Enterprise M-U Ethane Pipelines to Gulf Coast Increased Volume in 4Q

In the fourth quarter of 2025, Enterprise Products Partners (EPD) demonstrated growth in its Marcellus/Utica (Appalachian) region operations primarily through its Eastern Ethane Pipeline system (ATEX & Aegis) and increased propane demand in the Northeast. While the majority of the partnership’s newest “major” capital projects are concentrated in the Permian Basin, several items were mentioned in the recent 4Q update that specifically impact or reflect the Marcellus/Utica region.

The two U.S. companies that export ethane, Energy Transfer and Enterprise Products Partners, are both saying that the Trump administration’s temporary block on shipping ethane to China in June gave our export industry a black eye, and China is much less likely to contract for more of our ethane shipments. (Cue the violins.) However, when you consider that China buys half (50%) of our ethane exports, and that ethane exports represent a good chunk of revenue for both companies (both with operations in the Marcellus/Utica), it’s not nothing.
MDN recently brought you the news that the Trump administration was blocking cargoes of ethane to China (see 
Two days ago, RBN Energy reported that ethane and butane exports for Enterprise Products Partners and possibly other NGL exporters were in doubt following a notice received by Enterprise from the U.S. Bureau of Industry and Security (BIS) flagging such exports to China as a security risk (see
RBN Energy is reporting that ethane and butane exports for Enterprise Products Partners and possibly other NGL exporters are in doubt following a notice received from the U.S. Bureau of Industry and Security (BIS) flagging such exports to China as a security risk. Specifically, ethane and butane exports pose an “unacceptable risk of use in or diversion to a military end use.” RBN’s blunt assessment is this: “The BIS decision has the potential to ruin the U.S. ethane market and disrupt global flows.”
Here’s a question: What are the 15 biggest (by company revenue) natural gas-owning pipeline companies in the world? The U.S. has the biggest natural gas pipeline infrastructure in the world, covering a distance of 333,000 kilometers (206,917 miles). Even so, only one U.S.-based company is in the top 5 biggest pipeline companies. Can you guess which country takes the top 2 spots on the list?
We’re always jazzed when we unearth information related to the Marcellus/Utica nobody else has yet discovered or highlighted. We think we’ve found something interesting related to a recently updated spreadsheet maintained by the U.S. Energy Information Administration (EIA). On Friday the EIA published a post to trumpet the news that 19 “liquids” pipeline projects are “moving toward completion in 2021.” In reviewing the list we discovered two projects related to the M-U in 2021, and a third M-U project coming in 2022. All three have an impact on the ability of M-U drillers to move NGL’s out of our region to higher-paying markets.
In August, Enterprise Products Partners, the builder and operator of the Appalachia-to-Texas Express (ATEX) ethane pipeline, launched an open season to gauge interest in expanding the capacity along the 1,192-mile pipeline (see 
In September 2015 MDN brought you the news that two joint venture partners, MPLX (Marathon Petroleum) and Enterprise Products Partners, were actively evaluating a plan to reverse the flow of the 795-mile Centennial Pipeline to send natural gas liquids (NGLs) from the Utica/Marcellus to the Gulf Coast (see
The drama surrounding Williams and whether or not the company will sell itself continues. Energy Transfer Equity’s (ETE) billionaire CEO Kelsy Warren propositioned Williams for over six months before going public with his overtures last year (see 
Corporate raider and Carl Icahn protege Keith “Mini-Me” Meister, Managing Partner of Corvex Management, has launched a full-out assault and takeover attempt of midstream company Williams.
