Flow control in subterranean wells
A flow conveyed device for use in a well can include a body and a plurality of lines joined to the body, each of the lines having a lateral dimension that is substantially smaller than a size of the body, and each of the lines including fibers. A method of controlling flow in a well can include a device introduced into the well being conveyed by flow in the well, and the device including a plurality of lines extending outwardly from a body. Each of the lines may include fibers. A system for use with a well can include a flow conveyed device conveyed through a tubular string by flow in the tubular string, the flow conveyed device including a body with a plurality of lines extending outwardly from the body, the body including at least one knot.
1. A flow conveyed device for use in a subterranean well, the device comprising:
a body; and
a plurality of lines extending outwardly from the body, each of the lines having a lateral dimension that is substantially smaller than a size of the body, wherein each of the lines comprise multiple fibers, and wherein the fibers are configured to increase fluid drag during conveyance of the device in the subterranean well.
2. The device of claim 1 , wherein the lines are retained by a retainer.
3. The device of claim 2 , wherein the retainer degrades in response to passage of a predetermined period of time.
4. The device of claim 2 , wherein the retainer degrades in response to exposure to a predetermined fluid.
5. The device of claim 2 , wherein the retainer degrades in response to exposure to a predetermined chemical composition.
6. The device of claim 2 , wherein the retainer degrades in response to exposure to a predetermined temperature.
7. The device of claim 2 , wherein the retainer degrades in response to exposure to radiation.
8. The device of claim 1 , wherein the lines comprise ropes.
9. The device of claim 1 , wherein the body comprises at least one knot.
10. The device of claim 1 , wherein the body comprises a degradable material.
11. The device of claim 1 , wherein the fibers comprise a degradable material.
