Enterprise Products Partners doesn’t just extract mixed NGLs from associated gas at processing plants, transport that Y-grade to the NGL hub at Mont Belvieu, and fractionate NGLs into “purity products” like ethane, propane and butanes. The midstream giant also distributes purity products to Gulf Coast steam crackers and refineries, converts propane to propylene at its two propane dehydrogenation (PDH) plants, distributes ethylene and propylene, transports propane and butane to wholesale markets across much of the eastern half of the U.S., and exports a wide range of products — ethane, LPG, ethylene and propylene among them — from two Enterprise marine terminals on the Houston Ship Channel. (Another export terminal in Beaumont, TX, is in the works.) Talk about a value chain! In today’s RBN blog, we continue our series on NGL networks with a look at Enterprise’s NGL and petrochemical production, distribution and export assets.

Amid all the turmoil and negative news in energy markets this year, U.S. propane has been the exception, turning in a stellar performance. Even with exports up almost 10% in November from the same period last year, averaging 1.3 MMb/d for the month, inventories remain in good shape at 92.6 MMbbl, or about 5% above stocks in November 2019. Part of the reason has been strong production numbers, which are down only 5% since January, and up a whopping 14% since May. Weather has been another contributor to robust stock levels, with November 2020 coming in as one of the warmest on record. But winter is just arriving. And with export volumes now greater than total U.S. winter consumption, market dynamics have shifted. It now takes more inventory in the ground throughout the winter to support the combination of U.S. demand and exports. But how much more inventory is enough? And how should we factor in the potential for further increases in exports? At the same time, the market is still facing the possibility of another round of declining production due to COVID-related drilling cutbacks. This blog series is about making sense of what’s going on in the propane market today, and what may be coming up in the months ahead. 

During the last two weeks of April, a barrel of propane in Mont Belvieu was more expensive than a barrel of WTI crude oil in Cushing. That’s never happened before. You might think that such an aberration could be blamed on the wacky April-May 2020 COVID crude market, but that is only part of the story. Propane production is falling and pre-COVID projections of continued supply growth are out the window. But new gas processing plants, pipelines, fractionation facilities, dock capacity and downstream demand have come online in recent years, in anticipation of those ill-fated additional supplies. Already we are seeing flows, price relationships and differentials convulsing in response to the new reality, and projections of future supply/demand imbalances suggest a previously unthinkable possibility: a market that can’t get enough propane supply, especially if the winter of 2020-21 is a cold one. In today’s blog, we will explore the evidence of these market developments that is already visible and look to what may be ahead for propane supply and demand.
