Much as production growth in the Permian required the development of new pipeline capacity to take away crude oil, natural gas and NGLs, increasing activity in the Williston Basin has spurred the need for incremental capacity to move all three of the energy commodities out of western North Dakota and eastern Montana. For NGLs, the recent start-up of ONEOK’s Elk Creek Pipeline has been the answer to producers’ prayers — not just in the Williston Basin (home of the Bakken formation), but also in the Rockies’ Powder River and the Denver-Julesburg (D-J) basins, through which the new, 240-Mb/d pipeline passes on its way to Bushton, KS. Elk Creek’s timing couldn’t have been better: it came online just as a number of new gas processing plants entered commercial service in the Williston Basin, and just in advance of possible Btu restrictions on the all-important Northern Border gas pipeline that may force cutbacks in ethane rejection. Today, we explain why the Elk Creek NGL Pipeline helps resolve a number of challenges Bakken producers have been facing.

Propane stockpiled in Canada has often been a mid-winter godsend for propane consumers in the U.S. Midwest and Great Plains states. If supplies in PADD 2 ever got tight due to unusually cold weather, greater-than-normal crop-drying demand and/or kinks in the U.S. supply chain, the higher prices spurred by the shortfall would incent more Canadian propane to be piped, railed or trucked south. This winter may be different, though. A new propane export terminal in British Columbia and steady-as-she-goes exports from the U.S.’s northern neighbor to PADDs 2 and 5 have left Canadian propane inventories nearly one-third lower than a year ago, and propane in the Edmonton, AB, hub is selling at a far-from-typical premium to propane at Conway, KS, and Mont Belvieu, TX. Today, we explain why a supply-demand imbalance in the U.S. heartland this winter might be harder to fix.
Cold weather and spiking demand from Midwest and Great Plains farmers trying to dry their late-maturing, soggy crops have sent the PADD 2 propane market into a tizzy. Supply is not a major issue — propane inventory levels in the region are only a little below average, and stocks are plentiful along the Gulf Coast in PADD 3 — but distributing propane by rail and truck for crop-drying use has been a bigger-than-normal problem. As a result, farmers are scrambling to get more of the fuel, and propane prices in the U.S. heartland have been skyrocketing. Worse yet, Canada may not be able to come to the rescue as it has in the past, because its propane exports to Asia are up and its inventories are down. Today, we review recent developments on the fuel front in the nation’s breadbasket.
Anything but normal might be the best way to characterize today’s market for normal butane. Butane production at gas processing plants and fractionators is at or near an all-time high. Butane consumption by steam crackers is maxed out, and so were butane exports until new dock capacity came online this fall. Butane inventories? They’ve risen to record levels too, and this summer, butane prices fell to their lowest mark in more than a decade. Now, with winter-gasoline blending season in high gear and new room for export growth, butane prices at Mont Belvieu are up more than 35% from where they stood a month and a half ago. What does all this mean for the butane market this winter? Today, we discuss recent trends in normal butane production, consumption, exports and stocks.
U.S. propane production has been on the rise for most of 2019, but propane consumption by steam crackers has been reined in by poor economics, and propane exports have been constrained by export-capacity shortfalls. That’s led to a big buildup in propane inventories, which stand at near-record levels as the market prepares for a winter heating season that is forecasted to be milder than normal. So we’re in for only a modest draw on propane stocks between now and spring, right? Not necessarily. There’s change in the air regarding propane supply, cracker demand and export capacity and, as we learned in the balmy winter of 2016-17, the U.S. propane market isn’t nearly as dependent on the weather as it used to be. Today, we assess recent market developments and explain why a big decline in propane stocks is a real possibility.
Demand for ethane from U.S. steam crackers is rising as recently completed ethane-only crackers ramp up to full production and additional crackers are finished. To keep pace with demand growth, a portion of the ethane now being “rejected” into the natural gas stream and sold for its Btu value will instead need to be left in the mixed-NGLs stream and fractionated into purity-product ethane. This raises two questions. First, in which shale plays will this shift from ethane rejection to ethane production occur? And second, how much will ethane prices need to increase to encourage the shift and make the required incremental volumes of ethane available? Today, we continue a series on ethane-market developments with a look at where the next tranche of ethane supply will come from and how high ethane prices might need to rise.
The U.S. ethane market has experienced major ups and downs in the past couple of years. First, there was sharply rising demand from new steam crackers, a fractionation-capacity crunch and soaring ethane prices. Then came an ethane demand slump, plummeting prices and a big jump in inventories. More recently, though, the market seems to have returned to a state of relative equilibrium. Ethane prices have settled in — at least for now — at about 22 cents/gallon (gal), a couple of pennies below where they had been standing rock-steady before all hell broke loose. Ethane demand from existing steam crackers is rising again, and new cracker capacity is coming online. The questions now are, with demand on the upswing, will ethane prices be rising too — and, if so, by how much? And what does that mean for steam cracker economics? Today, we discuss recent developments in the ethane market and explain why there’s good reason to believe that ethane prices won’t be spiking anytime soon.
