NiSource Completes Compressor Upgrade In West Virginia

October 2013, Vol. 240 No. 10

NiSource Midstream Services has completed a compressor upgrade project at its Majorsville compressor station in Dallas, WV. The project included replacement of four vintage Ingersoll Rand KVG412 compressors with four 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 MMcf/d, doubling the previous volume of natural gas delivery.

“Infrastructure needs are increasing as the natural gas industry continues to grow in West Virginia and Pennsylvania,” said Chad Zamarin, COO of NiSource Midstream Services.
The Majorsville gathering system and compressor station was developed as part of the first integrated gathering and processing system serving Marcellus production in southwest Pennsylvania and northern West Virginia. NiSource Midstream Services repurposed existing assets to meet customers’ needs and expedited the gathering and delivery of 250,000 Dth/d of Marcellus gas production.

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