Abstract

A wellbore completion includes a housing and a mandrel. The housing is coupled with a wellbore string disposed within a well that includes a first wellbore and a second wellbore extending from the first wellbore. The housing resides at the juncture and includes fluid port, a first fluid inlet fluidly coupled with the first wellbore, and a second fluid inlet fluidly coupled with the second wellbore. The mandrel includes a first fluid conduit and a second fluid conduit and is rotatable to position the mandrel in a first position, in which the first fluid conduit is aligned with the fluid port and the first fluid inlet to open a fluid pathway from the first wellbore, or a second position, in which the second fluid conduit is aligned with the fluid port and the second fluid inlet to open a second fluid pathway from the second wellbore.
