Oil from Canada supplies more than 23% of U.S. refinery feedstock, helping bolster North American energy security

Introduction

The refining industry¹ in the United States is one of the world’s largest, with capacity to process 18 million barrels of oil per day. Canada plays a crucial role by supplying more than one-fifth of the crude oil refined in the U.S.

The U.S.–Canada cross-border crude oil trade is essential to North American energy security. Canadian crude oil exports and the U.S. refinery industry are highly integrated. In recent years, Canada’s crude oil sector has been making a growing contribution to the operations of U.S. oil refineries.

U.S. refineries are converting Canadian crude oil, including heavy oil,² into products that North Americans use daily, such as transportation fuels (gasoline and diesel), chemicals, and plastics. Although the U.S. has increased its production of oil in recent years, U.S. refineries still rely on Canadian heavy crude oil to meet their feedstock (i.e., the raw materials and intermediate materials processed at refineries to produce finished petroleum products, otherwise known as refinery inputs) specifications.

In this CEC Fact Sheet, we examine several economic indicators that illustrate the importance of Canadian crude oil, particularly heavy crude, to U.S. refineries. This fact sheet also analyzes the refining industry’s direct and indirect economic impacts on the U.S. economy.

1. NAICS Code 324110 (Petroleum Refineries): This industry comprises
establishments primarily engaged in refining crude petroleum into refined petroleum.

2. A majority of the crude oil imported by the U.S. from Canada is heavy crude (between 15-25 API gravity). API gravity is a commonly used index for measuring the density of crude oil or refined products. Crude oil typically has an API between 15 and 45 degrees. The higher the API, the lighter the crude; the lower the API, the heavier the crude.

Imports of Canadian crude oil to refineries in the United States

The physical characteristics of crude oil determine how it is processed in refineries. Generally, heavy crude oil offers higher yields of low-value products (coke and asphalt) and lower yields of high-value products (gasoline). Heavy crude oil requires more complicated processing than lighter crude if it is to produce high-value products.

Overall, Canadian crude oil imports to U.S. refineries for processing have risen from over 1.3 million barrels per day in 2000 to just under 3.8 million barrels per day in 2022, an increase of 181 per cent (see Figure 1). The per cent of Canadian crude in U.S. refinery feedstock has steadily risen from nearly 9 per cent in 2000 to over 23 per cent by the end of 2022.

The U.S. refining industry

Since the first U.S. refinery began operating in 1861, the refining industry has been one of the largest manufacturing sectors in the United States. There are currently 129 petroleum refineries across the five U.S. PADDS³ (125 operating refineries and five refineries that are idle but not permanently shut down) (see Table 1).

3. The United States is divided into five Petroleum Administration for Defense 
Districts (PADDs) for the allocation of fuels derived from petroleum products, 
including gasoline and diesel fuel. The geographic breakdown of PADDs enables 
U.S. policymakers to better analyze petroleum supplies in the country

Total refining capacity in the United States has risen from 16.2 million barrels of crude processed in 2000 to nearly 17.8 million barrels per day in 2022, an increase of over 8 per cent (see Figure 2). The refining utilization⁴ has also recovered, growing from 79 per cent during COVID-19 to a high of 91 per cent in 2022.

The impact of the U.S. refining industry on the American economy

The estimated direct and indirect economic impacts of the U.S. refining industry in 2024 include 1.6 million direct and indirect jobs, $206 billion in labour income, $577 billion in direct and indirect value-added, and $1.6 trillion in what is known as “outputs,” i.e., the value of goods and services produced by the industry (see Table 2).⁵

Utilization measures how much is actually being processed (as a percentage of 
maximum capacity).

Projected spending by the U.S. refining industry, 2024-2030

Figure 3 illustrates the industry’s projected annual spending between 2024 and 2030. Industry spending is expected to be US$58 billion in 2024, rising to US$62 billion by 2030. This includes operating expenditures (OPEX) and capital expenditures (CAPEX). Cumulatively, between 2024 and 2030, the industry is projected to spend over US$428 billion.⁶

Conclusion

American refineries are critical to the country’s strategic interest. U.S. refineries are projected to spend more than $428 billion in the next seven years on operating and capital expenditures. The industries support millions of jobs. Canadian crude is an important part of the equation. It supplies more than 23 per cent of U.S. refinery feedstock.

Not only are Canadian crude oil supplies critical for the U.S. refining industry, but they are key to North American energy security. Limiting access to Canadian crude oil for U.S. refineries would require increased U.S. imports from less-free countries, which in turn would risk North American energy security.

‘Weird and wonderful’ wells are boosting oil production in Alberta and Saskatchewan

Multilateral designs lift more energy with a smaller environmental footprint

A “weird and wonderful” drilling innovation in Alberta is helping producers tap more oil and gas at lower cost and with less environmental impact.

With names like fishbone, fan, comb-over and stingray, “multilateral” wells turn a single wellbore from the surface into multiple horizontal legs underground.

“They do look spectacular, and they are making quite a bit of money for small companies, so there’s a lot of interest from investors,” said Calin Dragoie, vice-president of geoscience with Calgary-based Chinook Consulting Services.

