Oil and Gas
Reliable, efficient, and low-emission power solutions for upstream and midstream oil and gas operations.
About the Oil and Gas Industry
The oil and gas industry operates in some of the world’s most challenging environments, where reliable and efficient energy supply is essential for continuous production. Remote wellheads, processing plants, and compression stations often lack access to stable grid power, requiring dependable onsite generation.
Gas engine power plants offer a robust solution by converting available gases—such as natural gas, associated petroleum gas (APG) also called “flare gas”, or coal seam gas (CSG)—into clean, reliable electricity and heat. These systems help operators improve energy efficiency, lower emissions, and reduce dependence on diesel fuel.
By capturing and using flare or waste gas for power generation, oil and gas producers can transform emissions liabilities into productive energy assets. This supports operational resilience, cost savings, and compliance with environmental and ESG commitments.
Gas engines can form the cornerstone of microgrids adding solar, battery energy storage systems or other technologies to improve the environmental performance and resilience of oil and gas power generation installations.
Benefits of Gas Engine Power for Oil and Gas
• Energy Resilience: Provides continuous onsite power for off-grid and remote facilities.
• Flare Gas Recovery: Converts waste or stranded gas into electricity, avoiding methane emissions.
• Cost Efficiency: Reduces diesel consumption and fuel transport costs.
• Emission Reduction: Cuts CO₂ and methane emissions through efficient combustion.
• Fuel Flexibility: Operates on natural gas, APG, CSG, or hydrogen blends.
• High Efficiency: CHP and heat recovery options achieve total efficiencies above 80%.
• Fast Deployment: Modular and skid-mounted systems minimise site installation time.
Energy Resilience
Reliable power is critical for oil and gas operations, where production downtime can result in significant economic loss. Gas engine-based power systems deliver stable, dispatchable energy even in remote or isolated regions. Capable of operating in island mode, these systems maintain uninterrupted power for critical loads such as pumps, compressors, and control systems.

Flare and Associated Gas Utilisation
Gas engines provide an effective method for converting waste gases—including APG and flare gas—into useful electricity and heat. This process eliminates flaring, reduces methane emissions, and transforms by-products into valuable onsite energy. Using stranded or waste gas as a fuel source reduces the need for diesel, improves environmental performance, and supports operators in meeting global methane-reduction initiatives.
Off-Grid and Island Mode Power
For remote sites without reliable grid access, gas engine systems operate independently in island mode, ensuring continuous power supply for drilling, extraction, and processing facilities. These units can be configured for automatic load control and parallel operation to match varying site demands. Modular and containerised designs enable fast mobilisation, making them ideal for temporary or rapidly deployed power solutions in remote field locations.
Fuel Flexibility and Modular Design
INNIO Jenbacher gas engines are designed to operate on a wide range of fuels including natural gas, APG, CSG, and hydrogen blends, making them suitable for upstream and midstream applications. Systems are available in modular or skid-mounted configurations for fast deployment and ease of transport. Their flexibility allows operators to expand or relocate capacity as production demands evolve, ensuring sustained energy security and long-term reliability.
Heat Recovery and CHP Integration
Where heat demand exists, gas engine systems can be configured for Combined Heat and Power (CHP), recovering waste heat from the engine’s exhaust and cooling circuits. This energy can be used for water or glycol heating, process steam, or absorption cooling, improving overall site efficiency. CHP reduces total fuel use and emissions, making it a cost-effective way to decarbonise energy-intensive operations.
Microgrids
Microgrids anchored in gas engine technology can play a pivotal role in supporting the oil and gas sector by delivering resilient, on-site power that ensures operational continuity in remote and energy-intensive environments. Gas engines provide a reliable and flexible generation source capable of running on natural gas or associated gas, turning what would otherwise be flared or wasted into valuable energy. This approach not only reduces emissions but also enhances energy efficiency by enabling combined heat and power (CHP) for process heating and facility needs. Furthermore, gas-engine-based microgrids can integrate with renewables and battery storage, creating hybrid systems that optimize fuel use, lower costs, and improve sustainability—critical for oil and gas operators seeking to decarbonize while maintaining high reliability in harsh conditions.
