West Virginia has approximately 3,850 miles of natural gas transmission pipeline operated by 7 companies. Most of the network is intrastate — built and operated inside West Virginia — with interstate trunk lines bringing gas in from out-of-state production basins. Columbia Gas Trans Co is the largest operator with 2,062 miles (53.6% of the state total).

West Virginia Natural Gas Pipeline Network at a Glance
189 mi (4.9%) is intrastate — gas moving between fields, storage, and consumers inside West Virginia — and 3,660 mi (95.1%) is interstate, carrying gas across West Virginia’s borders. Every pipeline segment in the EIA dataset is currently flagged Operating; idled and retired transmission lines are not reported in the public data.
| Type | Miles | Segments | Share |
|---|---|---|---|
| Intrastate | 189 | 31 | 4.9% |
| Interstate | 3,660 | 599 | 95.1% |
- 630 total pipeline segments covering ~3,850 miles (EIA transmission dataset)

About the Data on This Map
This map shows interstate and intrastate natural gas transmission pipelines — the high-pressure trunk lines that move gas between production areas, storage, and city gates. It does not show gathering lines (which collect gas from individual wells) or local distribution mains (which carry gas the last mile to homes and businesses).
Pipeline geometries and operator information come from the U.S. Energy Information Administration via its public ArcGIS REST FeatureServer. Per-state stats on this page are computed by intersecting that dataset with the West Virginia state polygon (Census TIGERweb) and summing the intersected segments using haversine distance on the source line geometries. Pipeline diameter, installation year, and capacity are not included in the public dataset. Pipelines that cross West Virginia’s borders are shown in their entirety inside the state polygon, so segments visible on this map may extend into neighbouring states.
