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.
