ABSTRACT:
Alternate path multilateral production/injection. In a described embodiment, a system for drilling and completing a well having intersecting first and second wellbores comprises a casing string positioned in the first wellbore; and at least one apparatus interconnected in the casing string. The apparatus includes a mandrel having intersecting first and second passages formed therein. The first passage extends longitudinally through the mandrel and is in fluid communication with an interior of the casing string. The second passage extends laterally relative to the first passage and is configured for drilling the second wellbore therethrough. The mandrel further includes at least one third passage or alternate path extending longitudinally in the mandrel.
