2.1 Phases and Control Modes
The most basic form of a plunger lift cycle has three phases.
Tubing On: The phase of the cycle in which the tubing (or sales) valve is
opened and the plunger begins moving toward the surface.
Afterflow: The phase of the cycle in which the tubing valve remains open
after the plunger has arrived and offloaded its fluid.
Tubing Off: The phase of the cycle in which the tubing valve is closed to
allow the plunger to return to the bottom of the well.
The ACiC offers you 3 mode selections for well operations:
Plunger Arrival
To operate with a single motor valve on the flow line, select the Plunger
mode.
Figure 2.1: Depiction of Auto-Cycle Phases
To operate with dual motor valves, perhaps one on the flow line and one redirecting flow to the stock tank, select Tank
mode.
Tubing
On
Both Plunger and Tank modes allow you to make time adjustments to the Off
Time and Afterflow.
Tubing Off
To operate with a single motor valve on the flow line and not make any automatic adjustments to the operation select
Timer mode.
Timer mode has a reduced number of operating parameters (Tubing On, Tubing
Off and High-Line Delay) and is available strictly for simplicity of intermittent
operation.
