Applicants have created systems, methods, and apparatuses for increasing the production of fluid from a subterranean well. The system can include a controller and upper and lower portions. The upper portion can include an injection valve for regulating the amount of a first gas injected into an injection conduit. The lower portion can include a chamber valve for regulating the flow of a second gas through an upper tubing string and a vent valve for regulating the flow of the first gas and a standing valve. The collected fluid creates pressure in the lower portion causing the second gas to flow from the lower tubing string to the upper tubing string. The controller controls the injection valve and is coupled to a pressure gauge for measuring pressure in the lower portion. With the aid of this system, well operators can increase production of subterranean well formations, such as gas wells, without increasing backpressure on those formations.

To operate a device for use in a well, a counter mechanism is provided that is actuatable by pressure cycles to an active position that allows actuation of the device to a target state. A position retention mechanism is coupled to the counter mechanism to maintain the counter mechanism in the active position once the counter mechanism has been incremented by the pressure cycles to the active position.
