Abstract
A method for use with a subterranean well can include releasing flow conveyed plugging devices into the well, each of the plugging devices including a body and, extending outwardly from the body, at least one of lines and fibers, and the plugging devices blocking flow through respective openings in the well. Another method can include perforating a zone, releasing a set of flow conveyed plugging devices into the well, each of the plugging devices including a body and, extending outwardly from the body, at least one of lines and fibers, the set of plugging devices blocking flow through respective perforations in the zone, perforating another zone, releasing another set of the flow conveyed plugging devices into the well, and the second set of plugging devices blocking flow through respective perforations in the second zone.