Dragoie, who has extensively studied the use of multilateral wells, said the technology takes horizontal drilling — which itself revolutionized oil and gas production — to the next level.

“It’s something that was not invented in Canada, but was perfected here. And it’s something that I think in the next few years will be exported as a technology to other parts of the world,” he said.

Dragoie’s research found that in 2015 less than 10 per cent of metres drilled in Western Canada came from multilateral wells. By last year, that share had climbed to nearly 60 per cent.

Royalty incentives in Alberta have accelerated the trend, and Saskatchewan has introduced similar policy.

Multilaterals first emerged alongside horizontal drilling in the late 1990s and early 2000s, Dragoie said. But today’s multilaterals are longer, more complex and more productive.

The main play is in Alberta’s Marten Hills region, where producers are using multilaterals to produce shallow heavy oil.

Today’s average multilateral has about 7.5 horizontal legs from a single surface location, up from four or six just a few years ago, Dragoie said.

One record-setting well in Alberta drilled by Tamarack Valley Energy in 2023 features 11 legs stretching two miles each, for a total subsurface reach of 33 kilometres — the longest well in Canada.

By accessing large volumes of oil and gas from a single surface pad, multilaterals reduce land impact by a factor of five to ten compared to conventional wells, he said.

The designs save money by skipping casing strings and cement in each leg, and production is amplified as a result of increased reservoir contact.

Q&A with Gary Mar, CEO of the Canada West Foundation

Building a stronger Canadian economy depends as much on how we move goods as on what we produce.

Gary Mar, CEO of the Canada West Foundation, says economic corridors — the networks that connect producers, ports and markets — are central to the nation-building projects Canada hopes to realize.

He spoke with CEC about how these corridors work and what needs to change to make more of them a reality.

CEC: What is an economic corridor, and how does it function?

Gary Mar: An economic corridor is a major artery connecting economic actors within a larger system.

Consider the road, rail and pipeline infrastructure connecting B.C. to the rest of Western Canada. This infrastructure is an important economic corridor facilitating the movement of goods, services and people within the country, but it’s also part of the economic corridor connecting western producers and Asian markets.

Economic corridors primarily consist of physical infrastructure and often combine different modes of transportation and facilities to assist the movement of many kinds of goods.

They also include social infrastructure such as policies that facilitate the easy movement of goods like trade agreements and standardized truck weights.

The fundamental purpose of an economic corridor is to make it easier to transport goods. Ultimately, if you can’t move it, you can’t sell it. And if you can’t sell it, you can’t grow your economy.

CEC: Which resources make the strongest case for transport through economic corridors, and why?

Gary Mar: Economic corridors usually move many different types of goods.

Bulk commodities are particularly dependent on economic corridors because of the large volumes that need to be transported.

Some of Canada’s most valuable commodities include oil and gas, agricultural commodities such as wheat and canola, and minerals such as potash.

CEC: How are the benefits of an economic corridor measured?

Gary Mar: The benefits of economic corridors are often measured via trade flows.

For example, the upcoming Roberts Bank Terminal 2 in the Port of Vancouver will increase container trade capacity on Canada’s west coast by more than 30 per cent, enabling the trade of $100 billion in goods annually, primarily to Asian markets.

Corridors can also help make Canadian goods more competitive, increasing profits and market share across numerous industries. Corridors can also decrease the costs of imported goods for Canadian consumers.

For example, after the completion of the Trans Mountain Expansion in May 2024 the price differential between Western Canada Select and West Texas Intermediate narrowed by about US$8 per barrel in part due to increased competition for Canadian oil.

This boosted total industry profits by about 10 per cent, and increased corporate tax revenues to provincial and federal governments by about $3 billion in the pipeline’s first year of operation.

CEC: Where are the most successful examples of these around the world?

Gary Mar: That depends how you define success. The economic corridors transporting the highest value of goods are those used by global superpowers, such as the NAFTA highway that facilitates trade across Canada, the United States and Mexico.

The Suez and Panama canals are two of the most significant trade infrastructure projects ever built, facilitating 12 per cent and five per cent of global trade, respectively. Their success is based on their unique geography.

Canada’s Asia-Pacific Gateway, a coordinated system of ports, rail lines, roads, and border crossings, primarily in B.C., was a highly successful initiative that contributed to a 48 per cent increase in merchandise trade with Asia from $44 million in 2006 to $65 million in 2015.

China’s Belt and Road initiative to develop trade infrastructure in other countries is already transforming global trade. But the project is as much about extending Chinese influence as it is about delivering economic returns.

CEC: What would need to change in Canada in terms of legislation or regulation to make more economic corridors a reality?

Gary Mar: A major regulatory component of economic corridors is eliminating trade barriers.

The federal Free Trade and Labour Mobility in Canada Act is a good start, but more needs to be done at the provincial level to facilitate more internal trade.

Other barriers require coordinated regulatory action, such as harmonizing weight restrictions and road bans to streamline trucking.

By taking a systems-level perspective – convening a national forum where Canadian governments consistently engage on supply chains and trade corridors – we can identify bottlenecks and friction points in our existing transportation networks, and which investments would deliver the greatest return on investment.
