Abstract

A device (1) for forming a barrier in an annulus (5) of a well (11). The device comprises an injection tool (20) adapted to introduce a polymeric hardening liquid in through an opening in the annulus (5), and a pump unit (26) adapted to provide pressure to said liquid so that the liquid is introduced into the opening in the annulus with a controllable pressure. The device comprises a control unit (30) adapted to control the pump unit (26) so that said liquid is provided into the opening with an initial pressure at a start-up phase of introducing the liquid into the opening and a final pressure at a close-down phase of introducing the liquid into the opening, wherein the final pressure is higher than the initial pressure.
