  • Method and system for radially expanding a tubular element and directional drilling
    Patent number: 9464481
    Abstract: The invention relates to a system and method for radially expanding a tubular element. The method comprises the steps of bending the tubular element radially outward and in axially reverse direction so as to form an expanded tubular section extending around an unexpanded tubular section, wherein bending occurs in a bending zone; increasing the length of the expanded tubular section by pushing the unexpanded tubular section in axial direction relative to the expanded tubular section; operating a drill string, which extends through the unexpanded tubular section and is provided with a drill bit at a downhole end thereof, to drill a borehole; and operating directional drilling means, which are coupled to the drill string, to deviate the borehole and direct the borehole along a predetermined path.
