International Classification:

E21B 43/12
E21B 47/06
E21B 47/04
E21B 41/00

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.

Abstract:

Methods and apparatus are provided for measuring one or more parameters associated with an artificial lift system for hydrocarbon production and operating the system based on the measured parameters. One embodiment of the invention provides a lubricator for a plunger lift system, which generally includes a housing, a spring disposed in the housing for absorbing an impact by a plunger, and a sensor configured to measure at least one parameter of the spring. One example method of operating a plunger lift system for hydrocarbon production generally includes measuring at least one parameter of a spring disposed in a lubricator of the plunger lift system and operating the plunger lift system based on the measured parameter.
