1. A method of controlling flow in a subterranean well, the method comprising:
- introducing a device into the well, the device comprising a plurality of fibers extending outwardly from a body, wherein the fibers are joined together and form one or more lines extending outwardly from the body;
conveying the device by flow in the well; and
a material of the body engaging an opening in the well and degrading in the well in response to at least one of the group consisting of;
passage of a predetermined period of time in the well, exposure to a predetermined temperature in the well, exposure to a predetermined fluid in the well, exposure to radiation in the well and exposure to a predetermined chemical composition in the well.
