Abstract
A fluid seal assembly having a sleeve disposed circumferentially around a downhole tool. First and second fasteners extend circumferentially around the sleeve proximate respective first and second ends of the sleeve. The first and second fasteners may comprise a shape-memory alloy that, in response to a temporarily increased temperature, have caused the first and second fasteners to circumferentially compress the sleeve against an outer surface of the downhole tool.
