Abstract

Claims (61)

7. The method of claim 6 , further comprising stacking at least one of the first and second modular proppant containers on another modular proppant container queued in the stacking zone.

8. The method of claim 1 , further comprising:

transferring the first modular proppant container in the empty state from the first cradle position on the support structure using the one or more heavy-duty handlers;

placing the first modular proppant container in the empty state onto a first return transport vehicle using one or more heavy-duty handlers;

transferring the second modular proppant container in the empty state from the second cradle position on the support structure using the one or more heavy-duty handlers; and

placing the second modular proppant container in the empty state onto a second return transport vehicle using one or more heavy-duty handlers.

9. The method of claim 8 , further comprising:

queueing the first modular proppant container in a stacking zone at the well site after transferring the first modular proppant container in the empty state from the first cradle using the one or more heavy-duty handlers; and

queueing the second modular proppant container in the stacking zone at the well site after transferring the second modular proppant container in the empty state from the second cradle using the one or more heavy-duty handlers.

10. The method of claim 9 , further comprising stacking at least one of the first and second modular proppant containers in the empty state on another modular proppant container queued in the stacking zone.

11. The method of claim 8 , further comprising:

returning the first modular proppant container from the well site in the empty state to a fill site on the first return transport vehicle; and

receiving the second modular proppant container at the well site in the full state from the fill site on the second return transport vehicle.

12. A method of handling proppant at a well site comprising:

providing a plurality of modular proppant containers, each of the plurality of modular proppant containers having a wall portion, a funnel portion extending beneath the wall portion and terminating at an outlet, and a frame including a leg post at each corner of the wall portion and a plurality of structural support members extending between the leg posts along the wall portion to structurally-enhance modular proppant container, where each of the plurality of modular proppant containers are in a filled state with proppant stored therein;

removing a first modular proppant container in the filled state from a first delivery transport vehicle using one or more heavy-duty handlers;
