Natural Gas Liquids

At first glance, you might think that Phillips 66’s newly announced, $2.2 billion plan to acquire the EPIC NGL pipeline system, two fractionators near Corpus Christi and other NGL-related assets in Texas is just another logical step in the expansion of P66’s “well-to-market” NGL strategy — and you’d be right. But the story is actually much more interesting, involving a long list of well-known midstream players and a long-running, still-evolving effort to dilute the Mont Belvieu NGL hub’s dominance. In today’s RBN blog, we spill the tea. 

In 2024, more than 9 billion gallons of propane were delivered to U.S. consumer markets, primarily for residential heating and cooking, with substantial volumes supporting the commercial, industrial, agricultural and transportation sectors. It is a physically complicated business because, unlike electricity and natural gas, which are delivered through wires and pipelines, respectively, the vast majority of the propane used by U.S. consumers is delivered by some combination of pipelines, rail cars and, ultimately, trucks. How does that complicated supply chain work in real life? In today’s RBN blog, we begin a detailed look at the U.S. propane market. 

LPG and ethane exports out of the U.S. continue to grow rapidly and are expected to reach 3.4 MMb/d by 2030. They are also critical parts of a plan by Enterprise Products Partners to expand its total liquid hydrocarbon exports to 100 MMbbl per month (100 MMb/month), a roughly 50% increase from current levels for crude oil, LPG and ethane, refined products and petchems. In today’s RBN blog, we’ll take a closer look at Enterprise’s LPG and ethane exports and how much they need to grow to reach the company’s ambitious goal. 

Exactly the same product. Exactly the same day. In storage very nearby. Yet their prices diverged by 17 cents per gallon — a spread equivalent to $7 per barrel. That’s a very substantial difference for prices that typically are almost indistinguishable, differing by an average of only 0.3% in recent years. The disparity roiled the financial underpinnings of exports for over a month and busted numerous inventory hedges. Is this some rare commodity? Hardly. It’s Mont Belvieu propane, the Rock of Gibraltar benchmark propane price in the U.S., and to a great extent around the world. But during October there was a crack in that rock a mile wide.

A slew of LPG, ethane and ethylene export projects are underway along the Gulf Coast, a direct result of rising U.S. NGL production and generally flat domestic demand. Three of the projects will provide “flex” capacity of some sort — that is, the facilities will be able to shift between LPG and ethane exports or, in some cases, between ethane and ethylene. In today’s RBN blog, we review the history of U.S. LPG and ethane exports, why midstreamers have been struggling to keep up with export capacity, and how the ongoing addition of flex capacity is likely to play out.

The Gulf Coast is the engine of U.S. energy markets and its fiercely competitive. Over the past decade, monumental growth of crude oil and NGL production, predominantly from the Permian Basin, has led to a surge in exports, with more than 90% of these liquids departing from marine terminals along the Texas and Louisiana coasts. To facilitate that growth, the region has also experienced a tremendous buildout of gathering systems, pipelines, processing facilities, and especially export docks. Major Gulf Coast market regions like Corpus Christi, Houston, Beaumont, Lake Charles and Baton Rouge all have unique advantages and disadvantages. And the companies that operate in those regions have strategic motivations for where they would like to see new volumes go. As the Gulf Coast energy sector presses on to a new horizon, competition for market share among major players is intense, impacting producers, midstream operators, downstream consumers and exporters alike. That was the focus of our recent NACON: PADD 3 conference and it’s the subject of today’s RBN blog. 

Shell’s petrochemical complex in Western Pennsylvania has had plenty of challenges on its way to startup and full operation. Announced a dozen years ago, the project was set back by COVID-related construction delays and a rougher-than-expected production ramp-up. But that’s all in the past now (fingers crossed) and the ethane-rich Northeast finally has its first big ethylene plant. In today’s RBN blog, we’ll examine Shell’s return to plastics and what it took to get there. 

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.

For a few days last week, Canada experienced a nationwide shutdown of its rail transportation network — the backbone of its economy. Of the literally thousands of items railed across Canada to consumers and for export to the U.S. and overseas, we consider three important liquid energy commodities — crude oil, propane and butane — that are transported by rail to provide some perspective on the volumes and dollar values that could have been jeopardized by an extended shutdown. In today’s RBN blog, we summarize the short-lived disruption to Canadian and international commerce and tally the impacts that could have been. 

Crude-oil-focused production in the Bakken still hasn’t fully recovered from its pre-COVID high, partly because the western North Dakota shale play continues to face takeaway constraints, especially for natural gas and NGLs. A couple of NGL pipeline projects in the works will certainly help, but will they be enough to enable the Bakken’s increasingly consolidated E&P sector to ramp up its crude oil production? And one more thing: How will the incremental NGLs flowing south on Kinder Morgan’s soon-to-be-repurposed Double H Pipeline find their way to fractionation centers in Conway and Mont Belvieu? In today’s RBN blog, we’ll look at the Bakken’s complicated production-vs.-takeaway conundrum and the ongoing efforts to address it. 

Fast-rising NGL supplies during the early years of the Shale Era fueled excitement about the potential for new petrochemical plants in the U.S., especially ethane-only crackers to make ethylene and other byproducts, along with propane dehydrogenation (PDH) plants to make propylene. While 11 new ethane-fed crackers have come online in the U.S. since the mid-2010s and the world’s largest — Chevron Phillips Chemical and QatarEnergy’s 4.8-billion-lb/year facility — is under construction in Texas, only three of the many PDH projects proposed over the same period were actually built. In today’s RBN blog, we’ll look at why the initial rush of new PDH project announcements resulted in so few new U.S. plants. 

Mont Belvieu, TX and Conway, KS, are the two most significant U.S. hubs for NGL trading, storage and fractionation, with the much bigger Mont Belvieu hub primarily serving Gulf Coast and export demand, while the smaller Conway hub is focused on Midwest/Great Plains demand, especially for propane. The pricing dynamics between the two hubs are a key indicator of the supply/demand balance between the regions, but they don’t have the same kind of influence over the direction or magnitude of flows as price differential dynamics often do for other energy commodities. In today’s RBN blog, we will examine the gap between the price of the NGL “basket” in Mont Belvieu versus Conway and what that price spread tells us. 

Energy Transfer’s plan to buy WTG Midstream, a West Texas-based and private equity-backed natural gas gatherer and processor, just got a bit less expensive — and not quite so comprehensive. Energy Transfer will still acquire WTG’s network of more than 6,000 miles of gas pipelines, eight processing plants and more, but WTG’s 20% stake in the joint-venture (JV) BANGL pipeline system is no longer part of the deal. In today’s RBN blog, we’ll take a look at the detour from the original transaction. 

With an announcement in late 2023 by Dow Chemical that it would be undertaking an enormous expansion of its ethylene production site in Fort Saskatchewan, AB, it was immediately clear that Alberta’s ethane supplies would need to increase by a significant 110 Mb/d. As we’ll discuss in today’s RBN blog, a deal was signed in February between Dow and Pembina Pipeline Corp. that calls for the midstreamer to provide up to 50 Mb/d of additional ethane supplies and, according to executives at Pembina’s investor day earlier this month, will require the company to invest between C$300 million (US$220 million) and C$500 million (US$367 million) to build out its existing NGL/ethane infrastructure.
