Correcting offsets in wellbore tubulars

A method comprising:

• providing a blow out preventer;
• providing a wellhead housing;
• providing an inner tubular and an outer tubular that encircles the inner tubular, the inner tubular having a fixed offset from the outer tubular;
• removing the blow out preventer;
• cutting the inner tubular to a first specified height above the wellhead housing;
• cutting an outer tubular to a second specified height lower than the first specified height;
• positioning a flange around the inner tubular and atop an uphole end of the outer tubular;
• positioning a corrected wellhead housing atop the flange;
• inserting a casing hanger into the corrected wellhead housing, the casing hanger encircling the inner tubular, the casing hanger comprising casing slips and a seal assembly;
• welding the flange to an outer surface of the outer tubular;
• welding the corrected wellhead housing to the flange;
• and
• energizing the seal assembly.

A method comprising:

• providing a blow out preventer;
• providing a wellhead housing;
• providing an inner tubular encircled by an outer tubular, the outer tubular having a first central axis, the inner tubular having a second central axis offset and parallel to the first central axis;
• removing the blow out preventer;
• cutting the inner tubular to a first specified height above the wellhead housing;
• cutting the outer tubular to a second specified height lower than the first specified height;
• attaching, by a flange, a corrected wellhead housing to the inner tubular, the flange having a third central axis that is in-line with the second central axis, the corrected wellhead housing having a fourth central axis that is in-line with the second central axis;
• inserting a casing hanger within the corrected wellhead housing, the casing hanger comprising casing slips and a seal assembly;
• and
• supporting the inner tubular, at least partially, by the casing hanger positioned within the corrected wellhead housing and encircling the inner tubular, the casing hanger having a fifth central axis that is in line with the second central axis.
