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/cm3, 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.
Agrégat de fibres comprenant des fibres polymères organiques, lesdites fibres polymères organiques ayant une longueur moyenne allant de 2 à 20 millimètres, un diamètre moyen pouvant atteindre 100 micromètres, et comprenant au moins 75 pourcent en volume plein de l'agrégat de fibres. Ledit agrégat de fibres a une densité apparente non restreinte d'au moins 0,05 g/cm3 et au moins 85% en volume de l'agrégat de fibres se dissocie pour fournir des fibres dispersées. Les agrégats de fibres sont utiles, par exemple, pour le contrôle du retour dans les trous de forage et les réservoirs.
