Colonial Pipeline

You might have thought the flurry of acquisitions and buyout deals that midstream companies entered into over the past couple of years would have satisfied their evident desire to refocus, expand and reshape their businesses. But you’d be wrong. In the first half of 2025 — a period of considerable uncertainty in the energy industry — midstream players continued to buy and sell pipelines and other important assets at a frenetic pace. In today’s RBN blog, we discuss some of the more interesting recent transactions and what they tell us about the midstream space. 

Edgewater Midstream, a relatively new player in the refined products storage and delivery space, acquired a pair of potentially valuable assets from Shell in the Deer Park, TX, area in December. It now owns the Colex terminal, the starting point of the all-important Colonial Pipeline system, and the Sinco products pipe network, which could offer another pathway to Desert Southwest markets served by a dwindling number of California refineries. In today’s RBN blog, we will examine Edgewater’s new assets and the market opportunities they may open up. 

PADD 1 — the East Coast — represents about 31% of total U.S. consumption of refined products (and 37% of its population) but is home to just 5% of U.S. refinery capacity. With only minimal in-region crude oil production, PADD 1 refineries are almost entirely dependent on imported and domestic inflows of both crude oil and products like gasoline, diesel and jet fuel. In the early years of the Shale Era, large volumes of domestic crude were railed or barged to these refineries, but in recent years they’ve again become largely reliant on imports from OPEC, Canada and other foreign sources. In today’s RBN blog, we’ll look into PADD 1’s changing crude oil and refined products supply and demand balance. 

We all hope that by the time you read this the operators of the ransomware-impacted Colonial Pipeline will have been able to restore service to more of the 5,500-mile refined products delivery system — maybe even to all of it. In any case, the shutdown of the Houston-to-New-Jersey pipeline system on Friday both exposes the vulnerability of the North American pipeline grid to malevolent hackers and reveals how, by its very nature, that same grid offers at least some degree of redundancy and resiliency built into it. A lot of that ability to respond to a crisis, whether it be a pipeline leak or a hack by an Eastern European criminal group called DarkSide, involves what you might call “market-inspired workarounds” — alternative suppliers reacting to an anticipated supply void and potentially higher prices by jumping into action. Today, we look at what the ransomware attack on the U.S.’s largest gasoline, diesel, and jet fuel transportation system can teach us.

The increase in waterborne flows to the East Coast in response to the recent Colonial Pipeline outage illustrated the flexibility of supply in the U.S. motor gasoline market. At the same time, the lack of a lasting impact from the loss of 8.3 million barrels of gasoline to a key U.S. demand region highlighted the degree of oversupply in the market. Today we look at how waterborne flows helped to mitigate the effects of the Colonial Pipeline outage, and how flexibility in the East Coast motor gasoline market enabled it to handle unexpected supply constraints with minimal disruption.

Most of the gasoline, diesel, heating oil and jet fuel consumed in the U.S. East Coast region is piped in via long-distance pipelines from Gulf Coast refineries, but substantial amounts are moved in by ship—either from the Gulf Coast by Jones Act vessels or from overseas. These shipped-in volumes then need to make their way from port to consumer. Today we continue our examination of how transportation fuels and heating oil are delivered to East Coast users with a look at the ports and connecting pipelines that help move these critically important fuels.

Every day, refineries along the U.S. Gulf Coast produce far more gasoline, diesel and jet fuel than the region could possibly use, and demand for these fuels along the East Coast for transportation and heating is far higher than local refinery production. To help bring the two regions into balance, a complicated network of pipelines, ports, Jones Act vessels and storage facilities has been developed over the past 70 years—and continues to be updated and expanded. Today, we begin a new series on how millions of barrels of these fuels are moved between and within the nation’s largest refining region and the region where more is used than any other part of the U.S.

The Colonial System is the largest refined products pipeline in the U.S. and delivers as much as 2.7 MMb/d from Gulf Coast refineries to destinations up the East Coast as far as New York. The southern section of the pipeline has been running full for over three years – leading Colonial to apportion space to shippers. A desire to gain shipper support to expand the pipeline led Colonial to propose new tariff clauses limiting trading practices that have developed around apportionment such as the sale of shipper history. Earlier this month (December 3, 2015) the Federal Energy Regulatory Commission (FERC) postponed the latest Colonial tariff proposal pending a user conference to resolve differences between the pipeline and shippers on these issues. Today we explain the oddities of line space and shipper history trading.

While recent analysis has raised concerns crude oil pipelines are running half empty the opposite is true for many of the nations’ refined product distribution pipes. Take the huge Colonial Pipeline system that delivers as much as 2.7 MMb/d of refined products from Gulf Coast refineries to destinations up the East Coast as far as New York. The southern stretch of the pipeline from Pasadena near Houston to Greensboro, NC has been running full since 2012 - meaning that shipper volumes are subject to rationing or apportionment. Today we start a two-part series explaining why the Colonial pipeline is so congested and how it operates.

The New York market for residential and commercial heating oil is traditionally tight in the winter months when demand exceeds local production and supplies are supplemented from storage and inflows/imports from outside the region. Coming into winter this year inventory levels were above normal for the time of year and market prices are in contango (a condition where future prices are higher than today) – encouraging further storage. Today we explain how the result is an extension of traditional seasonal storage trade opportunities and a shortage of available inventory capacity.
