Method and system for removing fluid from a subterranean zone using an enlarged cavity

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 (420, 520, 620, 220, 120) in the well bore (430, 530, 630, 230, 130) such that the enlarged cavity acts as a chamber to separate liquid from gas f...

description 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 (420, 520, 620, 220, 120) in the well bore (430, 530, 630, 230, 130) such that the enlarged cavity acts as a chamber to separate liquid from gas flowing from the subterranean zone (415, 515, 615, 215, 115) through the well bore. The method includes positioning a pump (444, 544, 644, 244, 144) 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.
