ABSTRACT:
An improved method for making a well for removing fluid from a desired subterranean formation. This invention provides for a method for making a well for removing fluid from a desired subterranean formation having an interface zone. The interface zone is coupled to a main directional well bore that extends from a top surface at ground level into the desired subterranean formation. A lateral well bore is also coupled to the interface zone. A directional sump bore is also coupled to the interface zone and the directional sump bore extends from the interface zone to a point below the interface zone. There is also a means for moving fluid from the directional sump bore through the main directional well bore to the top surface.
