NiSource Midstream Services upgraded its Majorsville compressor station in Dallas, West Virginia, and replaced four Ingersoll Rand KVG412 compressors that were installed in 1956 with four new CAT 3606 engines using Ariel JGC4 compressors.

Installation of the new compressors has augmented capacity at the plant by 1,800 horsepower, providing the opportunity to increase throughput by 70- 80 million cubic feet per day, doubling the previous volume of natural gas delivery.

During the project, NiSource repurposed existing assets and expedited the gathering and delivery of approximately 250,000 dekatherms of Marcellus gas production per day.

The Majorsville system allows the gathering and delivery of liquid-rich Marcellus gas from Washington County, Pennsylvania, and Marshall County, West Virginia, to the MarkWest Liberty Majorsville processing plant. Residue gas from the processing plant is delivered by NiSource Midstream Services into both the Columbia Gas and Texas Eastern interstate pipeline systems.
