Flow control in subterranean wells
First Claim
1. A method of controlling flow in a subterranean well, the method comprising:
- introducing a plugging device into the well, the plugging device comprising a plurality of lines extending outwardly from a body, and the body comprising a knot;
conveying the device by flow in the well; and
sealingly engaging the knot with an opening formed through a wall of a tubular string in the well, thereby preventing flow through the opening, the knot being too large to pass through the opening.
