Abstract
A method for removing fluid from a subterranean zone includes drilling a well bore from a surface to the subterranean zone and forming an enlarged cavity in the well bore such that the enlarged cavity acts as a chamber to separate liquid from gas flowing from the subterranean zone through the well bore. The method includes positioning a pump inlet within the enlarged cavity and operating a pumping unit to produce the liquid through the pump inlet. The well bore may comprise an articulated well bore.
