HOUSTON, Tex. -- With diesel prices remaining high, Antero Resources and Patterson-UTI Drilling were seeking a viable option to reduce fuel costs, a major expense when operating drilling rigs. That’s when the companies considered an innovative solution: the Waukesha VHP L7044GSI. Offered by GE’s Waukesha gas engines and Waukesha-Pearce Industries, the rich-burn engine is 100 per cent natural-gas-fired, reducing fuel costs while also meeting stringent state and federal mobile emissions guidelines.
