  • Patent number: 10920546
    Abstract: An exemplary method of the present disclosure includes causing, by a processing system proximate to the wellbore, injection of the lift gas into the wellbore at a first gas injection rate; obtaining, by the processing system, a first indication of a parameter associated with the wellbore, an arrival of a first fluid at a wellhead associated with the wellbore, or a composition of the first fluid; determining, by the processing system and based on the first indication, at least one of: a second gas injection rate of the intermittent gas lift system, a first period to inject the lift gas with the intermittent gas lift system, or a second period, subsequent to the first period, with no injection of the lift gas by the intermittent gas lift system; and operating, by the processing system, the intermittent gas lift system according to the determination.
