My guess would be the big time natural gas compressors used to push the gas from the mid stream gathering and dehydrating facilities to the end user utility’s. Sometimes these pipelines can go hundreds or even a thousand+ miles. For example, my grandfather worked for Washington gas and light co. For 35 years. One of the sources for DC and the surrounding areas’ natural gas was for a long time, and probably still is from the Gulf of Mexico. Engines such as this likely push the gas thru the pipelines between the gulf and DC.
