Annular Barrier System With Flow Lines
Abstract: The present invention relates to an annular barrier system (100) connected with a well head (40) via a well tubular structure (3) comprising a first annular barrier (1) and a second annular barrier (21) to be expanded in an annulus (2) between the well tubular structure and an inside wall (4) of a casing (20) or a borehole (5) downhole for providing zone isolation between a first zone (8) and a second zone (9) each annular barrier comprising a tubular part (6) extending in a longitudinal direction for mounting as part of the well tubular structure an expandable sleeve (7) surrounding the tubular part and defining a space (13) an opening (11) for letting fluid into the space to expand the sleeve and a first connection part (15) and a second connection part (16) connecting the expandable sleeve with the tubular part and wherein the first connection part is arranged nearest to the well head the system further comprising a flow line (17) fluidly connecting the well head with the opening for supplying fluid to the opening for expanding the expandable sleeve. Furthermore the present invention relates to a well completion system and method.
