Steam Crackers

In just over a month, the price of Mont Belvieu purity ethane doubled, from 19 c/gal to 39 c/gal on Friday. Sure, the price of natural gas was up about 15% over the same period. But that increase was nowhere near ethane’s, so it was certainly not the price of gas that was making ethane take off. In fact, with ethane rocketing into space and gas prices still in the dumper, the ethane-to-gas ratio — a key measure of the value of ethane — skyrocketed, soaring from 1.2X in mid-June to 2.2X on Friday. A ratio at this level has only happened twice before in the past decade: once in 2018 due to a collision between fractionation capacity and new petchem plants coming online, and then again in 2020 during the COVID petchem demand surge. But the most recent price surge didn’t last long. On Tuesday ethane came back to earth, crashing 22% in a single day, and the ethane-to-gas ratio deflated down to 1.6X. So what’s happening? There are a lot of conspiracy theories out there that we won’t repeat here. Instead, in today’s RBN blog, we’ll lay out what we think are the most likely contributing factors behind this wild ride.

Over the past few years — and with a big boost from Permian production growth — the South Texas coast has transformed itself into a top-tier hub for hydrocarbons. Crude oil exports stand out, of course, with marine terminals in Corpus Christi/Ingleside accounting for 60% of U.S. export volumes in 2022. But Corpus also is home to the nation’s second-largest LNG export terminal (which is now being expanded), as well as a half-dozen refineries, and the broader region has the Agua Dulce natural gas hub, nine NGL fractionation plants, and four massive, NGL-consuming ethylene plants, including ExxonMobil/SABIC’s giant new steam cracker in San Patricio County. All of these assets are interconnected by a maze of crude oil, natural gas, NGL, “purity product,” and ethylene pipelines. And the region is well-positioned for additional growth as crude, gas, and NGL production in Texas continues to increase. In today’s RBN blog, we discuss our latest product: a digital, interactive map that helps makes sense of a spaghetti bowl of pipelines, plants and related assets in South Texas.

That crazy little ethane molecule is at it again. Yesterday the price blasted to 67.875 c/gal, a level last seen on January 17, 2012. Petchem cracker margins are low. Production is up, but inventories are down. A big driver of the bedlam is the price of natural gas, trading in the $7-$9/MMBtu range for the past month. But as usual with ethane, there’s a lot more happening below the surface — including high domestic demand, growing export volumes, and significant developments in downstream petrochemical markets — all shaking things up. Looking ahead, uncertainty looms, with more export capacity, ever-changing ethane rejection economics, and uneven production growth. In today’s RBN blog, we’ll leap back into the ethane market to see what’s been going on, and where ethane is headed over the next few years.

It’s been over a month since the Deep Freeze swept across Texas, shutting down the power grid, curtailing natural gas supplies, and generally wreaking havoc on the state’s population and infrastructure. The petrochemical industry was hit particularly hard, with every ethylene-producing steam cracker in the state and many in nearby Louisiana forced into hard shutdowns — that is, production coming to a screeching halt with little or no preparation. The result was unit damage well beyond what typically happens with other weather-related events like hurricanes, where there is usually some ability to manage an orderly shutdown. Consequently, at least half of the industry’s capacity to produce ethylene and its by-products remains offline, a development that is ricocheting through supply chains across the economy. Today, we examine the magnitude of the damage, consider what is happening in ethylene markets — the epicenter of the turmoil — and contemplate the longer-term implications of the outages. 

After several years of development, Shell’s $6 billion Pennsylvania Petrochemicals Complex — the first of its kind in the Marcellus/Utica shale play — is really taking shape about 30 miles northwest of Pittsburgh. The facility, which will consist of a 3.3-billion-lb/year ethylene plant and three polyethylene units, is in its final stages of construction, as is a pipeline that will supply regionally sourced ethane to the steam cracker. When the Falcon Pipeline and the PPC comes online, possibly as soon as 2022, they will provide a new and important outlet for the vast amounts of ethane that is now either “rejected” into natural gas for its Btu value or piped to Canada, the Gulf Coast, or the Marcus Hook export terminal near Philadelphia. Today, we discuss progress on the Marcellus/Utica’s first world-class petrochemical complex and what it will mean for the play’s NGL market.

How about some good news to start the year? Over the past few weeks, ethylene margins have blasted into the stratosphere. These are good times for steam crackers, those petrochemical plants that use mostly NGL feedstocks to produce ethylene and other building-block chemicals. As you might expect, this newfound prosperity has a lot to do with ethylene’s price. In December alone, the price of ethylene was up 50%; versus April it’s up a whopping 4X, coming in yesterday at 37.5 cents per pound (c/lb). There are a whole range of factors responsible, including petchem outages due to the hurricanes, new downstream derivative units coming online, robust exports from the Enterprise Morgan’s Point dock, and, oh yes, strong demand for downstream products — everything from food packaging to construction materials. Is the spike in ethylene prices going to last? And what does it mean for NGLs, which account for more than 95% of the feedstock supply for U.S. ethylene. We’ll explore those questions and more in this blog series we begin today.

Petrochemicals form the backbone of modern consumer society. They provide the plastics and other materials needed to make most of the products we depend on, everything from computers and cellphones to car tires and fertilizer — not to mention N95 masks and other personal protective equipment. Petrochemicals come from crude oil, natural gas, and/or NGLs like ethane and propane, of course, and a good way for an energy-producing area to add value to its raw hydrocarbons is to develop petchem plants nearby. Alberta, Canada’s leading energy-producing province, is making a new push to encourage such projects. Today, we discuss the latest provincial program and what it hopes to accomplish.

The South Texas NGL market has always been a world of its own, a self-contained liquids ecosystem running from Brownsville to Markham, a distant 200 miles from the NGL epicenter at Mont Belvieu. In recent years, however, the South Texas market has been undergoing radical change, first with the emergence of the Eagle Ford basin, then with the onslaught of Permian production and, most recently, with the aptly named EPIC NGL Pipeline and new fractionation capacity in greater Corpus Christi. More supply and demand are on the way, with new pipes, exports, and the largest ethane-only petrochemical plant in the world under construction. And with these developments, a strategy by several large, well-financed players has emerged – to develop an NGL storage and fractionation hub competitive with Month Belvieu. Today, we begin a series to examine the South Texas NGL market and how changes there will impact flows, utilization, and pricing across North America and beyond.

Energy markets balance — eventually. In the midst of the turmoil we’ve experienced this year, there have been periods when it seemed like markets were going to hit the wall. But even with the historic WTI oil price glitch on April 20, the physical crude oil markets continued to function. That’s the way it is supposed to work, and it’s good news. The bad news is that figuring out how these markets are balancing in these volatile conditions can be challenging if not downright perplexing. Nowhere is that more true than the market for U.S. propane. Production is down, but so is demand. Inventories are up, and so are prices. Propane continues to be exported, even though global demand has been whacked by COVID. In today’s blog, we explore these developments and put the spotlight on RBN’s NGL Voyager, our subscriber report and data service that we have just reformatted, upgraded and generally reconstructed to meet the information needs of today’s NGL marketplace.

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.
