Abstract: A production system for producing hydrocarbons from a subterranean reservoir includes a wellhead including a housing and a head. The housing has a central axis, an upper end, a lower end, and an inner surface. The inner surface defines a passage extending axially through the housing. In addition, the inner surface of the housing includes an annular recess positioned between the upper end and the lower end. The housing also includes a first production port extending radially through the housing. Further, the system includes a casing hanger disposed within the housing. The casing hanger has an upper end, a lower end, an outer surface, and a through bore extending from the upper end to the lower end. The casing hanger also includes a plurality of circumferentially-spaced ports extending radially through the casing hanger from the through bore to the annular recess of the housing.
