The Benefits Add Up With the Cat® Dynamic Gas Blending™ Engine
In the evolving oil and gas industry, oilfield companies need innovative solutions that reduce costs, optimize efficiency and support climate-related objectives. Leveraging fuel flexibility addresses each of those goals by helping oilfield companies choose the most advantageous fuel mix based on site conditions and other factors. That’s how the Cat 3512E Tier 4 Dynamic Gas Blending engine can provide a range of benefits in the field, and the numbers don’t lie.
Industry-Leading Diesel Displacement Percentage
The innovative 3512E Tier 4 DGB was the first dual-fuel engine to meet the U.S. EPA Tier 4 emission standard. With dual-fuel capabilities and in-cylinder pressure sensing (ICPS) technology that individually monitors cylinder pressure, it automatically controls combustion and adjusts gas flow to maximize diesel displacement.1 It also offers the widest fuel flexibility in the industry with the option to operate on compressed natural gas (CNG), liquefied natural gas (LNG), pipeline gas and field gas.2 This broad fuel flexibility allows oilfield companies to maximize their fuel blend based on the availability and quality of their fuel.
The Tier 4 DGB engine offers the highest diesel displacement rate in the industry to date, with an average of 65% diesel displacement and up to 85% peak diesel displacement under certain conditions. This supports lower fuel costs and decreased diesel use without compromising power or performance. In 2023 alone, pressure pumping companies reduced their diesel use by up to 100 million gallons by using T4 DGB solutions.3 Lab data also indicates that each 18-unit fleet can save 3.8 million gallons of diesel per year, adding up to significant savings.4
Award-Winning, GHG Emissions-Lowering Technology
The advancements of the 3512E T4 DGB engine that enable its high diesel displacement rate also help reduce GHG emissions. In addition to the ICPS system, the solenoid-operated gas admission valves work with the engine’s electronic control module to adjust fuel injection and admit an optimal amount of gas into each cylinder.5 That precise control of fuel flow maximizes fuel efficiency and lowers GHG emissions.
These and other innovations helped the 3512E T4 DGB engine win the U.S. EPA 2020 Clean Air Excellence Award in the Clean Air Technology category. In addition to attaining up to 85% diesel displacement and saving hundreds of millions of gallons of diesel annually, the engine has the potential to reduce flaring emissions by 58%, lower greenhouse gas emissions from flaring and tailpipe by 45%*, and decrease diesel truck traffic by 18 million miles annually.6 [Note to reviewers: Joshua Morrison to confirm stats.]
Remarkable Reliability that Powers the Future of Oil and Gas Operations
The adaptable T4 DGB solutions can run on any jobsite to deliver the performance and reliability oilfield companies’ demand while promoting a lower total cost of ownership (TCO) and supporting a dependable return on invested capital. For these reasons, this dual-fuel technology is a popular choice across the industry.
DGB solutions match the characteristics of their diesel counterparts, which gives oilfield companies confidence in the field. For example, the 3512E T4 DGB performance is identical to the Cat 3512E diesel engine, delivering the same power ratings, transient response and robust performance the industry requires. With field-proven durability, the 3512E T4 DGB solution has surpassed 14 million hours of operation to date across the major oil and gas basins7 in North America.
The award-winning 3512E Tier 4 DGB exemplifies the innovative solutions powering the energy industry’s future. Its impressive diesel displacement and fuel flexibility help oilfield companies improve operational efficiency while meeting evolving requirements.
