For contractors who prefer to enter the dual-fuel market with built-in technology rather than retrofits, China-based Honghua Group and its US subsidiary Honghua America are developing a next-generation onshore rig for shale drilling that will come equipped with dual-fuel engines.
A prototype for the rig is under construction at the company’s Houston yard and scheduled for completion in late 2013 or early 2014.
“Dual-fuel engines, or more specifically mixed-fuel engines, have been maturing in the European and United States markets for the past 15 years and is only now more widely used, not only in applications of power rigs but also fracturing engines,” Zhang Mi, chairman and president of Honghua Group, said.
In China, too, he sees a growing prevalence in dual fuel, particularly for unconventional oil and gas exploration. “The trend of dual-fuel systems being adopted throughout North America and other countries is already quite noticeable, but in China a few companies, such as PetroChina Xinjiang Oilfield, have also begun pilot programs. Future demand will be quite large, especially in America, as companies are beginning to develop processes to purify the unpurified gas that is expelled from wells.” Better processes for conditioning field gas will expand dual-fuel applications for the future, he said.

The rig, which is scheduled for completion late this year or early next year, will come equipped with dual-fuel engines.
