Definitions

  • the present disclosure relates generally to the handling of dry bulk materials, and more particularly, to a soft-sided bulk material storage container for use in the storage, transportation and dispensation of such dry bulk materials.
  • high viscosity gels are used to create fractures in oil and gas bearing formations to increase production.
  • High viscosity and high density gels are also used to maintain positive hydrostatic pressure in the well while limiting flow of well fluids into earth formations during installation of completion equipment.
  • High viscosity fluids are used to flow sand into wells during gravel packing operations.
  • the high viscosity fluids are normally produced by mixing dry powder and/or granular materials and agents with water at the well site as they are needed for the particular treatment.
  • Systems for metering and mixing the various materials are normally portable, e.g., skid- or truck- mounted, since they are needed for only short periods of time at a well site.
  • the powder or granular treating material is normally transported to a well site in a commercial or common carrier tank truck. Once the tank truck and mixing system are at the well site, the dry powder material (bulk material) must be transferred or conveyed from the tank truck into a supply tank for metering into a blender as needed.
  • the bulk material is usually transferred from the tank truck pneumatically. More specifically, the bulk material is blown pneumatically from the tank truck into an on-location storage/delivery system (e.g., silo).
  • the storage/delivery system may then deliver the bulk material onto a conveyor or into a hopper, which meters the bulk material through a chute into a blender tub.
  • FIG. 1 is an isometric view of a soft-sided bulk material storage container, in accordance with an embodiment of the present disclosure

  • Bulk material handling systems are used in a wide variety of contexts including, but not limited to, drilling and completion of oil and gas wells, concrete mixing applications, agriculture, and others.
  • the disclosed embodiments are directed to systems and methods for efficiently moving bulk material into a blender inlet of a blender unit at a job site.
  • the systems may include a portable support structure used to receive one or more portable containers of bulk material and output bulk material from the containers directly into the blender inlet.
  • the disclosed techniques may be used to efficiently handle any desirable bulk material having a solid or liquid constituency including, but not limited to, sand, proppant, gel particulate, diverting agent, dry-gel particulate, liquid additives and others.
  • dry material e.g., sand, proppant, gel particulate, or dry-gel particulate
  • the bulk material is often transferred between transportation units, storage tanks, blenders, and other on-site components via pneumatic transfer, sand screws, chutes, conveyor belts, and other components.
  • a new method for transferring bulk material to a hydraulic fracturing site involves using portable containers to transport the bulk material.
  • the containers can be brought in on trucks, unloaded, stored on location, and manipulated about the site when the material is needed.
  • These containers generally include a discharge gate at the bottom that can be actuated to empty the material contents of the container at a desired time.
  • the containers are generally supported above a mechanical conveying system (e.g., moving belt, auger, bucket lift, etc.) prior to releasing the bulk material.
  • the discharge gates on the containers are opened to release the bulk material via gravity onto the moving mechanical conveying system.
  • the mechanical conveying system then directs the dispensed bulk material toward a desired destination, such as a hopper on a blender unit. This process can release a relatively large amount of dust into the air and result in unintended material spillage.
  • the mechanical conveying system is generally run on auxiliary power and, therefore, requires an external power source to feed the bulk material from the containers to the blender.
  • the material handling systems having the portable support structure disclosed herein are designed to address and eliminate the shortcomings associated with existing container handling systems.
  • the portable support structure may include a frame for receiving and holding one or more portable bulk material storage containers in an elevated position proximate the blender inlet (e.g., blender hopper or mixer inlet), as well as one or more gravity-feed outlets for routing the bulk material from the containers directly into the blender inlet.
  • the portable support structure may be transported to the well site on a trailer, unloaded from the trailer, and positioned proximate the blender unit.
  • the portable support structure may be a mobile support structure that is integrated into a trailer unit.
  • the portable support structure may be designed with an open space at one side so that the blender unit can be backed up until the blender inlet is in position directly under the gravity-feed outlet(s) of the support structure.
  • the disclosed portable support structure may provide an elevated location for one or more bulk material storage containers to be placed while the proppant (or any other liquid or solid bulk material used in the fluid mixtures at the job site) is transferred from the containers to the blender.
  • the support structure may elevate the bulk material storage containers to a sufficient height above the blender inlet and route the bulk material directly from the containers to the blender inlet. This may eliminate the need for any subsequent pneumatic or mechanical conveyance of the bulk material (e.g., via a separate mechanical conveying system) from the containers to the blender. This may improve the energy efficiency of bulk material handling operations at a job site, since no auxiliary power sources are needed to move the material from the containers into the blender inlet.
  • the portable support structure may simplify the operation of transferring bulk material, reduce material spillage, and decrease dust generation.
  • each container frame must be robust enough to carry the weight of its stack.
  • each frame is equipped with alignment pins to facilitate the stacking of the containers.
  • FIG. 1 illustrates a schematic diagram of a soft-sided bulk material storage container 10 in accordance with the present disclosure.
  • the container 10 includes a frame 12, which includes a top 14, bottom 16 and plurality of sides 18.
  • the frame is formed of a plurality of rigid bars 20, which in one exemplary embodiment may be formed of steel. As those of ordinary skill in the art will appreciate, however, alternative rigid materials may be used in the construction of the frame 12.
  • the grade/weight of steel or other rigid material utilized should be able to carry the weight of multiple containers such as when the containers are stacked.
  • a pair of parallel tubes 21 is attached to the bottom 16 of the frame 12 at generally opposite sides, as shown in FIG. 2.
  • the tubes 21 have a general rectangular cross-section and are designed to accommodate the forks of a forklift. This enables the containers 10 to be easily hoisted onto and off transportation units (not shown) and also moved around a well site.
  • the rigid bars 20 are formed at least on the sides into a cross-bar configuration. These cross-bars reinforce the frame 12. Unlike prior art bulk material storage containers, whose frames are made up of solid panels, frame 12 simply relies on the cross-bars to give it form and strength. This configuration results in a lighter- weight container 10 which has a greater capacity for storage of bulk material. Indeed, the reduction in material making up the frame 12 together with the use of a soft material for the storage containment structure 22 reduces the overall weight of the container by approximately 31% over prior art containers. This weight savings will allow an approximate additional 2,000 lbs. of dry bulk material to be transported in each container, which results in an approximate 5% increase over current capacity of existing conventional bulk material storage containers.
  • the fabrication expenses associated with the design of the present bulk material storage container 10 will also result in a significant reduction in the fabrication cost for the containers. It is estimated that by eliminating the conventional side panels and associated welding of same, that a reduction of approximately 100 hours of fabrication time will result in connection with the manufacture of the bulk storage material containers 10, in accordance with the present disclosure.
  • An inlet 24 is located in the top 14 of the frame 12.
  • the inlet 24 is formed by two orthogonal pairs of parallel cross bars.
  • One or more hatches 26 may be mounted to the inlet 24 by a pair of hinges 28 and 30.
  • the pair of hinges 28 and 30 enables the hatch to swing between an open position and a closed position. In the open position, dry bulk material can be disposed into the container 10 through the opening 24. In the closed position, the dry bulk material is contained within the container 10 thereby preventing it from being lost to the environment or exposed to undesired moisture. Bulk material loss can be an issue during transport and in windy environments.
  • the hatch 26 assists in the containment of the bulk material storage.
  • the container 10 is also formed with a plurality of alignment pins 25 disposed on the top 14 of the frame 12 and an associated plurality of alignment recesses 27 disposed on the bottom of the frame 12.
