Understanding Western Canadian Select Crude Oil

Western Canadian Select Crude Oil is a type of heavy crude oil that is extracted from the oil sands in Western Canada.

It has a high content of heavy hydrocarbons, which makes it difficult to refine into lighter products like gasoline and diesel. This is why it's often blended with lighter crudes to make it more suitable for refining.

The oil is extracted from the oil sands in a process that involves mining and upgrading the bitumen.

Canada was exporting 3,026,000 barrels per day to the United States by September 2014, peaking at 3,789,000 barrels per day in September 2015.

Production of petroleum and other liquids in Canada totaled 4.5 million barrels per day in 2015 and is expected to average 4.6 million barrels per day in 2016 and 4.8 million barrels per day in 2017. This increase is driven by growth in oil sands production of about 300,000 barrels per day by the end of 2017.

Shutting down an oil sands project would cost between $500 million to $1 billion, making it more cost-effective to operate at a loss.

In 2004, Suncor Energy, Cenovus Energy, Canadian Natural Resources, and Talisman Energy (later Repsol) developed the Western Canadian Select (WCS) blend.

The WCS blend was still produced by only four companies in 2012 due to complex rules regarding contributions to the blend.

Cenovus and Husky merged by January 2021, with Cenovus operating as the resulting company.

Through the merger, Cenovus became the third-largest crude oil and natural gas company and the second-largest upgrader in Canada.

Canada's oil exports to the United States have been increasing steadily over the years. By September 2014, Canada was exporting 3,026,000 bpd to the United States.

This number peaked at 3,789,000 bpd in September 2015, and 3,401,000 bpd in October 2015, which represents 99% of Canadian petroleum exports.

In 2010, the threshold volumes of WCS were only approximately 250,000 b/d.

Canada's oil production is expected to continue growing, with an average of 4.6 million b/d in 2016 and 4.8 million b/d in 2017.

Lowering production costs is crucial for the oil industry, especially when it comes to the expensive oil sands. WCS is very expensive to produce, but there are exceptions like Cenovus Energy's Christina Lake facility which produces some of the lowest-cost barrels in the industry.

Cenovus Energy's Christina Lake facility is a great example of innovation in action. General Electric's (GE) Global Innovation Centre in Calgary, which opened in 2012, is working on making the oil sands more eco-friendly. The centre is attempting to embed innovation directly into the architecture.

GE's thermal evaporation technology, developed in the 1980s, was repurposed in 1999 to improve on the water-intensive Steam Assisted Gravity Drainage (SAGD) method used to extract bitumen from the Athabasca Oil Sands. This technology has been widely adopted, including at Petro-Canada's MacKay River facility, which installed a GE SAGD zero-liquid discharge (ZLD) system in 1999 and 2002.

Suncor Energy is also exploring the strategy of replication, where engineers design an "ideal" small-capacity SAGD plant that can be replicated through successive phases of construction with cost-saving "cookie cutter", "repeatable" elements. This approach has the potential to significantly reduce production costs.

Here are some examples of the cost of production for various oil-producing regions:

These numbers give you an idea of just how expensive it can be to produce oil in certain regions. However, with the right technology and innovations, it's possible to lower production costs and make oil production more sustainable.

Curtailment was introduced in 2019 to address the issue of pipeline bottlenecks in Western Canada, which were costing the industry and governments millions of dollars a day in lost revenue.

The NDP government under Premier Notley set temporary production limits of 3.56 million barrels per day, which came into effect on January 1, 2019.

The curtailment program was deemed necessary due to chronic pipeline bottlenecks out of Western Canada.

The price of WCS rose to US$26.65 a barrel after the announcement of mandatory oil production cutbacks in Alberta.

The global price of oil dropped dramatically in December before recovering in January, leading to an increase in the price of WCS to US$28.60 with WTI at US$48.69.

The UCP government under Premier Kenney extended the curtailment program into 2020 and increased the base exemptions for companies before the quotas kick in.

This change lowered the number of producers affected by curtailment to 16.

Integrated producers, such as Imperial Oil and Husky Energy, oppose curtailment because it limits their ability to expand production above their mandated quotas.

Suncor Energy, Cenovus Energy, and Canadian Natural Resources agreed to increase production with the mandatory use of oil-by-rail as a condition for the increase.

This move was seen as a way to match takeaway capacity with produced capacity, which is the whole point of curtailment.

The Sarnia Lambton Bitumen Upgrading Project is a massive undertaking with a price tag of $10 billion. It's a high-priority national scale project, according to the Canadian Academy of Engineering, which identified it as such in July 2014.

By April 2013, Imperial Oil's Sarnia, Ontario refinery was the only plugged-in coking facility in eastern Canada that could process raw bitumen, handling a capacity of 121,000 barrels per day.

