Claims25
A method for accessing a first and a second subterranean zones from the surface, comprising:
- forming a first well bore extending into the first subterranean zone;
- forming a second well bore intersecting the first well bore at a junction proximate the first subterranean zone, at least a portion of the second well bore horizontally offset from the first well bore between the surface and the junction;
- forming a first drainage well bore coupled to the first well bore and extending into the first subterranean zone;
- and
- forming a second drainage well bore coupled to the first well bore and extending into the second subterranean zone.
