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. Mariner West recently won the race in a photo finish (see “Midstream Knife Fight” – Who Will Have 1st Operational NGL Pipeline to Gulf?). However, Enterprise announced yesterday they are now filling the ATEX pipeline with ethane and testing it. The pipeline should be fully operational by the end of December–months ahead of schedule.
The exciting thing about the ATEX pipeline is it’s connection to four different fractionation (“separating”) plants: two in OH, one each in PA and WV. Why are these two ethane pipelines a big deal? Great question…
