A Canadian production engineer ran the same Alberta field before and afterinstallation of DrSCADA wellhead managers. His comments?“Any well worth pumping is worth the investment of a wellhead manager.” “Pumping wells without wellhead managers is simply barbaric!”

DrSCADA wellhead manager with VFD driving 640 pumpjack.
A DrSCADA wellhead manager can protectyour rod string withshutdowns for high andlow loads. The same shutdowns can protect the gearbox and the structure from excessive loading.It can also detectand avoid fluid or gaspound, and duty cycle asingle speed pumpjack to run with a full pump, or can give speed control to a VFD to pump faster or slower as may be required. It can also monitor shutdown devices, like pressure switches, stuffing box leak detectors, and H2S sensors, and monitor multiple analog pressures. It can also manage a pressure PID loop to avoid excessive flowline pressure. What else would you like?

Here is a dynamometer plot…. and here are three screen shots of the video clip…
I did not publish the THUNK when the cables go loose, but it is certainly there in the audio! I think you might call that obstruction downhole!! This is a classic case of where a low area fault is a good shutdown to make use of, and why it should not be restartable except by an operator.
Cell phone texting might not give the highest graphics resolution available, but you sure get the required message quick!
