You’ve probably been hearing various stories the last few weeks, like Saudi Arabia agreeing to “increase production by 300,000 barrels per day. What you’re not reading, however, is what type of crude oil this increase in production will be producing. These two stories should help you start to understand a bit more about how all this refining/crude production stuff actually works.
This first article helps explain. I just cut out the section headers to keep the quote short, but they make it fairly clear. Read the full article to get a better sense of how the global refining vs crude supply market really works, it’s interesting.
As medium sweet crude oil blends have strengthened in recent months, medium and heavier sour blends have fallen behind. In particular, Middle East heavy crudes have been unable to keep up with the growing appetite for low sulphur middle distillate products, with differentials between Saudi Super Light and Saudi Heavy crude blends widening to record levels.
…
Medium sweet crudes are becoming a preferred blend
…
Global refining bottlenecks are at the heart of the problem
…
Middle distillate demand is pulling up medium sweet crudes
…
Sulphur content in crude is again more important than gravity
…
Due to refining constraints, heavier crudes are falling behind
…
Despite strong demand, the global refining sector is disjointed
…
Only diesel, jet are helping refining margins thus pushing up medium sweets
Thus, only diesel and jet fuel are really helping keep refining margins above water. The inability of refiners to turn more gasoline, naphtha or residual fuel oil into jet and diesel has now pushed the gasoil to fuel oil spread to record levels. Merrill Lynch said this spread is unlikely to contract much until a substantial amount of new cracking and coking capacity comes on line in 2009-2010. In turn, this situation will likely continue to provide support to medium sweet grades around the world in detriment of heavier, sourer grades.
Heavy crude can’t keep up, Business Intelligence – Middle East, 08-05-2008
These heavier, sour grades, are in fact the “excess capacity” Saudi Arabia keeps talking about. And you can rest assured that when more of this sour heavy crude hits the market, the market will not be able to absorb it, then Saudi Arabia will be able to say that it was not a supply problem, but some non-geological problem, like declining value of US dollar, speculating, etc.
You may also have heard that Iran is currently unable to sell all its crude oil. How can this be when the world is supposedly peaked, and demand is exceeding supply? Read on to learn more.
