A process for aging gas lift valves utilizing a controlled decompression to prevent damage to seals of the gas lift valves. The process includes pressuring one or more gas lift valves to a predetermined pressure (e.g., 5000 psig) and maintaining this pressure for a predetermined time (e.g. five minutes). After this time period, decompression is performed in discrete steps. For instance, the pressure of the pressure vessel may be reduced in predetermined pressure increments (i.e. reductions). After each pressure reduction, the reduced pressure is maintained for a predetermined time. This allows gasses and fluids within the elastomeric O-rings time to dissipate without causing damage to the seals.

Gas lift valve aging process and apparatus

A chemical/additive injection controller, system and method (i.e., utilities) are provided that control when an injection pump turns on and off in order to inject a predetermined volume of additives into a hydrocarbon production conduit over a predetermined number of cycles per day. The controller determines when to activate and deactivate (i.e., turn on and turn off) an injection pump to provide a desired total additive injection volume over an injection period (e.g. 24 hours). More specifically, the utilities incorporate a flow meter that monitors the actual amount of additive that is injected during a pump cycle. Once an injected volume meets or exceeds a target injection volume the pump is deactivated. The flow meter continues to monitor the injection volume including amounts injected after power to the pump is deactivated to provide an accurate measure of the total injection. Subsequent injections are varied based on the actual measured volume of one or more previous injections.
