Over the past nine months, the frac spread —a rough-cut measure of the value of extracting NGLs from raw gas at gas processing plants — has taken a terrifying plunge, from $9.82/MMBtu in early March to only $2.16/MMBtu on Monday. Given that the frac spread is the differential between the price of natural gas and the weighted average price of a typical barrel of NGLs on a dollars-per-MMBtu basis, a 78% nosedive like that suggests that something is seriously out of whack, and that at least some market players are taking a real hit financially. In today’s RBN blog, we discuss the frac spread, the drivers behind its recent freefall, and what it would take for gas processing margins to rebound.

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.

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.

The energy world has been turned upside down in 2020 by COVID-19, resulting in the cancellation, scaling back, or deferral of numerous pipeline projects in both the U.S. and Canada. One such deferral involved a planned NGL pipeline that would run through the heart of Alberta’s Montney and Duvernay plays. Originally slated to begin construction earlier this year, a one-year deferral was announced back in May by the joint venture of Canadian midstream players Keyera and Energy Transfer Canada, the latter of which is itself a JV of Energy Transfer and KKR. Since then, a stabilization in energy markets and signs of recovery in Alberta NGL production has provided the co-developers with the confidence to commit to a construction start in 2021. Today, we review the project and what has changed to get it back on track.

Over the past 10 years, there’s been a 14-fold increase in U.S. LPG exports: from 132 Mb/d, on average, in 2010 to 1.85 MMb/d so far in 2020. That extraordinary growth in export volumes couldn’t have happened without the development of a lot of new, costly infrastructure — everything from gas processing plants, NGL pipelines, and fractionators to LPG storage capacity, marine terminals, and ocean-going gas carriers. And that build-out continues, not only along the Gulf Coast but on the shores of the Delaware River near Philadelphia. Energy Transfer has been working to expand the throughput of its Marcus Hook terminal on the Pennsylvania side of the river, and Delaware River Partners, an affiliate of Fortress Transportation & Infrastructure, will soon be transloading LPG from rail tank cars onto ships across the Delaware in New Jersey. Today, we discuss Delaware River Partners’ Gibbstown Logistics Center.

If you’ve filled up the tank in your car, SUV, or pickup in the past few days, you probably bought your first batch of winter-blend gasoline since the spring. It’s unlikely that you noticed a difference — only a refining geek with a nose for this sort of thing would — but winter gasoline has a higher Reid Vapor Pressure than summer gasoline, and therefore evaporates more quickly and emits more fumes. There’s a logic to EPA’s mandated switchover from lower-RVP gasoline to higher-RVP gasoline each September, and their switch back to lower-RVP each April/May. For one thing, using different gasoline blends during the colder and warmer months helps ensure that your engine runs well year-round; for another, reducing gasoline vapor pressure in the summer reduces emissions that contribute to smog. Today, we discuss gasoline RVP, why it matters, and how refineries ramp it up and down. (A hint is in the blog’s title.)

Pipelines are lifelines to refineries, steam crackers, and other consumers of energy commodities, and even the hint that a major pipeline may be shut down raises big-time concerns. For evidence, look no further than Enbridge’s Line 5, which batches light crude oil and a propane/normal-butane mix across Michigan’s upper and lower peninsulas and to points beyond. One of Line 5’s two pipes under the Straits of Mackinac is temporarily out of service, halving the 540-Mb/d pipeline’s throughput, and Michigan’s attorney general continues to pursue a lawsuit that, if successful, could be Line 5’s death knell. Enbridge also is facing a fight on its plan to replace the twin underwater pipes with a new, safer “tunnel” alternative. All of which raises the question, what would be the market effects if Line 5 is permanently closed? Today, we conclude a miniseries on one of the Upper Midwest’s most important liquids pipelines.

The Dakota Access Pipeline isn’t the only interstate liquids pipe facing an uncertain future. The fate of Enbridge’s Line 5, which batches either light crude oil or a propane/butanes mix from Superior, WI, through Michigan and into Ontario, also hangs in the balance as the company renews its battle with Michigan’s top elected officials to keep the 67-year-old pipeline open and its effort win regulatory approval to replace the pipe’s most important water crossing. Line 5 supporters say that closing the 540-Mb/d pipeline would slash supplies to residential and commercial propane consumers in the Great Lakes State, steam crackers in Ontario, and refineries and gasoline blenders in three states and two Canadian provinces. Critics of Line 5 counter that there are plenty of supply alternatives. Today we discuss the pipeline, what it transports, and who it serves, as well as challenges it faces.

Over the past five years, the production of natural gas liquids from gas processing plants has soared by almost 2 million barrels per day (2 MMb/d), or about 60%. That has been great news for natural gas producers, processors, and end-use markets. But there is a catch: the rate of production does not match up with demand. While production is a steady, “ratable” volume, demand is anything but ratable. Demand swings with the gasoline blending season, cold weather (or lack thereof) in the propane market, export demand, petchem feedstock economics, the impact of COVID-19 on transportation fuels, and a myriad of other factors. The flywheel that balances supply and demand on any given day is storage. Not just any storage, though. For NGLs, storage of large volumes means salt caverns. Huge caverns thousands of feet below the surface. Today, we update one of RBN’s Greatest Hits blogs and take a deep dive into the history of NGL storage — all the way back to Smoky Billue.

Since the mid-2010s, MPLX has been developing a far-reaching pipeline system for delivering heavier natural gas liquids and field condensate from the Utica and “wet” Marcellus plays to Midwest refineries for gasoline blending and refining, and to the Alberta oil sands for use as diluent. The multi-year, multi-project effort, which has involved the construction of new pipelines, the repurposing of existing pipes, and the development of new storage capacity, will reach another milestone next month, when MPLX starts batching normal butane and isobutane through most of the pipeline system. And further enhancements are on the horizon. Today, we provide an update on the master limited partnership’s long-running strategy for moving Marcellus/Utica-sourced liquids to market more efficiently and at a lower per-barrel cost.
