METHOD AND SYSTEM FOR ACCESSING SUBTERRANEAN DEPOSITS FROM THE SURFACE

摘要

A method for accessing a subterranean zone from the surface by drilling substantially vertical well bores from the surface to the subterranean zone. An articulated well bore is drilled from the surface to the subterranean zone where the articulated well bore is horizontally offset from the vertical well bores at the surface but intersect one of them at a junction proximate to the subterranean zone. A substantially horizontal drainage pattern is drilled such that it extends from the junction into the subterranean zone.
