ABSTRACT:
Disclosed is an improved method and apparatus for providing selective access to either a main well or a lateral well extending from the main well. A sleeve assembly installed in the junction of a main and lateral well includes a housing with a side window and a slidable internal sleeve for locating in either an "up" position or a "down" position. When the internal sleeve is "up", the side window is uncovered so that downhole tools select the main wellbore by gravity. When the internal sleeve is "down", it covers the side window and guides downhole tools into the lateral well. When first making a lateral well, the lateral wellbore may be lined through a window in the main wellbore casing and a window opened in the wall of the lateral wellbore liner, in vertical alignment with the main well flow conductor. A sleeve assembly installed in the lateral wellbore liner, proximate the liner window includes a housing with a window and a slidable internal sleeve for locating in either an "up" position or a "down" position. When the internal sleeve is "up", the lateral liner window is uncovered so that downhole tools select the main wellbore by gravity. When the internal sleeve is "down", it covers the lateral liner window and guides downhole tools into the lateral well.
