Matt - A bit outside my comfort zone but I’ll take a shot.. It’s more a combination of the different pieces. As I understand the middle weight crudes have always been valued more. The heavies and the very lights, like Eagle Ford, don’t create the same profit margins. OTOH some refineries are geared to handling the heavies (like Texas refineries and Vz crude). So different refineries are impacted differently as crude characters change over time. Some refineries were upgraded to handle the swing...many weren't. But then the Canadian syncrude and Eagle Ford light hit the market. And then add the distribution problems. As I understand this is a big reason why EFS light is being shipped form Texas in ever increasing volumes to eastern Canadian refineries while Alberta oil sands production is shipped in the opposite direction to Texas.
And then enter China. From what I read their refinery designs are more efficient and yield a higher motor fuel proportion. They are also being built to the specifics specs of their JV partners' oil. But I think the most significant aspect is that there is zero demand today for new refining capacity. Every bbl of oil produced today is being bought by some refinery. And refineries have to be run on a large volume basis to be very profitable. So the BIG questions: which refineries in what countries are in the process of losing some of their crude supplies? And then the next question: how efficiently will they handle what crude is available to them?
I have these and a lot more questions. More questions than I have answers for. China may be making a huge financial blunder by expanding refinery capacity in a world already at capacity. But by linking these refineries through JV’s with oil exporters I don’t think they are.
Here’s some refinery filler you might want to thumb thru:
“Generally speaking 40 to 45 API gravity degree oils have the greatest commercial value because they are rich in gasoline. Condensates are worth slightly less because the natural gasoline has a lower octane value. Heavier crudes are worth less because they require more refinery processing. West Texas Intermediate (WTI) is the benchmark crude oil used by the United States to set prices and compare other oils. It has 38 to 40 API gravity.
And gravity isn’t the only factor:
“Sour Crude - Crude oil containing free sulfur, hydrogen sulfide (H2S), or other sulfur-containing compounds in amounts greater than 1% is considered sour crude (SPE definition). As is the case with sour gas, the sulfurs must be removed from the crude oil before the oil can be refined and the refiner pays less for oil that contains sulfur. Sour crude is usually processed into heavy oil such as diesel and fuel oil rather than gasoline to reduce processing costs.”

• Since late last year, the widening differential between the Western Canadian Select (WCS) and West Texas Intermediate (WTI) benchmarks – commonly referred to as the bitumen bubble – has stolen the headlines as limited refinery capacity and pipeline constraints, combined with increased production by U.S. oil producers, have driven down the price Alberta’s heavy oil commands. However, there is more to Canadian oil than just the heavy oil priced at WCS.
• Infrastructure constraints have also weighed on the prices received for other blends of oil from the western region. Eastern Canadian oil producers benefit from access to tidewater ports and receive higher Brent-benchmarked prices for its lighter oil.
• The economic impact from a depressed oil price environment has been more pronounced in nominal terms, as corporate profits and government revenues clearly took a hit in 2012. Real economic activity has been affected as well.
• Canadian crude price conditions have improved so far in 2013 and recent data on investment intentions show that the crude oil industry is not pulling in its horns. Still, price differentials remain abnormally wide, imposing a significant opportunity cost to Canada’s economy.
Put simply, not all crude oil is created equally. Heavy crude oil has a higher density, flows through pipelines more slowly and is typically more expensive to refine relative to lighter blends. As a result, the market price for heavier oil will be lower than lighter blends, all things equal. Table 1 also distinguishes between non-conventional and conventional crude oil, oil well method. Bitumen comprises all of Canada’s non-conventional oil, and is either converted into heavy oil or upgraded to synthetic light crude.
Despite the rising share of heavy oil in Canada’s overall production mix, about three-fifths of overall production remains of the light variety. According to National Energy Board data, Saskatchewan is a more oriented towards heavy oil production (two-thirds of its total) than Alberta (40%).Newfoundland and Labrador rounds out the “big three” in Canada and currently only produces light oil (this will change once the Hebron project comes on-line in 2017). A closer look at prices Historically, there are two crude prices that have received the lion’s share of attention in Canada – the international Brent benchmark (sourced at the North Sea) and West Texas Intermediate (WTI) at Cushing Oklahoma, the latter of which forms the basis of crude pricing in North America. As shown in Table 2, this list includes Western Canadian Select (WCS), which is a heavy crude benchmark blend, Edmonton Par and Syncrude Sweet.
