Control Techniques’ AC drive solutions provide reliable and efficient motor control for drilling and artificial lift pumping applications

With around 25 years of experience and engineering expertise in the global oil extraction industry, Control Techniques' highly reliable, high performance and efficient drives allow us to develop solutions that can maximize production and extend the operational life of oil wells. Our innovative technology systems are tailored to the exact requirements of well conditions; our smart drive controls, protects & monitors pumps parameters while maintaining system integrity.

Scalable and localized well management solutions and services

We can provide anything from a single drive for local integration, to a fully engineered variable speed drive (VSD) surface package (drive, cabinet, monitoring and step-up transformer if required), providing the benefits of energy efficiency and flexible process control for Electrical Submersible Pump (ESP), Reciprocating Rod Pump (RRP) and Progressive Cavity Pump (PCP) applications.

Our solutions incorporate dedicated artificial lift functionality that reduces equipment wear and down-time, while improving well productivity and system longevity:

• Real-time monitoring and regulation of the load level due to changing well conditions reducing equipment wear and down-time, while extending system life;
• Back-spin protection;
• Pump release ‘rocking start’ mode.

Flexible and customizable systems to meet the challenges of oil well production

Our flexible VSD modules are based on a Modular concept and provide:

• Indoor or outdoor installations through adaptable enclosures and footprint when installed offshore;
• Easy maintenance as individual modules are easily and quickly replaced on site;
• Conformance with standards, such as IEEE 519 and ATEX certification where required;
• Capability to power AC and permanent magnet motors, as well as ESP & Beam pumps;
• Air and liquid-cooled modules for harsh environments and reduced cabinet size.

Easy user interface and system monitoring to optimize performance

• Fieldbus communications that easily integrate with field systems;
• Intuitive HMIs for commissioning or operational changes;
• Accurate data monitoring and logging with local and remote displays;
• Remote control to minimize costly site visits.

Protecting system integrity

With our long experience of harmonic mitigation, we provide comprehensive 6, 12, 18, 24 pulse and Active Front End (AFE) solutions. AFE technology reduces harmonic distortion to the mains supply to typically 3.5% or less.

Due to large cable lengths of ESPs, the variable AC (current, voltage & frequency) waveform passes through the sinewave filtering system, delivering perfect and optimum torque and pump performances.
