发明名称 WELL SYSTEM AND METHOD FOR CONTROLLING THE PRODUCTION OF FLUIDS
摘要 Embodiments of the present invention allow the placement of a stand alone device (valve) along a flow path, without a physical connection to the surface or reliance on the borehole for signaling, to provide a means to control the flow between reservoirs. This is achieved using a valve located in the flow path that can be actuated without sending signals down the borehole or well path and thereby eliminating the need for complicated signal lines and or fluid columns to actuate the valve.
