Caterpillar Oil & Gas announces launch of gas blending solution

The 1 MW-rated DGB Gen 2 Kit aims to address the need for drillers to face the complexity of improving operational efficiency and reducing GHG emissions without compromising performance and uptime. Solutions that support climate-related targets and maintain efficiency without incurring significant additional costs are in demand.

Dual-fuel technologies like the DGB Gen 2 Kit represent a key strategy to address rising fuel costs, evolving industry regulations and the CAPEX associated with new gas engines. Optimised to blend diesel and natural gas, the DGB Gen 2 Kit features advanced cylinder technology that improves combustion efficiency. Its port injection system allows for precise air/gas ratio control at the individual cylinder level, resulting in faster response times while reducing unburned gas. Multi-port gas injectors and in-cylinder pressure/temperature systems enable real-time performance optimisation for each cylinder.

In addition to lowering GHG emissions, the DGB Gen 2 Kit allows up to two times diesel displacement compared to traditional fumigated technologies to achieve an average 70% diesel displacement, and up to 85% peak displacement. This significantly reduces overall fuel consumption and empowers companies to accurately estimate diesel fuel savings.

Drilling companies can upgrade all engines on a four-engine rig for nearly the same cost as one new gas-powered engine, which supports decreased capital expenses while also ensuring a diesel-like transient response. Additionally, reducing diesel consumption allows the DGB Gen 2 Kit to help lower operating expenses.

"With the DGB Gen 2 Kit, drilling companies can maximise their investments in Tier 2 engines while significantly reducing GHG emissions,” stated Derek Kamp, Vice President, Caterpillar Oil & Gas. “The ability to displace 70% of diesel consumption with natural gas without purchasing a new natural gas engine helps drilling companies optimise their existing assets and profitability."
