Abstract
A method of completing a subterranean well and associated apparatus therefor provide efficient operation and convenience in completions where production of fluids from a lateral wellbore and a parent wellbore is desired. In one disclosed embodiment, the invention provides a method whereby a tubular member may be extended from a parent wellbore into a lateral wellbore, without the need of deflecting the tubular member off of a whipstock or other inclined surface. The tubular member may be previously deformed and initially constrained within a housing, so that as the tubular member extends outwardly from the housing, the tubular member is permitted to deflect laterally toward the lateral wellbore.
Claims29
A method of completing a subterranean well, the method comprising the steps of:
- drilling first and second wellbore portions, the second wellbore portion intersecting the first wellbore portion;
- installing a casing internally through the intersection of the first and second wellbore portions;
- installing a first liner in the casing within the second wellbore portion, the liner having a first seal surface attached thereto;
- providing a first assembly including a first packer, a tubular structure attached to the first packer, an orienting profile attached to the tubular structure, a second seal surface attached to the tubular structure, and a whipstock releasably attached to the first packer;
- positioning the first assembly in the second wellbore portion, the whipstock being proximate the intersection of the first and second wellbore portions;
- sealingly engaging the first and second seal surfaces;
- and
- setting the first packer in the second wellbore portion.
