Abstract
An apparatus and method for connecting a lateral well bore to a vertical well bore using a tieback liner while providing full bore access in the vertical well bore casing. The tieback liner is rotationally aligned with respect to a window of the casing by locating a key slot formed above the window and longitudinally aligned by using a no-go device to locate the bottom edge of the window. The tieback liner includes a snap sleeve that extends into a window of the main well bore casing and connects the tieback liner to the casing. The section of the casing receiving the snap sleeve is of a larger inner diameter than the other sections of casing. The connection between the tieback liner and casing prevents the tieback liner from rotating, tilting, or moving laterally with respect to the casing. The connection imparts significant resistance to formation loading applied at the junction.
