摘要 |
<p>There is described a method of lining a wellbore including deploying a bottom hole assembly (BHA) into the wellbore using a conveyance. The BHA includes a 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.</p> |
