GreenMan Technologies’ Subsidiary Commissions Dual Fuel Technology to Power Cimarex Energy Drilling Rig Site (USA)

GreenMan Technologies, Inc. announced that its American Power Group, Inc. subsidiary (APG) has converted and commissioned three Caterpillar 3512 diesel powered generators to run on a combination of pipeline natural gas and diesel fuel at a Cimarex Energy Co. (Cimarex) Mid-Continent drilling site.

APG utilized its new third generation S3000 Series Dual Fuel System which relies on its read-only CAN-bus Turbocharged Natural Gas ™ technology to seamlessly meter and control the dual fuel within all original OEM diesel engine performance parameters. During commissioning the generators achieved an average 50% displacement in diesel fuel, creating a significant fuel cost reduction as well as decreased emissions. The order was booked and managed through Cactus Drilling Company LLC (Cactus).

APG’s dual fuel system converts diesel engines and diesel generators to function more efficiently and at a lower operating cost (average net fuel cost savings of 20% – 35%) by seamlessly displacing up to 40%-60% of the normal diesel fuel consumption with either CNG, LNG, pipeline gas, well-head gas, or other qualified bio-methane gases. APG’s system is non-invasive to the OEM engine and operates within all OEM performance controls with the flexibility to return to 100% diesel operation at any time. APG’s dual fuel conversion and emissions reduction systems can help users achieve their sustainability goals through lower carbon monoxide, nitrogen oxide, and particulate matter emissions. In addition, the introduction of natural gas through APG’s dual fuel system does not impact diesel engine power or torque and will assist in extending the engine’s oil life as natural gas is a cleaner burning fuel compared to diesel.

Lyle Jensen, GreenMan’s President and Chief Executive Officer stated, “We are pleased to have worked with the Cimarex and Cactus field operations personnel on this initial conversion which was completed while the drilling rig was in full operation and was completed with minimal on-site work. The results have exceeded GreenMan’s initial expectations and we look forward to additional opportunities to demonstrate how dramatically our dual fuel solution can positively impact the bottom line for oil and gas drillers.”
