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.

Abstract: The invention provides a system for lining a wellbore. The system comprises an expandable tubular element arranged in the wellbore, the tubular element having a first end part and a second end part whereby the second end part extends into a tubular wall located in the wellbore. An expander is arranged to radially expand the tubular element by movement of the expander through the tubular element in a direction from the first end part to the second end part, said direction defining an expansion direction. The system further comprises an anchor arranged to anchor said second end part to the tubular wall in a manner that the anchor substantially prevents movement of said second end part in the expansion direction and allows movement of said second end part in the direction opposite to the expansion direction.

Abstract: The present invention provides a system for anchoring an expandable tubular to a borehole wall. The system comprises a support member having a first end fixed relative to the outside of the tubular and a second end comprising a ramping surface. An anchor member has a first end fixed relative to the outside of the tubular and a second end extending toward the support member, said second end being movable relative to the outside of the tubular. Said support member includes a ramp surface that tapers in the direction of said anchor member. Expansion of the portion of the expandable tubular between the first support end and the first anchor end causes the axial device length to shorten, wherein the difference in length is sufficient to cause the second anchor end to move radially outward and engage the borehole wall as a result of engagement with said ramping surface.

Abstract: An automated method for forge welding tubulars including heating the tubular ends to be joined in a welding chamber while the heated tubular ends are maintained aligned and parallel relative to each other and at a small spacing, whereupon the heated tubular ends are pressed together while a reducing shield gas is injected into the chamber. The positions of the tubular ends are monitored by cameras which are coupled to a pyrometric and position monitoring system which automatically adjusts the position of the tubular ends relative to each other and the heat supplied to the tubular ends during the heating step until the tubular ends have reached a predetermined temperature, whereupon the tubular ends are moved towards each other along a distance which exceeds the spacing monitored between the tubular ends during the heating step with a selected extra distance, such that the tubular ends are firmly pressed against each other and the amount of external and/or internal upset of the tubular ends in the welding zone is limited to an acceptable level.
