Abstract
Fiber aggregate comprising organic polymeric fibers, wherein the organic polymeric fibers have an average length in a range from 2 to 20 millimeters, an average diameter up to 100 micrometer, and comprise at least 75 percent by solid volume of the fiber aggregate, wherein the fiber aggregate has an unrestrained bulk density of at least 0.05 g/cm, and wherein at least 85% by volume of the fiber aggregate disassociates to provide dispersed fibers. The fiber aggregates are useful, for example, for flowback control in wellbores and reservoirs.
