SPOC Automation's SPOC is unlike any other Pump Off Controller…

SBP drives with SPOC controls Beam Pumps, Progressive Cavity Pumps and Electric Submersible Pumps!

The Sensorless Pump Off Controller (SPOC) from SPOC Automation is an innovative, industry-changing product that can improve production and lower operating costs of Oil and CBM gas wells, even over wells with traditional pump off controllers.

SPOC software resides in the SPOC Automation SBP drive and requires no external sensors, wires, load cells or other field devices. SPOC uses patented technology that analyzes the motor's rotor relationship to the stator to determine the load and position. As with traditional pump off controllers, when the load is reduced at specific positions pump off is determined.

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 drive keypad of 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.

Increased Production

• SPOC varies the strokes-per-minute (Beam Pumps) or speed (PCP & ESP's) to match the wells productivity. Eliminating down time reduces pressure on the reservoir, allowing more flow into the well.
  
  
• In Heavy Oil, SPOC automatically varies the strokes to reduce rod float and increases up stroke to maximize production.
  
  
• SPOC increases strokes-per-minute to compensate for well productivity
  
  
• One SBP Drive with SPOC will work on three applications, Beam Pumps, PC Pumps and ESP's.

Lower Energy Consumption

• Traditional pump off controller's run at a higher speed and then shut down; SPOC varies the speed within each stroke to reduce mechanical stress and cut electrical consumption.
  
  
• SPOC can reduce energy consumption on average, by 10-15 percent over traditional pump off controllers.
  
  
• SBP drives with SPOC have reduced energy consumption by 30-35 percent over wells without pump off controllers.
  
  
• SBP drives with SPOC reduce peak demand charges. Because SPOC varies its strokes or speed to match production, eliminating the need to shut down, it reduces the drives overall speed. The SBP drive package with SPOC can slow the motor to preset minimum speeds or the customer can choose to shut the unit down. Speed reduction, combined with overall efficiency gains, has reduced the demand for energy.

Lower Capital Cost

• SPOC can be installed in less than 25 percent of the time needed for traditional pump off controllers.
  
  
• SPOC requires NO External Sensors (Load Cells, Prox Switches, etc.) that fail over time.
  
  
• SPOC increases the entire system's efficiency, so when our engineers review your application, in many cases we can reduce motor, cable and transformer size.
  
  
• SBP drive with SPOC will replace the standard pump panel and requires no additional field sensors or equipment.

Fewer Mechanical Failures

• SPOC decreases speed during peak mechanical loads in each stroke (on beam pumps) by as much as 50 percent.
  
  
• Since the pump runs at an overall slower speed, it suffers less wear and fatigue over time.
  
  
• SPOC does not shut down during pump off, but rather slows down; this prevents sand, iron sulfide, etc. from falling back onto the plunger.

SPOC Automation gives you far more for far less than traditional pump off controllers…

• SBP drives with SPOC can significantly increase production from each well.
  
  
• SPOC reduces your energy usage and cost by up to 35 percent.
  
  
• Because it has no external sensors, hardware or load cells, it is far more reliable.
  
  
• SPOC reduces mechanical down time and repair cost.
  
  
• When a problem occurs in the well, you typically know the exact nature of the problem and the solution – sooner.
