Abstract

The present invention relates to a downhole completion system for being arranged in a wellbore, comprising several casing sections having a casing length of 10-14 metres mounted as one well tubular metal structure by means of casing collars, wherein a number of the several casing sections each comprises at least three annular barriers each comprising an expandable metal sleeve configured to be expanded to abut the wellbore, the annular barriers of each casing section having a common longitudinal extension of at least 50% of the casing length. The present invention also relates to a downhole method for completing a well having a wellbore.
