A method is provided of radially expanding a tubular element extending into a wellbore formed in an earth formation, the method comprising inducing the wall of the tubular element to bend radially outward and in axially reverse direction so as to form an expanded tubular section extending around a remaining tubular section of the tubular element, wherein said bending occurs in a bending zone of the tubular element, and increasing the length of the expanded tubular section by inducing the bending zone to move in axial direction relative to the remaining tubular section. One of the tubular element and the wellbore wall is provided with at least one seal member arranged to induce sealing of the expanded tubular section relative to the wellbore wall.
