ABSTRACT:
Annular packer (2) arranged on the outside of a production tubing (4) said packer comprises a core (12) comprising elastic polymer swelling by absorption of hydrocarbons. The core (12) may be surrounded by an external mantle of rubber (10), which is permeable to hydrocarbons and may be equipped with a reinforcement (11). The core (12) swells by absorption of hydrocarbons and the packer (2) expands thus in order to seal the annular space (5) between the production tubing (4) and the well wall (6).
