Cummins announces dual fuel engine for land-based drilling
ODESSA, Texas -- Cummins Inc. (NYSE: CMI) announced today its plans to produce Cummins Dual Fuel (TM) engines for land-based oil and gas drilling applications using Cummins Dual Fuel technology. The first engine for land-based drilling applications is the Tier 2 QSK50, rated at 1480 hp at 1200 rpm. Other QSK Series engines will follow, including engines capable of meeting upcoming U.S. Environmental Protection Agency (EPA) Tier 4 Final emissions regulations.
The Cummins Dual Fuel QSK50 will operate with integrated controls that will optimize the substitution rate based on operating conditions, and will seamlessly and automatically transition between diesel fuel and dual fuel modes. Cummins Dual Fuel technology enables drilling equipment to operate on 100 percent diesel fuel or in dual fuel mode, giving the customer flexibility depending on natural gas availability at the drilling site.
"Since our announcement of well-servicing dual fuel engines in April, customers around the world have voiced strong interest for Cummins Dual Fuel engines, specifically customers running land-based drilling applications," said Mark Levett, Vice President - High-Horsepower Engine Business.
"Cummins is committed to delivering products that meet our oil and gas customers' needs while at the same time lowering their operating costs. Land-based drilling rig operators run long, tough hours over the course of a year, consuming large amounts of fuel. Customers can expect to see significant fuel savings, and will see a return on capital investment in less than one year of operation," Levett added.
In dual fuel mode, the substitution rate, which is the percentage of natural gas relative to total fuel flow, is the critical parameter affecting fuel savings. In traditional operating conditions, engines with Cummins Dual Fuel technology can be expected to deliver a maximum substitution rate of 70 percent.
The Cummins dual fuel solution will be applicable to both new QSK50 engines and as a retrofit on existing QSK50 engines. Cummins global distribution network will handle upfit, commissioning and warranty on dual fuel solution engines.
Dual fuel Drilling Power Modules will be available through the Cummins Oil and Gas Center of Excellence in Houston at launch. Additional details on the solution and product introduction timeline will be shared in the coming months.
