Let it Flow! ATEX Ethane Pipeline Testing Now, Online Soon
When it comes to carting away lucrative ethane from the Marcellus/Utica, there’s been a horse race between Sunoco Logsitics and their Mariner West pipeline to Sarnia, Canada, and the Enterprise Products Partners and their ATEX (Appalachia-to-Texas Express) pipeline to the Gulf.

The Cornerstone pipeline, as they’re calling it, will stretch nearly 50 miles from the MarkWest cryogenic processing plant in Cadiz, OH northwest connecting to M3’s fractionator plant in Scio and M3’s cryogenic processing plant in Leesville along the way as it terminates and connects to Marathon’s refinery in Canton, OH (see map below). The pipeline will carry, at various times, crude oil, condensate and natural gasoline.
