Title: Method and system for fixing an element in a borehole

Abstract: A method is provided of fixing at least one element, preferably a sensor or a valve, in a borehole formed in an earth formation. The method comprises positioning each element in the borehole, positioning a swellable body in the borehole, the swellable body being susceptible of swelling upon contact with a swell fluid, wherein the swellable body is arranged to press the element against a wall of the borehole upon swelling of the swellable body, and allowing the swell fluid to contact the swellable body thereby inducing the swellable body to swell and to press the element against said wall of the borehole.
