Abstract: The present invention generally relates to an apparatus and method for expanding an expandable tubular assembly in a borehole. In one aspect, a system for expanding a tubular (560) having an anchor portion (550) in a borehole is provided. The system includes a running tool (535) configured to position the tubular in the borehole. The running tool including a first expander (520) configured to activate the anchor portion by expanding the tubular (525) to a first diameter. The system further includes a second expander (540) configured to expand the tubular (525) to a second larger diameter, wherein the second expander (540) is movable between a retracted position and an expanded position. In another aspect, a method of expanding a tubular having an anchor portion in a borehole is provided.

Abstract: The present invention generally relates to an apparatus and method for expanding an anchoring device in a borehole. In one aspect, an anchoring device is provided. The anchoring device includes an expandable tubular. The anchoring device further includes a plurality of bands disposed on an outer surface of the expandable tubular. Each band is attached to the tubular at a first connection point and a second connection point, wherein each band is configured to bow radially outward as the expandable tubular shortens in length in response to the expansion of the tubular. In a further aspect, a method of attaching an anchoring device in a borehole is provided.

Abstract: A method of lining a wellbore includes deploying a BHA into the wellbore using a conveyance. The BHA includes setting tool, an anchor, and an expandable tubular. The method further includes pressurizing a bore of the setting tool, thereby releasing the anchor from the setting tool. The method further includes pulling the conveyance, thereby: extending the anchor into engagement with a casing of the wellbore, pulling an expander of the setting tool through the expandable tubular, and expanding the tubular into engagement with an open and/or cased portion of the wellbore and retracting the anchor.

Abstract: ANCHOR FOR USE WITH EXPANDABLE TUBULAR A method of lining a wellbore includes deploying a BHA (100) into the wellbore (101) using a conveyance (114). The BHA (100) includes a setting tool (50), an anchor (1), and an expandable tubular (110). The method further includes pressurizing a bore of the setting tool (50), thereby releasing the anchor (1) from the setting tool (50). The method further includes pulling the conveyance (114), thereby: extending the anchor (1) into engagement with a casing (102) of the wellbore (101), pulling an expander (112) of the setting tool (50) through the expandable tubular (110), and expanding the tubular (110) into engagement with an open and/or cased portion of the wellbore (101) and retracting the anchor (1). 5500300v1:PRW 8 '18 19 - 227 227s 229 s. 260r 112 260f FIG. 2A FIG. 2B
