| 摘要 |
A method is provided of radially expanding a tubular element (4) extending into a wellbore formed in an earth formation, comprising the steps of arranging an expander (8) in the tubular element (4), the expander (8) being operable to exert a radial force to the inner surface of the tubular element (4), and radially expanding the tubular element by pressurising the interior of the tubular element (4) and simultaneously operating the expander (8) to exert said radial force to the inner surface of the tubular element. The expander (8) is operated to exert said radial force to the inner surface of the tubular element (4) independently from pressurising the interior of the tubular element.
