Pipeline Flows

It's been almost a year since the co-owners of the massive Capline crude oil pipeline initiated southbound service between Patoka, IL, and St. James, LA, on what for a half-century had been a northbound conduit. How’s it working out? So far, so good, it seems. As expected, for the first several months the volumes of heavy Canadian crude oil flowing down the 632-mile, 40-inch-diameter pipeline to the St. James hub were modest. Since June, however, Capline has been offering a temporary incentive rate to attract more heavy oil, and starting December 1 it’s also been offering a temporary buck-a-barrel rate for light oil too. In today’s RBN blog, we discuss the latest Capline developments, the challenges associated with batching heavy and light crude on such a big pipe, and the prospects for much higher flows.

The battle to restore energy reliability in Europe has breathed new life into North American LNG export projects — and into the Haynesville Shale in Louisiana, the closest supply basin to many of the planned and proposed liquefaction facilities. Gas production in the region has climbed more than 4 Bcf/d — an impressive 39% — since 2019 and we expect it to grow nearly as much over the next three years. The big question on everyone’s mind, however, is whether there will be enough pipeline capacity to move that gas to where it’s needed on the coast. Pipeline capacity for southbound flows through the Bayou State is already showing signs of stress. Will recently completed and upcoming debottlenecking projects help stave off major supply and pricing disruptions? In today’s RBN blog, we provide our outlook on Haynesville production and the nature and timing of Gulf-bound pipeline projects.

Just downstream from the Appalachian supply basin — where daily spot natural gas prices are among the lowest in the country — cash and forward prices in the Mid-Atlantic and Southeast have rocketed, becoming the highest gas prices in the land, and in some cases are at never-before-seen levels for this time of year. No doubt it’s been a sweltering summer so far, and low storage levels aren’t helping either. But there’s more to the price premiums than that. Limited access to supply and constraints on Williams’ Transco Pipeline — the primary system delivering gas to the region — have created a demand “island” there just as persistent heatwaves boosted cooling demand. Moreover, without additional pipeline capacity, the dynamics unfolding this summer could become a regular feature of the Southeast/Mid-Atlantic markets. In today’s RBN blog, we break down the factors driving regional prices to new heights.

This year has been a mixed bag for Appalachian natural gas producers. Outright prices in the region are higher than they’ve been in a few years, thanks to lower storage inventory levels and robust LNG export demand. However, regional basis (local prices vs. Henry Hub) is weaker year-on-year as higher production volumes have led to record outbound flows from Appalachia and are threatening to overwhelm existing pipeline takeaway capacity. Last month, Equitrans Midstream officially announced that the start-up of its long-delayed Mountain Valley Pipeline (MVP) project will be pushed to summer 2022 at the earliest. Then, just last week, outbound capacity took another hit as Enbridge’s Texas Eastern Transmission (TETCO) pipeline was denied regulatory approval to continue operating at its maximum allowable pressure, effectively lowering the line’s Gulf Coast-bound capacity by nearly 0.75 Bcf/d, or ~40%, for an undefined period. Today, we consider the impact of this latest development on pipeline flows, production, and pricing.

What started out as a novel snow day for parts of Texas, replete with Facebook posts full of awestruck kids and incredulous native Texans, quickly escalated to a statewide energy crisis last week. A lot of the state’s electric generation and natural gas production capacity was iced out just when demand was highest, sending gas and electricity prices soaring and leaving millions without power for days. Frigid temperatures like the ones we saw would register as a regular winter storm in northerly parts of the U.S. and in Canada — but in Texas? A disaster. Market analysts, regulators, and observers will be unpacking the events of the past week — and the many implications — for a long time to come. We may never know the full extent of the chaos and finagling that went on among traders and schedulers behind the scenes as they tried to wrangle molecules. However, we can get some insight into the madness using gas flow data to provide a window into how the market responded and, in particular, the effect on LNG export facilities. Today, we examine the impacts of Winter Storm Uri on Gulf Coast and Texas gas movements.

