Enterprise to Expand ATEX Pipeline after Successful Open Season

HOUSTON (P&GJ) — Enterprise Products Partners said it will move ahead with the expansion of its Appalachia-to-Texas (ATEX) ethane pipeline after a successful 30-day binding open season.

The 1,200-mile ATEX pipeline transports ethane from the Marcellus/Utica Basin of Pennsylvania, West Virginia and Ohio to Enterprise’s natural gas liquids storage complex in Mont Belvieu, Texas.

The current capacity of ATEX is approximately 145,000 bpd. Enterprise said it is evaluating expansion alternatives that would boost capacity more than 30% to 190,000 bpd – an increase of 45,000 bpd. The incremental capacity is expected to be achieved through improvements and modifications to existing infrastructure.

Houston-based Enterprise said it expects the incremental capacity to be available by 2022.

“The success of the open season reflects the demand for additional, reliable ethane takeaway capacity from the Appalachian region of the country,” said Michael C. “Tug” Hanley, senior vice president, Pipelines and Terminals for Enterprise’s general partner.

“The expansion of ATEX will facilitate growing production from the Marcellus/Utica Basin and will provide access to attractive markets on the Gulf Coast through Enterprise’s integrated midstream network,” Hanley said.