The project's goal is to produce refinery-ready crudes, which would be a game-changer for the industry. The upgraded crudes would be ready for processing at refineries like Imperial Oil's Sarnia, Ontario refinery, which has been processing WCS (Western Canada Select) since September 2013.

Western Canadian Select (WCS) trades at a discounted price compared to West Texas Intermediate (WTI) due to quality differences. WCS is a heavy crude oil with a higher density and sulfur content, making it less desirable and requiring more refining to produce valuable end-products.

The transportation costs of WCS are also a significant factor in its discounted price. WCS is produced in the landlocked province of Alberta, Canada, which creates transportation challenges, often requiring pipelines or rail to reach refineries.

The Canadian Heavy Oil Discount, also known as the WCS pricing differential, is the difference between the price of WCS and WTI. This discount is around 15-20% of the WTI price, making WCS a cheaper option for refineries. However, WCS prices govern the selling price for most heavy oils produced in Western Canada.

The cost of production is a crucial factor in determining the price of oil. The average breakeven price for oil from the oil sands was US$83 in 2019, making it the most expensive to produce.

Rystad Energy, an independent energy research and consultancy, reported that Saudi Arabia had the cheapest production costs at US$8.98 per barrel in 2016. Brazil and Nigeria had higher production costs, at US$34.99 and US$28.99 per barrel, respectively.

In 2014, a comparison of the cost of cumulative crude oil production showed that Saudi Arabia had a cost of production of US$10-25 per barrel. The oil sands in Canada had a much higher cost of production, ranging from US$53 to US$90 per barrel.

The weighted average cost of production for oil sands in Canada was around US$60-61 per barrel, which includes existing integrated oil sands at C$53 per barrel.

The price of Western Canadian Select (WCS) is often lower than that of West Texas Intermediate (WTI) due to quality differences. WCS is a heavy crude oil with a higher density and sulfur content compared to WTI.

Transportation costs also play a significant role in the price differential. WCS is produced in landlocked Alberta, Canada, which creates transportation challenges, often requiring pipelines or rail, to reach refineries.

Limited market access is another factor contributing to the discount. Historically, Western Canada has faced challenges in accessing global markets due to limited pipeline infrastructure connecting the region to coastal ports.

The discount between WCS and WTI can also be influenced by seasonal factors, such as colder temperatures making it more difficult to transport and process the heavy crude.

Geopolitical and regulatory factors can also impact the pricing of WCS, affecting supply-demand dynamics in the crude oil market.

Market perception and investor sentiment can also influence the pricing of WCS, with factors such as environmental impacts, regulatory hurdles, and social considerations affecting investor sentiment and leading to a discount.

The prices of various crude oil types are interconnected, and fluctuations in global crude oil prices can impact the price differential between WCS and WTI.

Here are some key price assessments that can help illustrate the WCS pricing discounts:

These price assessments are recognized by the market as trusted and reliable indicators of the real market value, providing valuable insights into the WCS pricing discounts.

Western Canadian Select (WCS) is a type of heavy crude oil that requires more refining and processing to produce valuable end-products like gasoline and diesel due to its higher density and sulfur content compared to light crude oils.

The average US crude import has an API of about 25°, which is significantly lower than the API of WCS. This highlights the quality differences between WCS and other types of crude oils.

US refineries have been forced to process more light oil, bringing the average feedstock API back above 33° by the end of 2019, which is still lower than the API of WCS.

The transportation costs associated with WCS, which is produced in the landlocked province of Alberta, Canada, further reduce its market value.

The price of crude oil can vary significantly depending on its quality, location, and market demand. WCS, a heavy crude oil produced in Western Canada, often trades at a discounted price compared to WTI, a benchmark light crude oil produced in the United States.

This discount is largely due to the quality differences between the two crudes. WCS has a higher density and higher sulfur content compared to WTI, making it more difficult and expensive to refine.

The transportation costs of WCS also contribute to its discounted price. WCS is produced in the landlocked province of Alberta, Canada, which creates transportation challenges and increases costs.

Limited market access is another factor that affects the price of WCS. Historically, Western Canada has faced challenges in accessing global markets due to the limited pipeline infrastructure connecting the region to coastal ports.

Seasonal factors can also impact the price differential between WCS and WTI. For example, during the winter months, WCS prices can be further discounted as colder temperatures make it more difficult to transport and process the heavy crude.

The prices of various crude oil types are interconnected, and fluctuations in global crude oil prices can impact the price differential between WCS and WTI.

Here's a snapshot of the most common North American benchmarks and key foreign imports:

The Bakken formation in North Dakota has also had a significant impact on the price of WCS. The rapid growth in oil production from the Bakken has increased competition for pipelines and railway space, making it more difficult for WCS to access transportation.

