<p>The system has a production pipe (206) arranged inside an outer wall of a gas storage well (200). The production pipe is associated with a sealing system (210) fitted in an annular valve (212) provided with elastomer joints so as to guide pressurized gas between a surface and a chimney (220) situated at an inlet of the cavity. A protection pipe (230) i.e. tail pipe, is fixed to a cemented tubing (204) for being maintained in the chimney, independent from the production pipe and the sealing system. An independent claim is also included for a method for producing and storing gas in a cavity.</p> |
