Product Design

- Robust design provides prolonged life and lower owning and operating costs- Designed for maximum performance on low pressure pipeline natural gas• One electronic control module handles all engine functions: ignition, governing, air fuel ratio control, and engine protection- Gas engines can be configured to run from many gases directly from the field. Some gas, depending on quality, may need to be treated prior to being injected into the cylinder. Using the locally sourced natural gas reduces fuel transport costs as well as site traffic and dust normally associated with the transportation of diesel fuel to drilling sites. - Fuel costs contribute a significant portion of the charges incurred over the life of the engine.- Using a gas engine instead of a diesel can greatly lower the overall cost of operation.

Committed to Sustainable Development

- Gas engines can be placed in most areas with little or no aftertreatment and reach very low emission levels- Meets most worldwide emissions requirements down to 0.5 g/bhp-hr NOx level without aftertreatment.


- Proven reliability and durability- Rugged engine, generators, radiator, and bases are a result of years of experience in the oilfield- Assembled, tested, and validated as a package to minimize vibration and maximize component life- Generator designed to accommodate the rigors of oilfield applications– Cat® SR4B generator is designed to match performance and output characteristics of Cat engines– Two-bearing, anti-friction, close coupled design to provide additional robustness against alignment issues– Insulation system provides virtually twice the instantaneous surge withstand capacity by using Mica turn taped magnet wire instead of glass covered magnet wire– Three-point mounting system provides protection to the generator set's driveline and alignment
