Abstract (en)
The present invention relates to a device (11) of a part of a completion string arranged in a well (A), said well being lined with a casing or open hole, comprising a tubular conduit (12) designed to be placed within said well and comprising at least one expandable part (20) along its length, said part being radially expandable under the action of fluid pressure so as to be applied tightly against the inner wall of the well or casing. The wall (124) of said tubular conduit is of reduced thickness along the length of the expandable part, and the expandable part (20) has an inner diameter smaller than the tubular conduit outer diameter when unexpanded.