By the end of 2010, oil production rates in the Bakken had reached 458,000 barrels per day, outstripping the pipeline capacity to ship oil out of the region. This has led to a surplus of oil in the region, which has further discounted the price of WCS.

Refineries play a crucial role in the refining and markets process. US refineries have the capacity to process heavy oil from the oil sands, specifically the WCS blend, which is transported from Alberta.

The Petroleum Administration for Defense Districts (Padd II) in the US Midwest has experience running the WCS blend. Most US refiners have invested in more complex refinery configurations with higher processing capability.

US refineries import large quantities of crude oil from Canada, Mexico, Colombia, and Venezuela. In fact, medium and heavy crude oil make up 50% of US crude oil inputs.

US refineries have made significant investments in complex refining hardware, which supports processing heavier, sourer crude into gasoline and distillates. This has allowed the US to expand its capacity to process heavy crude.

There are only 19 refineries in Canada compared to 148 in the United States. Canadian refineries are not equipped to process WCS crude oil, which requires specialized refining.

The Pine Bend Refinery in Minnesota is a significant player in the oil refining industry. Located in the Twin Cities, it's the largest oil refinery in the state.

This refinery receives a substantial 80% of its heavy crude from the Athabasca oil sands. The crude oil is piped from the northwest to the facility through the Lakehead and Minnesota pipelines.

The Pine Bend Refinery has a notable nameplate capacity of 330,000 barrels per day, making it a major producer in the country. By 2013, it was ranked 14th in the country by the U.S. Energy Information Agency.

The refinery's pipeline system stretches across Minnesota and Wisconsin, covering a vast 537-mile distance.

Western Canadian Select (WCS) is transported by rail, with Canadian Pacific Railway (CPR) being a major player in this industry.

In 2014, CPR's COO Keith Creel said that WCS transport would account for one-third of CPR's new revenue gains through 2018, aided by improvements at oil-loading terminals and track in western Canada.

CPR's high capacity North Line runs from Edmonton to Winnipeg, connected to all the key refining markets in North America.

Pipelines play a crucial role in transporting crude oil from Alberta to other parts of North America.

As of March 31, 2020, Western Canadian crude oil export pipelines have a total estimated export capacity of 4,230,000 b/d.

Several major pipelines have been constructed since 2012 to alleviate the "landlocked" issue, including Seaway, the Southern leg of Keystone XL and Flanagan South.

However, pipeline capacity remains a significant obstacle, with Alberta facing a "pipeline capacity wall" around 2016, as warned by the Canada West Foundation in April 2013.

Rail shipments of crude oil have filled the gap and narrowed the price differential between Albertan and North American crudes.

The Portland–Montreal Pipe Line Corporation is considering a proposal to carry Canadian oil sands crude to Atlantic tidewater at Portland's deep-water port, which would involve piping crude via the Great Lakes, Ontario, Quebec, and New England.

The rail industry has undergone significant changes in recent years. Canadian Pacific Railway (CPR) was in a growth position in 2014 due to increased Alberta crude oil transport.

In 2014, CPR's COO Keith Creel said that the transport of Alberta's heavy crude oil would account for about 60% of the CP's oil revenues. Light crude from the Bakken Shale region in Saskatchewan and the US state of North Dakota accounted for 40% of CPR's oil shipments.

CPR's high capacity North Line, which runs from Edmonton to Winnipeg, is connected to all the key refining markets in North America. This makes it an ideal route for shipping Alberta oil east.

The Lac-Mégantic rail disaster and other oil-related rail incidents led to tougher regulations in both Canada and the US. As a result, Bakken crude's share of CPR's oil shipments decreased from 60% to 40%.

The transport of heavy crude oil is considered safer and less volatile than Bakken crude. It's also more profitable to move, which is why CPR is uniquely positioned to take advantage of this market.

Western Canadian Select (WCS) is a type of crude oil that's commonly referred to as dilbit. It's a blend of bitumen and a diluent, typically synthetic crude oil or condensate, which allows it to flow in pipelines.

The density of WCS is around 930.1 kg/m3, with a range of 926.9 to 935.7 kg/m3 depending on the sample. This is due to the blending process, which can affect the overall density of the oil.

WCS has a relatively low API gravity level, ranging from 19 to 22 API. This means it's a heavy crude oil that requires special handling and processing. The sulfur content of WCS is around 2.8-3.5%, which is relatively high compared to other types of crude oil.

Here's a summary of WCS's key characteristics:

The Total Acid Number (TAN) of WCS is typically maintained under 1.1, which is relatively low compared to other types of crude oil. This is because WCS is often blended with light, sweet crudes and condensate to reduce its TAN value and make it more suitable for refining.

