Abstract

A system for accessing a subterranean zone from the surface includes a first, second and third entry well bore extending from the surface, the first, second and third entry well bores (15) located on the same drilling pad (92) at the surface. A slanted well bore (20) extends from each of the entry well bores to the subterranean zone (22). A substantially horizontal drainage pattern extends from the slanted well bores into the subterranean zone.
