<p>A method for sealing a hole in a tubular in a wellbore comprising : (A) locating the tubular patch adjacent the hole; (B) (i) plastically expanding a first portion of the tubular patch above the hole into annular sealing engagement with the tubular to form a first annular seal and (ii) plastically expanding a second portion of the tubular patch below the hole in the tubular into annular sealing engagement with the tubular or the open hole to form a second annular seal thereby sealing the hole in the tubular. The patch may be a corrugated tube prior to expansion in order to pass through restrictions and may have a section with an increased wall thickness including a resilient seal.</p>