The ethane market isn’t for the faint at heart — it’s got lots of ups and downs, and it’s impacted by an unusually wide range of variables. A year ago this month, a combination of fractionation constraints in Mont Belvieu and rising demand from new ethane-only steam crackers sent ethane prices north of 60 cents/gallon. For most of the time since then, though, ethane prices were in something close to freefall, bottoming out at only 10 cents in late July before rebounding in recent weeks to 20 cents or so. During the big, months-long price decline, ethane traders and cracker operators did what anyone does when they can buy something they’ll need in the future for next to nothing — they stocked up. Today, we examine recent trends in ethane supply, demand, prices and storage levels, and take a look ahead.
Energy markets are constantly changing, but pipelines can take years to complete, and once they’re in the ground, that’s where they stay. Therefore, it’s critical for midstream companies to build as much flexibility as possible into their plans for new pipelines and other infrastructure, because you never know what the markets for crude oil, natural gas, NGLs and refined products might have in store. Energy Transfer apparently has that flexibility in mind as it’s been building out its Mariner East pipeline system across Pennsylvania to the Marcus Hook Industrial Complex (MHIC) near Philadelphia. Today, we consider recent developments regarding these key midstream assets in the Northeast and their still-evolving uses.
For a few days in late July, the price differential between propane stored at Enterprise Products Partners’ salt caverns in Mont Belvieu, TX, and propane stored at facilities owned by others a few hundred yards away quickly widened to as much as 10 cents/gallon. That’s by far the biggest spread of its type we can recall, and while we can’t say for certain what caused the “Enterprise-vs.-others” propane differential to blow out, there’s a likely — and familiar — culprit: NGL infrastructure constraints. Something else this unusual pricing event confirmed is that, no matter where the NGL storage, fractionation or pipeline constraint may occur, it almost always has an outsized effect on the much smaller NGL storage and fractionation hub in Conway, KS. What’s with that? Today, we look at the recent, rapid slide in propane prices at Enterprise’s Mont Belvieu storage facility and discuss what it tells us.
By the third quarter of next year, the Enterprise Hydrocarbons Terminal (EHT) on the Houston Ship Channel will have the capacity to export nearly 1.1 MMb/d of LPG — 435 Mb/d more than it can today. Also, Targa Resources and Energy Transfer are each planning 200-Mb/d expansions at their LPG export docks along the Texas Coast, and Phillips 66 and MPLX may very well be announcing projects of their own soon. All this suggests that there will be ample dock space available to propane and butane shippers if, as we expect, LPG volumes continue to ramp up in the 2020s. And, with Enterprise Products Partners’ promise to offer super-competitive rates at EHT, shippers are likely to enjoy low send-out costs. Today, we discuss recent developments on the propane/butane marine-terminal front and what they mean for LPG shippers and exports.
When it comes to U.S. NGL exports, propane and ethane grab most of the attention. Each accounts for a big share of the typical NGL barrel, and ethane exports are a frequent topic of conversation because of the potential for growth — especially if the U.S. and China find a way to end their trade war. But three other so-called NGL “purity products” — normal butane, isobutane and natural gasoline — are being exported in increasing volumes too, providing important supplemental revenue to NGL producers and marketers. What’s their story? Today, we look at the export volumes and destinations of three often overlooked purity products.
The margin for producing ethylene by steam-cracking ethane has been less than a dime per pound since mid-March 2018, and less than a nickel for nearly nine of the past 15-and-a-half months. In fact, for two weeks last September, the ethylene-from-ethane margin fell below zero. And yet, a joint venture of two of the world’s savviest companies — energy giant ExxonMobil and petchem behemoth Saudi Basic Industries Corp., or SABIC — recently committed to building what will be the world’s largest ethane steam cracker: a 4-billion-pounds/year facility to be constructed near Corpus Christi by 2022. Is this a case of blind optimism? No, not when you factor in the cracker’s location, the JV’s concurrent plan to construct two polyethylene plants and a monoethylene glycol plant right next door, and the co-developers’ global market reach. Today, we discuss the thinking behind ExxonMobil and SABIC’s big investment in Texas’s San Patricio County.
U.S. ethane exports have risen steadily over the past five years, from next to nothing in early 2014 to an average of 255 Mb/d in 2018 and 269 Mb/d in the first three months of this year. But unlike its heavier NGL siblings propane and butane, which are in demand globally as fuels and feedstocks, ethane’s only established use is in steam crackers specifically equipped to process it, so there are only a few countries where exported ethane is likely to end up. Also, the waterborne transport of ethane is generally limited to specially designed ethane carriers, and there aren’t many of those around because of ethane’s restricted market. All this makes for an export commodity that stands apart. Today, we review the evolution of U.S. ethane exports and the challenges to export growth posed by the U.S./China trade war.
It’s impossible to know for certain what will happen next in the international markets for propane, butane and ethane — there are too many variables and vagaries. What is very doable, though, is to gain a better understanding of the broader market forces at play. For example, the U.S. now has a few years under its belt as a major propane exporter, so it’s feasible to assess trends in where that propane is going — or no longer going — and to examine how propane exports to various parts of the world are impacted by everything from a high-stakes trade war to governmental efforts to encourage the use of cleaner cooking fuel. Today, we continue our deep-dive into propane, butane and ethane exports with a look at where propane exports from the U.S. East, West and Gulf coasts are heading, and why.
