  • Method and apparatus for flowing fluid from a plurality of interconnected wells
    Patent number: 4243102
    Abstract: Method and apparatus for flowing fluid from a plurality of interconnected wells wherein a pressurized lift gas is injected into a well thereby actuating a pumping unit located in the well. Upon actuation, at least a portion of the partially expended lift gas is injected into an adjacent well whereby this adjacent well is pre-pressurized prior to it being fully pressurized by lift gas for actuation. This pre-pressurizing decreases the fully pressurized gas needed to actuate the second well.
