Abstract
Hydrocarbon wells including electrically actuated gas lift valve assemblies and methods of providing gas lift in a hydrocarbon well. The hydrocarbon wells include a wellbore that extends within a subterranean formation and downhole tubing that extends within the wellbore. The hydrocarbon wells also include a lift gas supply system configured to provide a lift gas stream to a lift gas supply conduit of the wellbore, a plurality of electrically actuated gas lift valve assemblies, a valve power supply system, and a controller. The methods include measuring a respective pressure differential between a lift gas supply conduit and a production conduit of the hydrocarbon well at each electrically actuated gas lift valve assembly in a plurality of electrically actuated gas lift valve assemblies of the hydrocarbon well. The methods also include selectively opening a selected electrically actuated gas lift valve assembly based on the respective pressure differential.
