Sensorless Pump Off Control: the innovation that launched a company

Improving production while lowering lifting costs. That’s the ultimate goal that every oil and gas producer is aiming for. 

And that’s exactly what the Sensorless Pump Off Controller does. SPOC helps you pull more product from the ground while lowering your costs. It works on oil, gas and CBM gas wells; it’s even an improvement over wells with traditional pump off controllers.

Sensorless Pump Off Control

SPOC will work on beam pumps and progressive cavity pumps. The software resides in the SPOC Automation drive and requires no external sensors, wires, load cells or other field devices that fail over time.

SPOC uses technology that analyzes the motor’s rotor relationship to the stator to determine the load and position. As with traditional pump off controllers, pump off is determined when the load is reduced at specific positions.

With SPOC, you can establish high load limits and adjust intra-stroke speeds to maintain those limits. Unlike traditional pump off controllers, SPOC gives you text messages on the VFD keypad showing problems such as pump off, parted rod, leaking valve, high load and minimum load, even shutting down if conditions warrant. All this data is available via ModBus RTU as read and write values. SPOC allows you to monitor, control and fine-tune the drive/pump off controller at the well site or by using telemetry and SCADA systems.

Wiseguy™ Interface

The WiseGuy™ series of drive interface products is our latest innovation in drive technology. The days of needing a specialist around to change speeds, get the amps, production data, run time or other information you need from your drives are over.

WiseGuy can tell you everything you need to know about your well. And the touch screen technology and oilfield terminology make it simple to use. WiseGuy interface is the most user-friendly on the market.

Smart. Intuitive. Easy. These are the most common words customers use to describe the WiseGuy. If you know industry terminology like “SPM” (Strokes per Minute), “Pump Run Time” (“Real Time Run Time”), and “Number of Pump Offs,” you can program the drives. It’s really that easy.

Service is always a standard feature

Service is always a standard feature

The oilfield is a difficult, often brutal place, especially for rod pump applications. But we understand the pressure to keep your pumps running, no matter the conditions. Our drives are engineered and built to run through the extremes of heat and cold, through dust and dirt. That said, we realize that in the oilfield everything is susceptible to break, sooner or later.

If one of our drives goes down, our technical team is available 24/7.

We will have you back up and running in hours, not weeks. As one of our clients said: “In the oilfield, there is no tomorrow. Only today.”

That is the belief we live by.

We also offer DriveShield, the most comprehensive extended warranty in the entire industry. With DriveShield, you are protected at all times, even against lightning strikes.

Our low-harmonic drives keep you running reliably, efficiently and in compliance

Harmonic drive compliance becomes more critical every day. At SPOC, we focus on the entire system, providing low-harmonic drives to ensure that you continue running reliably, efficiently and in compliance of IEEE519 and EN-6100-3-2.

We manufacture every type of low-harmonics drive, using the latest technology available.  Everything we do is tailored to your needs.

In general, we recommend the Active Front-End VFD  for minimizing harmonics in fields incorporating variable speed drives. This technology is electronically based, not magnetically based. It meets the IEEE519 under every scenario and all loading conditions, regardless of voltage imbalance or source impedance. It is so advanced it can actually correct for low-voltage conditions from marginal systems and correct power factor within the electrical system, saving you money.
