Gas turbines play a crucial role in the oil and gas industry, providing the power needed to drive high-horsepower equipment and respond quickly to operational demands. These versatile machines are used in a variety of applications, from driving compressors to generating electricity, and have become indispensable tools in this sector. As the industry evolves, the use of gas turbines is expanding into new areas, driven by a need to reduce emissions and improve efficiency.
Traditional Applications of Gas Turbines
1. Direct Drive of Compressors
One of the most common uses of gas turbines in the oil and gas industry is as the primary driver for compressors. These compressors are essential for maintaining pressure in pipelines, extracting natural gas, and refining processes. Gas turbines provide the necessary power and flexibility to operate efficiently in these demanding environments.
2. Pumps and Other Rotating Equipment
Gas turbines are also used to drive pumps and other rotating equipment that require high horsepower. This includes pumps for moving crude oil and natural gas through pipelines, as well as equipment used in refining processes.
3. Power Generation
In addition to mechanical drive applications, gas turbines are used to generate electricity on-site. This is particularly important in remote locations where access to the grid is limited or unavailable.
The Shift Towards Electrification
1. Reducing On-Site Emissions
The oil and gas industry is increasingly focused on reducing emissions to meet environmental regulations and obtain air permits. Electrification of equipment is a key strategy in achieving these goals. By replacing gas turbines with electric drives, companies can significantly reduce their carbon footprint and improve air quality at production sites.
2. Grid Connection as the Ideal Solution
The ideal scenario for reducing emissions is to connect equipment directly to the electric grid using electric drives. This approach eliminates the need for on-site combustion, thus reducing emissions. However, the grid is under significant pressure due to the increased demand from these new loads, and securing a grid connection can be a lengthy process.
Temporary Gas Turbines: A Critical Solution
1. Bridging the Gap
Until grid connections are available, temporary gas turbines have become a necessity for many oil and gas operations. These turbines provide the power needed to keep operations running smoothly without interruption.
2. Applications for Temporary Turbines
-
Electric Fracking: Turbines provide power for electric fracturing operations, which require significant energy to pump fluids into the ground.
-
Electric Drilling: Turbines support drilling rigs by generating electricity for electric drives and auxiliary systems.
-
Electric Compression: Temporary turbines power electric compressors used to pressurize natural gas pipelines.
-
Electric Sand Mining: In sand mining operations, turbines supply the power needed to extract and process sand used in hydraulic fracturing.
-
Remote Operations: Turbines provide power to remote operations that are not yet connected to the grid.
Key Features of Gas Turbines for Different Applications
The requirements for gas turbines can vary significantly depending on the specific application in the oil and gas industry. Here are some key features that are prioritized for different uses:
1. Emissions Control
For applications where equipment needs to be added to an air permit, such as on-site power generation, emissions control becomes a critical requirement. Gas turbines with advanced emissions control technologies help meet environmental regulations and reduce the carbon footprint of operations.
2. Mobility and Setup Time
In applications like electric fracking and drilling, mobility and quick setup are paramount. The ability to rapidly deploy turbines and move them between sites ensures operational flexibility and efficiency. This feature is essential for meeting tight project timelines and adapting to changing operational needs.
3. Fuel Flexibility
Fuel flexibility is important in applications where fuel availability may vary. Dual-fuel turbines, capable of operating on both natural gas and diesel, provide operational versatility and ensure continuous power supply regardless of fuel conditions.

Conclusion
Even when equipment is connected to the grid, gas turbines continue to play a vital role in power generation. Many large-scale power plants, including cogeneration (cogen) plants, use gas turbines as a primary energy source. These turbines are highly efficient and capable of providing both electricity and thermal energy, making them a key component of the energy mix.
1. Cogeneration Plants
Cogeneration plants use gas turbines to produce electricity and capture waste heat for additional energy use, such as heating or industrial processes. This increases overall efficiency and reduces emissions compared to traditional power generation methods.
2. Balancing Grid Demand
Gas turbines are used to balance the grid by providing fast response times and adjusting power output as needed. This is crucial for maintaining grid stability, especially with the increasing integration of intermittent renewable energy sources like wind and solar.
