A diluent is normally blended with the oil sands bitumen to allow it to flow in pipelines.For the purpose of meeting pipeline viscosity and density specifications, oil sands bitumen is blended with either synthetic crude oil (synbit) and/or condensate (Dilbit)." In a study commissioned by the U. Department of State (DOS), regarding the Environmental Impact Statement (EIS) for the Keystone XL pipeline project, the DOS assumes "that the average crude oil flowing through the pipeline would consist of about 50% Western Canadian Select (dilbit) and 50% Suncor Synthetic A (SCO)." like WCS.WTI is a light crude oil, lighter than Brent Crude oil.It contains about 0.24% sulfur, rating it a sweet crude, sweeter than Brent.Both Edmonton Par and WTI are high-quality low sulphur crude oils with API gravity levels of around 40°.In contrast, WCS is a heavy crude oil with an API gravity level of 20.5°." West Texas Intermediate WTI is a sweet, light crude oil, with an API gravity of around 39.6 and specific gravity of about 0.827, which is lighter than Brent crude.
According to Argus, in 2012 the WCS blend is produced by only the four companies mentioned above.The price of petroleum as quoted in news in North America, generally refers to the WTI Cushing Crude Oil Spot Price per barrel (159 liters) of either WTI/light crude as traded on the New York Mercantile Exchange (NYMEX) for delivery at Cushing, Oklahoma, or of Brent as traded on the Intercontinental Exchange (ICE, into which the International Petroleum Exchange has been incorporated) for delivery at Sullom Voe.West Texas Intermediate (WTI), also known as Texas Light Sweet, is a type of crude oil used as a benchmark in oil pricing and the underlying commodity of New York Mercantile Exchange's oil futures contracts."Mexico’s government insulated itself from the oil slump after it managed to hedge 212 million barrels of planned exports for 2016, using options contracts to secure an average price of a barrel.The nation’s 2015 oil hedge provided it with a bonus of .3 billion." "The extremely viscous oil contained in oil sands deposits is commonly referred to as bitumen" (CAS 8052-42-4) At the Husky Hardisty terminal, Western Canadian Select is blended from sweet synthetic and condensate diluents from 25 existing Canadian heavy conventional and unconventional bitumen crude oils.
"[T]he prospects for adding new producers are complicated by the internal rules set in place to compensate each producer for its contributions to the blend." Crude from MEG’s 210,000-barrel-a-day Christina Lake oil sands site is marketed as Access Western Blend, which competes with WCS. and Northern Blizzard Resources Inc also benefit from the higher WCS price.
