  • Patent number: 9862538
    Abstract: A mobile support structure (MSS) includes a frame structure for receiving modular silos, a base moveable between transportation and support configurations, and connectors coupling with the silos. A mobile erecting assembly includes a chassis, a lift structure rotatable between transportation and mounting orientations while engaged with a silo, an engagement structure movable between first and second positions while engaged with the silo, and an actuator to move the engagement structure and silo between the first and second positions. The silo is connected to the mobile erector assembly in the transportation orientation, and the mobile erector assembly is then aligned relative to the MSS, such as by engaging an alignment member of the mobile erector assembly with a chassis alignment post of the MSS. The mobile erector assembly is then operated to move the silo to the mounting orientation, and the silo is then coupled to the MSS.

  • Patent number: 9752389
    Abstract: A system and methodology facilitates the handling of oilfield material. The oilfield material is stored in at least one silo which enables use of gravity to feed the oilfield material to a blender or other suitable equipment. Each modular silo is transportable and may be engaged with a support structure via a pivot connection. Once engaged, the silo is pivoted to a raised, upright position on the support structure. The oilfield material is then moved to an interior of the silo, and gravity may be used to feed the oilfield material to a blender or other equipment in a controlled manner.

  • Publication number: 20170144831
    Abstract: A system for managing fiber on-site at an oilfield. The system includes a packing region and a corresponding region which both interface a bulk of the fiber simultaneously. However, the packing region is of a moving character and the corresponding region is of a substantially different character which may or may not be static in nature. Regardless, the difference in character between the adjacent regions allows for a substantially continuous manner of packing fiber. This may be particularly beneficial where the fiber is of a crimped nature or otherwise comparatively light or of low density as may be the case for certain downhole fracturing or cementing applications utilizing the fiber at the oilfield.
