For decades, diesel was the king of the oilfield. It powered everything from drilling rigs to frac fleets to backup generators. It’s reliable, rugged, and familiar. But times have changed. What was once seen as the default fuel of the industry is quickly becoming its biggest liability.
Why? Well, the oil and gas sector is facing pressure from all sides.
Fuel costs are volatile and rising. Hauling diesel to remote locations isn’t just expensive—it’s inefficient. Every mile a fuel truck travels is a mile of cost, risk, and carbon emissions. And with the Permian Basin and other producing regions expanding deeper into remote areas, the logistics headaches only multiply.
Regulations are tightening. From federal emissions rules to ESG commitments made by public operators, the tolerance for dirty fuels is shrinking. Diesel’s high emissions profile—particularly its NOx and particulate output—makes it harder for producers to meet sustainability goals and stay in compliance.
Downtime isn’t an option. Power isn’t just about energy—it’s about uptime. And relying on diesel means depending on delivery schedules, mechanical reliability, and storage limitations. One delay in fuel supply, one breakdown in a generator, and an entire site can go offline.
All of this is forcing operators to rethink the fundamentals. If diesel is dragging operations down, what’s the alternative?
The Rise of Natural Gas Power in Oilfield Operations
Enter natural gas. Not new, but newly relevant. Many production sites already flare or vent excess natural gas—a byproduct of drilling that, until recently, was considered waste. But smart operators are flipping the script: instead of burning gas off into the sky, they’re capturing it and using it as a power source.
Natural gas is abundant, cost-effective, and significantly cleaner than diesel. Compared to diesel generators, natural gas turbines produce up to 50% fewer carbon emissions and drastically reduce harmful particulates. And if that gas is coming directly from the wellhead? Even better. That’s on-site, closed-loop efficiency with no hauling required.
This shift isn’t driven by sustainability alone. Operators are also motivated by the need for fuel stability, cost control, and operational reliability.
Major producers are now investing in on-site power generation systems, especially mobile and modular microgrids that use turbines or reciprocating engines to deliver scalable power exactly where it’s needed. While mobile systems offer rapid deployment and flexibility, modular microgrids provide a stationary, high-capacity solution designed to integrate seamlessly with long-term infrastructure plans. Together, they allow operators to adapt to evolving site requirements while maintaining performance, safety, and efficiency.
Goodbye, Diesel. Hello, Future.
It’s no longer a question of if diesel will be phased out—it’s a question of when. As the industry looks ahead to longer lateral lengths, bigger frac spreads, and increasing digitalization, power demands will only grow. And diesel simply doesn’t scale in a way that makes long-term sense. Natural gas is emerging as the preferred standard for forward-thinking operators ready to modernize how they power the patch.
PROPWR is proud to support that transition. We specialize in natural gas-powered mobile and modular microgrids for oilfield and industrial use. Our future-forward packages are engineered to meet a wide range of site demands, whether mobile or modular. Our systems convert in-field gas into reliable power, cutting emissions, costs, and delays.
