发明名称 Wellbore Pressure Actuation of Downhole Valves
摘要 Methods and systems for operating a valve control system to control a valve in a wellbore include identifying a differential pressure arrangement of a plurality of differential pressure arrangements for actuating the valve to a desired state based on a differential pressure of at least two pressure sources of the wellbore and a present state of the valve. Once identified, the differential pressure arrangement of the at least two pressure sources are utilized to initiate actuation of the valve from the present state to the desired state.
