**Expert Model Only
The ALiEn2 Plunger Lift Controller Simulator is built off of the same software that is running on the controller. Use it for training, demonstrations, troubleshooting and more. Conveniently switch between the available models of the ALiEn2 and see a dynamic view of the available devices and menu items. The inside door instruction label, quick start guide, user’s manual, and Modbus guide are all conveniently built in so you have everything in one place.
This patented* algorithm reduces the need for operator intervention by making automatic adjustments that are proportional to the current flow/close time. When Adaptive Seeking Velocity Optimization™ is used with a plunger arrival sensor such as Cyclops, ALiEn2 reacts to the average velocity of the plunger, making proportionate changes to the amount of Close and Afterflow time for the well. The user specifies a Target Rise Velocity, which ALiEn2 then works to achieve. For best results, use a Sasquatch Plunger Velocity Sensor in conjunction with Adaptive Seeking Velocity Optimization™ to maximize production using real time Surface Velocity. ALiEn2 is the first plunger lift controller capable of optimizing on Surface Velocity; a standard feature in the ALiEn2 Expert model, available as an upgrade for the ALiEn2.
Use a combination of Line Pressure, Tubing Pressure, Casing Pressure** and Differential Pressure** to optimize the well. ALiEn2 automatically adapts to use enabled devices. Optimize on Flow Rate (AGA 3 table based) when using a Line Pressure and Differential Pressure sensor.
Load Factor is a parameter that can be used to determine when to open a plunger lift well to rise the plunger. It is a ratio of the slug size (casing pressure – tubing pressure) to the lifting pressure (casing pressure – line pressure). It is used by a number of different control systems as a standard optimization setting and is a standard feature on the ALiEn² Expert plunger lift controller. Please note that this feature requires a pressure splitter.

**Expert model.
The ALiEn2 plunger controller replaced a competitive controller on a plunger lift well that was not meeting production expectations. Production was doubled within 12 days and the well has continued producing at the higher rate since.
The Cyclops sensor was installed on wells that were frequently missing plunger arrivals, leading to 100% reliable detection of the plunger.
