Abstract
A system and method for lining a section of a wellbore with an expandable tubular element. The system comprises an elongate drill string having a force multiplier near a lower end thereof, which is housed within the expandable tubular element. An expander for expanding the tubular element is arranged at a lower end of the force multiplier. Anchoring means are provided at the exterior of the tubular element for anchoring the tubular element in the wellbore. Pulling the expander through the expandable tubular using the force multiplier may be combined with pulling the drill string upwards. A sudden drop of the hydraulic pressure in the force multiplier drops will confirm fixation of the anchoring means in the wellbore wall.
