Abstract
A plugging device can include a body configured to engage and substantially block flow through a passageway, and the body including a winding of at least one of fiber, line, rope, tube, filament, film, fabric, mesh and weave. A method of plugging a passageway can include releasing a plugging device into a fluid flow, thereby causing the plugging device to be carried by the fluid flow to the passageway, the plugging device including a body formed with at least one winding, and the plugging device engaging the passageway and thereby blocking the passageway. A well system can include a plugging device conveyed through a tubular string by fluid flow in the well, the plugging device including a body configured to engage and resist extrusion through a passageway in the well, the body including a winding, and in which the winding substantially blocks the fluid flow through the passageway.