A fresh viewpoint: Garry Tan San Francisco

The oil industry is full of complex relationships between different types of crude oil. One interesting dynamic is the competition between Alaska North Slope (ANS), Western Canadian Select (WCS), and Bakken oil for transportation and refining.

Bakken oil, in particular, has been a game-changer in the industry. By 2012, oil production from the Bakken formation alone was forecast to grow by 600,000 barrels every year through 2016.

The rapid growth of Bakken oil production has led to a surge in demand for pipelines and railway space. By the end of 2010, oil production rates had reached 458,000 barrels per day, outstripping the pipeline capacity to ship oil out of the Bakken.

WCS and Bakken oil compete for access to these transportation networks, making it challenging for refineries to manage their supply chains. This competition has created opportunities for refineries capable of blending and refining cheaper crude blends, like WCS.

In fact, John Auers and John Mayes suggest that a "pseudo" Alaskan North Slope substitute could be created with a blend of 55% Bakken and 45% Western Canadian Select at a cost potentially far less than the ANS market price.

Western Canadian Select (WCS) is a type of oil that is commonly referred to as bitumen. It has a high viscosity, which means it doesn't flow naturally in pipelines, so a diluent is added to make it flowable.

The API gravity level of WCS is between 19 and 22, which is relatively low. This means WCS is a dense oil, with a density of 930.1 kg/m3.

WCS contains 2.8-3.5% sulfur, which is a significant amount. Refineries in North America consider a crude with a Total Acid Number (TAN) value greater than 1.1 as "high-TAN", and WCS's TAN value is consistently maintained under 1.1 through blending with light, sweet crudes and condensate.

Here are the key characteristics of WCS:

Western Canadian Select has been analyzed for various properties, and the data reveals some interesting trends.

The most recent sample, taken on September 2, 2025, showed elevated density at 935.7 kg/m³, which is higher than the five-year average of 926.9 kg/m³.

Sulphur levels were also higher than average, at 3.83 wt%, compared to the five-year average of 3.66 wt%.

Micro Carbon Residue (MCR) was measured at 10.4 wt%, which is above the five-year average of 9.88 wt%.

The sample also had elevated vanadium levels, at 141.0 mg/kg, compared to the five-year average of 131.0 mg/kg.

Let's take a closer look at the Light Ends data:

The most recent sample had lower levels of C3- (0.07 vol%) and iC4 iso-Butane (0.74 vol%) compared to the five-year average.

The sample also showed lower levels of C6 Hexanes (3.60 vol%) and C7 Heptanes (2.71 vol%) compared to the five-year average.

The density of the sample has been increasing over the past few months, from 931.2 kg/m³ on July 4 to 935.7 kg/m³ on September 2.

The sediment levels in the sample were measured at 217 ppmw, which is higher than the five-year average of 203 ppmw.

The Bakken formation in North Dakota has been a game-changer for oil production. By 2012, oil production from the Bakken formation alone was forecast to grow by 600,000 barrels every year through 2016.

This rapid growth has put a strain on pipelines and railway space, as WCS and Bakken compete for access to transportation. By the end of 2010, oil production rates had reached 458,000 barrels per day, outstripping the pipeline capacity to ship oil out of the Bakken.

The increased competition has also led to a decrease in the demand for heavy crude in the US, with the average US crude import having an API of about 25°. This is in contrast to the average US refinery feedstock, which has an API of about 33°.

The US government lifted the export ban in 2016, allowing the country to export light oil and import more heavy crude. This change had a significant impact on the demand for Alberta's heavy crude.

US refineries were initially able to process more heavy crude, with an average feedstock API of 31° by 2017. However, limited export capacity and rising light oil production from US shale soon forced refineries to process more light oil.

Additional reading: Light S.A.

By the end of 2019, the average US refinery feedstock API had risen back above 33°. This is a result of the dwindling supplies of heavy crude and the increasing availability of light oil from US shale.

Here's a comparison of the average US refinery feedstock, crude production, and crude imports by API:

The contrast between US refinery feedstock and crude imports highlights the changing dynamics of the US oil market.

The Bakken formation has been producing oil at an incredible rate, with forecasts suggesting growth of 600,000 barrels per year through 2016. This rapid growth has put a strain on pipeline capacity, with oil production rates reaching 458,000 barrels per day by the end of 2010.

This increased production has led to competition for pipelines and railway space, making it difficult for WCS to access transportation. By the end of 2014, the rapid oil output growth in the Bakken had destabilized international oil markets.

The Bakken's impact on WCS is a complex issue, but one thing is clear: the two types of oil are competing for limited resources. Here's a breakdown of the average API for US refineries, production, and imports:

The average US crude import has an API of about 25°, which is significantly lower than the average US refinery feedstock of 33° by the end of 2019. This suggests that US refineries are processing more light oil, which is likely a result of the increased production from the Bakken.
