A first tubular (2010) is suspended along a lower portion of a cased well (2005) by means such as a slip mechanism (2035) and overlaps with a portion of the casing 2005) . A second tubular (2025) is lowered into a wellbore (2000) in the direction indicated by arrow (2045, figure 20A) by means such as on a run-in string (not shown) and includes an expansion cone (2050) to form a PBR proximate the upper end of the first tubular (2010) . The second tubular (2025) also includes a plurality of seal sets (2055) and an anchor member (2060) . This method is particularly useful in forming a monobore tieback and allows the first tubular (2010) and the second tubular (2025) to have approximately the same diameter along their length, causing the path for fluid flow through the tubulars to remain substantially consistent along their length. |
