Oil and gas exploration and production operations run around the clock in some of the most remote, demanding environments on earth. From drilling rigs and offshore platforms to pipeline compression stations and processing facilities, uninterrupted power is not optional, it is the prerequisite for every operation. Downtime is measured in lost production, and the consequences of an unreliable power source extend well beyond the generator room.
Depco Power Systems supplies diesel generators, natural gas generators, gensets, and industrial engines for oilfield drilling and E&P operations worldwide. Our inventory includes new, used, and low-hour units from Caterpillar and Cummins, two of the most widely specified brands in oil and gas power, available for immediate shipment or scheduled delivery.

Power Generation Systems for Oil and Gas Operations
Oilfield power requirements vary widely by application. Drilling rigs require high-capacity generator sets to drive the rotary table, mud pumps, and draw works. Wellsite operations need reliable standby and prime power for instrumentation, lighting, and pumping systems. Processing and compression facilities demand continuous-rated generation for variable loads across multiple systems. Depco supplies the full range:
Diesel Generators for Oilfield and Drilling Applications
Diesel generator sets are the primary power source for drilling rigs, wellsite facilities, and remote oilfield operations. They offer the fuel flexibility, durability, and low-maintenance profile required for continuous-duty use in locations far from utility infrastructure.
- Common generator sizes for drilling operations: 250 kW to 2,000+ kW depending on rig class and load requirements
- Caterpillar C15, C18, C32, and 3512 series, widely specified for drilling and production power applications
- Cummins QSK, QST, and KTA series, proven in oilfield generator sets globally
- Weatherproof and open-frame configurations for permanent installations and portable wellsite deployments
- Generator ends available separately for genset rebuilds
Natural Gas Generators for Oil and Gas
Where pipeline natural gas or wellhead gas is available, natural gas generator sets offer a fuel-cost advantage for base load and continuous-duty power applications. They are common in processing plants, compression stations, and mature production fields with established gas infrastructure.
- Natural gas gensets from Caterpillar (G3500, G3600 series) and Cummins for oilfield power applications
- Wellhead gas-fueled configurations for operations with associated gas flaring reduction targets
- Dual-fuel options available for sites with variable gas quality or supply interruptions
Oilfield Generator Sets (Gensets)
Complete generator sets (engine, alternator, and skid, configured for oilfield deployment) are available from Depco's inventory in new-surplus, low-hour, and quality-used condition. Oilfield gensets are typically configured for prime power or continuous-rated duty, with fuel tanks, control panels, and weatherproof enclosures matched to site requirements.
- Open and enclosed genset configurations for wellsite and production facility applications
- Single-unit and multi-unit parallel configurations for larger load requirements
- Skid-mounted and trailer-mounted options for portable oilfield deployment
Industrial Engines for Drilling Rigs
Well servicing engines and industrial engines power the mechanical systems at the heart of any drilling operation: drawworks, mud pumps, and rotary tables. Engine selection is critical to rig performance and operating cost.
- Caterpillar and Cummins diesel engines for drilling rig mechanical drive applications
- High-output engines rated for continuous heavy-duty oilfield cycle
- New, remanufactured, and low-hour used units, often at significant savings versus new OEM pricing

FAQ: Power Generation Systems for Oil and Gas Operations
What type of generators are used in oil and gas operations?
Oil and gas operations primarily use industrial diesel generator sets for prime and continuous-duty power. Diesel gensets are preferred for drilling rigs and wellsite facilities due to their fuel storage flexibility, durability in remote locations, and low dependence on utility infrastructure. Generator sizes range from 250 kW for smaller wellsite operations to 1,000 kW or more for large drilling rigs, where multiple units are often run in parallel to meet total load requirements. Where pipeline natural gas is available, natural gas gensets are used for base load power at processing and compression facilities. Caterpillar and Cummins are the most widely specified brands for oilfield generator sets.
What is the difference between a generator and a genset in oilfield applications?
A generator (or generator end / alternator) converts mechanical energy into electrical power. A genset (generator set) is the complete packaged unit: an engine driving a generator end, mounted on a common skid with fuel, cooling, and control systems. In oilfield procurement, 'genset' typically refers to a ready-to-deploy package, while 'generator' may refer to the alternator end only. Depco supplies both complete generator sets for immediate deployment and generator ends separately for customers rebuilding or repairing existing units.
What generators are used on drilling rigs?
Drilling rigs use high-capacity diesel generator sets to power the rig's electrical systems: the top drive or rotary table, draw works, mud pumps, lighting, and onboard instrumentation. Most modern drilling rigs run multiple generator sets in a paralleled configuration to meet variable load demands and provide redundancy. Common specifications include Caterpillar C32 and 3512-series generator sets and Cummins QSK-series units. Total rig power requirements range from 1,000 kW for smaller land rigs to 5,000 kW or more for large offshore drilling platforms.
Does Depco supply oilfield generators internationally?
Yes. Depco ships generator sets, gensets, and industrial engines to oilfield operations internationally, including customers in Latin America, Southeast Asia, the Middle East, and Africa. Our inventory of quality used and low-hour Caterpillar and Cummins generator sets provides a cost-effective solution for E&P operators looking to equip or expand field operations without the lead times and cost of new OEM equipment. Contact our sales team to discuss availability, specifications, and international shipping options.
What is the difference between prime power and standby generators for oil and gas?
Prime power generators are designed for continuous-duty operation as the primary power source, the standard requirement for remote oilfield and drilling locations with no grid connection. Standby generators are rated for intermittent use as backup to a primary utility feed. For most oil and gas applications in remote or offshore locations, prime-rated or continuous-rated generator sets are required. Depco's sales team can help identify the correct power rating for your specific application and load profile.
