DrSCADA AutomationCalgary, Canada“More accurate and cost effective than just site visits and volume testing!” says savvy production tech with 20 years experience.“Any well worth pumping is worth the investment of a wellhead manager.” “Pumping wells without wellhead managers is simply barbaric!” says a Canadian production engineer who ran the same Alberta field before and afterinstallation of DrSCADA wellhead managers.
Solar-powered DrSCADA wellhead manager on a gas jack
We manufacture and support wellhead managers for beam pump optimization and simpler applications. Field service is provided by instrumentation & electrical firms near your oilfield, or your own technicians. Our goal is to help oil & gas companies monitor, control and operate their wells with greater business efficiency - to reduce risk & opcost, and increase net revenue.
DrSCADA is about to start field tests on a gas optimization product, as a team effort with one of our resellers, RTUIQ. The application will reduce shutin time for plunger lift installations, so that more time is spent in producing gas. A manual test of the process reduced the shutin time on an existing well by 2 hours per day. The economic value of this application is to produce more gas. With 2 hours more production per day, on the test well that was producing 16 e3m3 daily, that should be worth at least $8000 per month per well. Obviously there will be some variation from well to well. We will monitor the site operation over a cellular connection, and save data at high resolution. If you are interested in seeing this kind of improvement on your wells, reach us via the contact page.
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.
