Production of oil and gas in the oilfield can be a challenge when utility power is not available. The Caterpillar product line of oilfield gas generator sets provides the ideal solutions for this challenge. Engines are designed to run on low to no-cost well site gas without sacrifice on performance. These generator sets allow customers to significantly reduce fuel cost and avoid the expense and logistics of diesel fuel deliveries. Plus, they are designed to withstand the harsh conditions in the oilfield and feature a heavy-duty construction ideal for loading and unloading operations. Cat generator sets are backed by the worldwide network of Cat dealers ready to support your operation with technical support, service, parts, and warranty. CG137-12 oilfield gas generator set. Rating: 400 ekW (500 kVA) @ 60 Hz (1800 rpm). Configurations available to meet NSPS emission standards in non-attainment areas. Product Design
