A well system includes at least two well bores extending from a surface to a subterranean zone. Each of the two well bores is used to form a well bore pattern for the subterranean zone that intersects the other well bore and transports fluid from the subterranean zone to the other well bore for production to the surface. In addition, each of the two well bores is operable to collect fluids transported to the well bore by the well bore pattern formed through the other well bore for production to the surface.
