SYSTEM AND METHOD FOR MULTIPLE WELLS FROM A COMMON SURFACE LOCATION

摘要

A system for accessing a subterranean zone (24) from an entry well (12) including an entry well (12) extending from the surface (22). The entry well (12) has a substantially vertical portion. One or more drainage wells (14) extend from the entry well (12) to a subterranean zone (24). One or more articulated wells (16) extend from the entry well (12) to the subterranean zone (24). At least one of the articulated wells (16) intersects at least one of the one or more drainage wells (14) at a junction proximate the subterranean zone (24). A drainage pattern (32) is formed coupled to the junction and operable to conduct fluids from the subterranean zone (24) to the junction.
