U.S. Propane Exports Grow Faster Than Production; Will It Continue?

The EIA report on propane inventories that came out yesterday was a shocker. This time of year, stocks are supposed to be building toward the levels needed to get U.S. propane markets through the winter season. But the numbers released on Wednesday showed an inventory decline, resulting in inventory balances now below the five-year minimum. The culprit, of course, is exports, with 1.4 MMb/d of them reported last week, a 17% gain over the year-to-date average. And these cargoes to overseas markets are happening even with propane prices in the stratosphere: more than double where they stood this time last year. Propane marketers were hoping that higher prices would slow down exports, but so far that is not happening. In today’s blog, we examine U.S. exports of LPG — propane plus butane — and discuss what may be ahead for these markets.

Since 2011, U.S. natural gas liquids (NGL) production has more than tripled, while domestic demand has grown only modestly. Consequently, the only way NGL markets could balance was a dramatic increase in exports. Today, over 70% of U.S. propane production is exported, with the majority going to overseas markets, while other NGLs see varying export levels: 40% for butanes, 25% for natural gasoline, and 18% for ethane. Although U.S. NGL production growth is slowing, we still project an increase of 1.5 MMb/d over the next decade and a half, with 85% of that growth coming from the Permian Basin. As U.S. ethane and LPG production continues to rise, nearly all the export growth is expected to head to the Asia/Pacific region, with a significant portion going to one country: China. But is this outlook for U.S. NGLs realistic? And do we have adequate infrastructure — ranging from gathering systems to processing plants and fractionators, and from export terminals to the right kind of ships — to handle all of these volumes? In one of his hit tunes, Toby Keith clearly identified the problem for us: “Where You Gonna Go? And What Ya Gonna Do When You Get There?” These are key NGL market themes that we'll be exploring at our upcoming NACON conference on October 24 at the Royal Sonesta Hotel in Houston and that we’ll introduce in today’s RBN blog.

With U.S. NGL production hitting a record high of just over 4.0 MMb/d in the fourth quarter of 2017 and ethane production also reaching record volumes at 1.6 MMb/d, the price for ethane has remained stuck at about 25 c/gal — where it’s been for the past two years, even though prices for other NGLs are up over the same period. The combination of roaring high-ethane-content Permian and SCOOP/STACK NGL volumes, coupled with steam cracker outages and construction delays due to Hurricane Harvey, have landed us here. So where do we expect the ethane market to go now as incremental cracker and export demand ramp up in 2018 and 2019? Today, we continue a series on our updated NGL market forecast, highlighting the NGL product whose market is going through the most changes: ethane.
