Abstract

The invention provides a wellbore system comprising an expandable tubular element arranged in a wellbore formed in an earth formation whereby an annular space is present between the tubular element and a wall surrounding the tubular element. The tubular element is provided with sealing means for sealing the annular space, wherein the sealing means includes a foldable wall section of the tubular element. The foldable wall section has a reduced bending stiffness relative to a remainder wall section of the tubular element and is deformable from an unfolded mode to a folded mode by application of a compressive folding force to the tubular element. The foldable wall section when in the folded mode comprises at least one annular fold extending radially outward into said annular space. The wellbore system further comprises a folding device for applying said folding force to the tubular element.
