Abstract: A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet and a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The actuator and conveyor can be controlled remotely.

Abstract: Method of handling proppant at a well site using a plurality of modular proppant containers in which first and second modular proppant container in a filled state are removed from delivery transport vehicles and transferred to first and second cradle positions on a support structure using one or more heavy-duty handlers. Proppant is discharged by gravity feed from the outlet of the first and second modular proppant containers and directed to a hopper until the modular proppant containers are in an empty state.

Abstract: An apparatus to support a proppant container includes a frame to receive and support the proppant container. The frame has a top surface that receives and positions the proppant container in an elevated position. The apparatus also includes a box guide assembly positioned on the top surface a box guide assembly connected to the top surface of the frame for defining a cradle section having four corners. The box guide assembly including a box guide positioned at each of the corners. Each box guide has a corner member extending upwardly from the top surface along a peripheral edge of the frame and a guide member extending adjacent the corner member. The guide member include an inclined face for aligning the proppant container in the cradle section. The box guide assembly guides the proppant container into the cradle section when loaded onto the frame in the elevated position.

Abstract: A method is disclosed for storing and moving proppant. A supply of fracking proppant is provided at a remote location. A plurality of containers are provided to the desired location, each container having a top, a plurality of walls extending from the top and terminating at an outlet for discharge of proppant therefrom and a flow gate positioned adjacent the outlet to control flow of proppant from an interior volume of the container through the outlet. The plurality of containers are filled with fracking proppant at the remote location, then transported from the remote location to a well site location. The plurality of containers are staged at the well site location and the amount of proppant on hand at the well site location is tracked.

Abstract: An apparatus for the transport and storage of proppant has a container with a top wall, a pair of end walls and a pair of side walls. The pair of side walls extend between the pair of end walls. The container has a bottom discharge opening. The container includes a funnel extending from the pair of side walls and from the pair of and walls toward the bottom discharge opening. The funnel has sides extending in an angle of greater than 25° with respect to horizontal. The funnel includes a pair of side plates extending respectively from the pair of side walls toward the bottom discharge opening and a pair of end plates extending respectively from the pair of end walls toward the bottom discharge opening. Each of the side plates and the end plates is formed of a stainless steel material.

Abstract: Embodiments of the present disclosure include an apparatus to support a proppant container including a frame to receive and support the proppant container, the frame having a top surface that receives and positions the proppant container above a conveyor to carry proppant disposed thereon away from the proppant container. The apparatus also includes a box guide assembly positioned on the top surface including a corner assembly having two wall segments, and a guide member extending upwardly and positioned adjacent the corner assembly, the guide member including tapered portion of the guide member, the taper having a first width at a top portion of the guide member smaller than a second width at a bottom portion of the guide member. The tapered portion contacts and directs the proppant container to a desired location.

Abstract: A method of delivering proppant to a well site has the steps of transporting a load of proppant in a vessel to a desired location, moving the load of proppant from the vessel into a container so as to create a proppant-loaded container, unloading the proppant-loaded container into a pneumatic bulk trailer, and transporting the unloaded proppant in the pneumatic bulk trailer to well site. The container is placed onto a bed of a truck and moved in proximity to the vessel. The proppant-loaded container is placed onto a tilting mechanism and then tilted so that the proppant is discharged through a flow gate of a container into a hopper. The proppant in the hopper can then be conveyed to the pneumatic bulk trailer.

Abstract: A proppant discharge system includes a container having an outlet formed at a bottom thereof, a gate affixed at the outlet and positioned on the floor of the container so as to be movable between a first position covering the outlet to a second position opening the outlet, a support structure having the container positioned on the top surface thereof. The support structure has at least one actuator affixed thereto. The actuator is positioned so as to move the gate between the first position and the second position. The container has a cage affixed on the floor thereof in a position over the outlet. The gate is positioned within the cage and is movable by the actuator so as to open the gate so as to allow proppant to be discharged therefrom.
