How M-U NGLs Get Exported – ET’s Mariner Pipelines & Marcus Hook
NGLs, or natural gas liquids, are an essential revenue stream for Marcellus/Utica drillers in the “wet gas” regions of the play. Those regions are found in southwestern Pennsylvania, the northern panhandle of West Virginia, and eastern Ohio. There are several pipelines that flow M-U NGLs to other regions or to export facilities. Among them is Enterprise Products Partners’ 1,230-mile Appalachia to Texas Express (ATEX) pipeline to the Gulf Coast, and Kinder Morgan’s 270-mile Utica-to-Ontario-Pipeline-Access (UTOPIA) pipeline from Harrison County, Ohio, to Windsor in Canada’s Ontario province. However, most M-U NGLs travel through Energy Transfer’s Mariner East and West pipelines, with Mariner East flowing to the Marcus Hook export terminal near Philadelphia.

Commodities like oil and natural gas are just about the purest form of free market capitalism on the planet. They are textbook supply-and-demand commodities. When supply goes up or down, given the same demand, the price for the commodity will go up or down inversely. It doesn’t take long for the markets to “balance.” The same on the demand side. If demand goes up or down and supply stays the same, the price will go up or down. But what about propane? The propane market is different and much harder to predict.


Residents living in the vicinity of Energy Transfer’s Revolution Pipeline cryogenic plant in Bulger (Washington County), PA, got a nasty “present” on Christmas morning. Around 7:30 am, residents report hearing an explosion, followed by a fire, at the plant used to separate NGLs (natural gas liquids, including ethane, propane, and butane) from the raw gas stream that flows through the Revolution gathering pipeline (see
Here in the real world (not the pretend world of leftist radicals who seek to shut down all fossil energy), the Shell ethane cracker finally went online, officially, last week (see 

Earlier this week, Energy Transfer (ET), the builder of the mighty Mariner East pipelines and owner/expander of the Marcus Hook refinery, issued its second quarter update. The company had plenty of positive news to report, including net income of $1.33 billion, a $700 million increase from the same period last year. In July, the company hit a new record high for the amount of NGLs flowing through the Mariner East pipeline system. It has also found a way to squeeze another roughly 10,000 barrels per day of NGL exports out of Marcus Hook.
Antero Resources, one of the largest drillers in the Marcellus/Utica (with major assets in West Virginia), the fifth largest natgas producer in the country and the second largest LNG exporter, issued its second quarter 2022 update yesterday. During 2Q, Antero placed a new compressor station online in West Virginia, boosting Marcellus gas flows by 160 MMcf/d (million cubic feet per day). The new Castle Peak compressor station will be expanded to 240 MMcf/d in 2023. Antero generated $664 million in free cash flow and $765 million in net income during 2Q. Big company. Important company.
God help you if you are a midstream company that has to wade through the mountain of federal regulations and codes generated by agencies including the Federal Energy Regulatory Commission (FERC), and are subject to those agencies’ arbitrary decisions on what they will and won’t enforce. In what amounts to a game of Simon Says, FERC has just fined M3 Ohio Gathering, Utica East Ohio Midstream, and UEOM NGL Pipelines–all three either current or former owners of two tiny NGL pipelines that flow propane and ethane from the Scio (Ohio) fractionation plant–$30,000 for not filling out a particular form over a six-year period. Thirty grand for a paperwork violation. It is, according to lawyers who watch these things, an escalation, an “aggressive expansion of enforcement” on the part of FERC.
The radicals of the Clean Air Council (CAC) are claiming a (very small) victory in their campaign against processing NGLs at the Marcus Hook refinery located near Philadelphia. CAC is CACkling that they have forced Energy Transfer, builder of the mighty Mariner East (ME) pipeline system (a pipeline that CAC couldn’t stop), to back down on how permits are issued for the Marcus Hook facility–the place where NGLs from ME end up for processing and loading for export. The end result is…well…not much. Nothing will really change. The same volume of NGLs will still flow to Marcus Hook, and the same volume of NGLs will be loaded onto ships and exported to other countries. The only thing that changes is that ET spends more time and pays more money to obtain a single large permit instead of two separate, smaller permits. We’ll explain.
