ABSTRACT:
An assembly for use in a wellbore formed in an earth formation, comprising an expandable tubular element and an outer structure having first and second portions arranged at a distance from each other, the portions being restrained to the tubular element in a manner that the distance changes as a result of radial expansion of the tubular element, the outer structure further having a third portion arranged to move radially outward upon said change in distance between the first and second portions, wherein said radially outward movement of the third portion is larger than the radially outward movement of the tubular element as a result of radial expansion of the tubular element.
