Well Service Engines

Oil and gas producers have relied on Caterpillar since the industry's earliest days. For 60 years, we've powered the petroleum business on land. Now we go with it onto the ocean, hundred of miles out, thousands of feet down.

3512E Tier 4 Final Well Service Engine

Well stimulation operations in the oilfield are complex and demanding. The 3512E Tier 4 Final engine for well service operations was specifically developed to meet Tier 4 Final emissions and to meet the highest standards in performance, durability, and reliability. Cat engines are backed by the worldwide network of Cat dealers ready to support your operation with technical support, service, parts, and warranty. 3512E engines, with ratings: 1678-1864 bkW (2250-2500 bhp) @ 1900 rpm meet U.S. EPA Non-road Mobile Tier 4 final emission standards.
