having an outlet positioned at a bottom thereof with slanted lower inner wall portions positioned to direct the fracking proppant toward the outlet, each of the first and second proppant containers having a closed and substantially rectangular upper proppant containing portion, the slanted lower inner wall portions being positioned to underlie the upper proppant containing portion and having proppant also positioned therein, a pair of vertically-extending end walls and a pair of vertically-extending side walls defining the closed and substantially rectangular upper proppant containing portion, a frame including a plurality of structural support members positioned along end portions of the end walls and side walls to enhance support of the end walls and the side walls when the proppant container is full of fracking proppant;
• transferring, after removal from the second road transport, the second single proppant container to a second cradle position on the support structure positioned at the wall site so that each of the first and second proppant containers is positioned to discharge by gravity feed the fracking proppant therefrom, wherein the first and second cradle positions are in a side by side, substantially horizontally extending direction that correspond to the first and second proppant containers being positioned in a side-by-side arrangement when transferred thereto and when positioned on the support structure;
• and
• discharging by gravity feed the fracking proppant contained within each of the first and second proppant containers when positioned on the support structure and within the first and second cradles from the outlet positioned at a bottom of each of the plurality of proppant containers.