With the rise of LNG feedgas demand in southern Louisiana, physical natural gas flows at Henry Hub have been climbing. As such, volumes moving through the U.S. benchmark pricing location are increasingly affected by swings in LNG feedgas deliveries, as well as in the gas supply flows into southern Louisiana that serve that demand. Those impacts have become particularly evident in recent months as nearby LNG export capacity utilization went from a trough this summer due to cargo cancellations, to being erratic during late summer and fall as hurricanes disrupted marine traffic and facility operations, and, in more recent days, to being at full bore at most facilities. In conjunction with brimming storage and pipeline maintenance in the area, this has meant more operational constraints and volatility in flows and pricing at the hub. Today, we continue our series on the changing dynamics in and around Henry Hub. 

Since August, physical natural gas flows at Henry Hub have been at all-time highs for each respective month, and, in early October, they recorded the highest single-day flows that we’ve seen since December 2009. For decades, liquidity at the U.S. natural gas benchmark pricing location in southeastern Louisiana has been dominated by financial trades, with minimal physical exchange of gas, despite the hub boasting robust physical infrastructure and ample pipeline connectivity. That’s still the case, but physical movements of gas in the area have been on the rise due to LNG exports ramping up from the Sabine Pass and Cameron LNG facilities in southwestern Louisiana and a slew of Appalachia gas supply pipelines targeting that export demand. As more physical gas is moving through the hub, operational constraints are developing at key interconnects there. That, along with the ups and downs of LNG feedgas demand, is contributing to spot price volatility at the hub and, at times, a deeper divergence between Henry spot and futures prices. Today, we begin a short blog series on the changing gas flow dynamics in and around Henry. 

The natural gas market dynamics that were expected to turn gas flow patterns and price relationships in the Eastern U.S. on their heads and, in turn, transform supply-demand dynamics in Louisiana — including around the U.S. price benchmark Henry Hub — have come to fruition. LNG exports have surged as new liquefaction and export terminals have come online, injecting a new demand source along the Louisiana coastline. Producers have lined up to serve that demand. And midstreamers have worked to get the gas there, reversing and expanding existing northbound pipelines to move gas south into and through the Bayou State. Now, Louisiana’s gas market is nearing a critical juncture: the pipelines that connect the supply gateways in northern Louisiana to the demand centers along the Gulf Coast are nearing saturation. Today, we begin a series providing an update on Louisiana’s gas pipeline constraints and the projects lining up to alleviate them.

After a major decontracting and partial recontracting last fall, Tallgrass Energy’s Rockies Express Pipeline headed into 2020 with 839 MMcf/d in firm, long-haul commitments for natural gas moving east out of the Rockies for delivery into the Midwest. That volume is down from 1.3-1.8 MMcf/d in firm commitments previously. The contracted volume is also much lower than the peak — and even the average — historical gas flows on the route to the Midwest markets in recent years. At the same time, Tallgrass’s Cheyenne Connector pipeline and Cheyenne Hub Enhancement projects are expected to bring as much as 800 MMcf/d of new firm gas supply from the Denver-Julesburg (D-J) Basin to the REX mainline at Cheyenne Hub. What will these changes mean for Rockies’ eastbound flows and prices? Today, we wrap up our series on REX’s recontracting with an assessment of how the recent contract changes could affect REX gas flows.

For much of the time since it began operations, the capacity on Tallgrass Energy’s Rockies Express Pipeline has been contracted and utilized at high rates for long-haul flows east from the Rockies to the Midwest. Specifically, the pipeline consistently has had between 1.3 and 1.8 Bcf/d out of a total 1.8 Bcf/d contracted, mostly for 10-year terms. That all changed in the past year, however, as the original long-term shipper contracts that took effect in 2009 came due and the pipeline experienced a major decontracting, with the bulk of the contracts rolling off in November 2019. Since then, a number of open seasons led to a partial recontracting. Tallgrass also is developing two projects — Cheyenne Connector and REX Cheyenne Hub Enhancement — that could increase flows to REX later this year. Today, we continue a series providing an update on eastbound pipeline contracts and gas flows on REX.
