Method and system for accessing subterranean zones from a limited surface area

摘要

A method and system for accessing subterranean zones from the surface includes a substantially vertical well bore extending from the surface to a target zone, and an articulated well bore extending from the substantially vertical well bore to the target zone. The articulated well bore diverges from the substantially vertical well bore between the surface and the target zone. The system also includes a well bore pattern extending from the articulated well bore in the target zone operable to collect resources from the target zone. The system also includes a subsurface channel operable to communicate resources from the well bore pattern to the substantially vertical well bore. The system further includes a vertical pump disposed in the substantially vertical well bore and operable to lift resources collected in the substantially vertical well bore to the surface.
