摘要
In accordance with one embodiment of the present invention, a subterranean drainage pattern for accessing a subterranean zone includes a main well bore extending from a surface well bore, located at a first end of the area, to a second end of the area. A first plurality of lateral well bores extend in spaced apart relation to each other from the main well bore to the periphery of the area on a first side portion of the main well bore. A second plurality of lateral well bores extend in spaced apart relation to each other from the main well bore to a periphery of the area on a second, opposite side portion of the main well bore. A first plurality of ramping well bores extend in spaced apart relation to each other from the main well bore toward a boundary of the subterranean zone.
