<p>A system for enhanced access to subterranean zone from the surface includes a well bore pattern (100) having a first well bore (104) extending from a surface well bore substantially defining a first end of the area in the subterranean zone to a distant end of the area. The pattern also includes a plurality of lateral well bores (110) extending outwardly from the first wel l bore. The distance from an end of a lateral well bore to the surface well bo re may be configured to be substantially equal for each of the lateral well bor es to facilitate forming the lateral well bores. The system and method may also include nesting two or more well bore patterns within the subterranean zone to provide uniform coverage of the zone. Additionally, the system and method ma y include multiple well bore patterns in communication within common surface well bore to reduce the surface area required for accessing the subterranean zone.</p> |
