Correcting offsets in wellbore tubulars
Abstract:
A system for positioning an inner tubular within an outer tubular. The outer tubular is inserted in a wellbore and has a first central axis. The inner tubular defines an inner passage of the outer tubular and is inserted in a wellbore. The inner tubular has a second central axis that is offset from and parallel to the first central axis. A flange is attached at an uphole end of the outer tubular and encircles an outer circumference of the inner tubular. The flange has a third central axis that is in-line with the second central axis. A wellhead housing is positioned at an uphole end of the flange and encircles the outer circumference of the inner tubular. A casing hanger is positioned within the wellhead housing and has an interference with the wellhead housing. The casing hanger is frictionally attached to the inner tubular.
