摘要:
The present invention includes a method and apparatus for setting a liner in a wellbore and then expanding a screen in the wellbore in a single trip. In one aspect of the invention, a liner and expandable screen is provided with a slip assembly to fix the liner in the wellbore. An expansion tool and work sting is run into the wellbore in the liner. After the liner is set, the expansion tool is used to expand the screen. In another embodiment, an annular area between the expansion tool and work string is utilized in order to set the slips. Thereafter, cup packers used in forming the annulus are lifted from the liner prior to expanding the screen.
