Key Energy Applies Advanced Industrial Control Algorithms with NI

12/18/2003 - National Instruments announced Key Energy Services Inc. (NYSE:KEG), a leader in onshore energy production services, has selected the new NI Compact FieldPoint analog I/O module for collecting oilfield data and performing embedded control on a fleet of oil well service rigs. The FP-AIO-600 and cFP-AIO-600 analog modules deliver a balance of four input and four output channels and an internal update rate of 1.7 kHz useful for LabVIEW Real-Time advanced industrial control applications.

Key Energy contracted Advanced Measurements Inc. (AMI), a National Instruments Select Integrator, to develop a control and measurement system for a fleet of oil well service rigs, which demanded accurate timing for running a closed-loop control algorithm. Because the cFP-AIO-600 delivers an improved internal update rate of 1.7 kHZ and a combination of I/O, Key Energy now can reduce instabilities causing jitter in control loops.

Using National Instruments LabVIEW Real-Time running on FieldPoint or Compact FieldPoint, Key Energy now can implement sophisticated control algorithms. "We chose Compact FieldPoint because it provided the necessary flexibility needed to implement PID, fuzzy logic and all types of control schemes," said Arden Albert, System Integrator for AMI.

Because these rigs operate in extreme temperature and vibration, Key Energy required a rugged, reliable control and monitoring system. "The ruggedness of Compact FieldPoint was a major factor when selecting the hardware for this system," Albert said. "We needed something that would handle high temperature, high vibrations, long operating hours, and run consistently for a long period of time."

About Compact FieldPoint
Industry analysts categorize Compact FieldPoint with a new line of products called programmable automation controllers (PACs) ( that combine the reliability and ruggedness of the PLC with the software functionality and flexibility of an industrial PC. Unlike PLCs, control and design engineers can use Compact FieldPoint and easy-to-use LabVIEW software to efficiently perform analog control and custom calculations. Using PACs, control and design engineers can perform analog and discrete control, user-defined data logging, Web-enabled applications and advanced control algorithms. Compact FieldPoint is ideal for high-vibration applications, withstanding 50 g of shock and 5 g of RMS vibration, even when mounted on heavy machinery or in vehicles. Compact FieldPoint operates in temperatures ranging from -25 C to 60 C, so users can run embedded LabVIEW applications in extreme environments where many industrial PCs fail.
