Question · Q3 2025
Dan Kutz asked for an update on the size of the Emerald fleet (100% natural gas-powered equipment) after the latest direct-drive delivery. He also requested a juxtaposition of the differences between Emerald electric fleets and direct-drive fleets in terms of build cost, maintenance cost, fuel/operating cost, and operating efficiencies.
Answer
Andy Hendricks, President and CEO, stated the Emerald fleet is 'around that 250,000 level right now,' with more 100% natural gas direct-drive units being delivered and deployed this quarter. He noted that overall horsepower has decreased from 3.3 million to 2.8 million, which he views constructively for the completions market, and will provide an updated exact number on the next call. Mr. Hendricks explained that Emerald electric performs well but requires significant capital for turbines (e.g., $40M-$45M for a 35MW turbine). The new 100% natural gas direct-drive engines (3,600 HP) offer a '25%, maybe 30% reduction' in overall capital cost for the same horsepower at location compared to electric with turbines. While direct-drive OpEx is higher than diesel, it's projected lower than maintaining electric pumps and turbines.
